FXLData

An Excel add-in providing a collection of functions for retrieving statistical data from a Fusion Registry directly into a worksheet

Download

Download the latest version File:FXLData July2024.zip July 2024.

See the FXLData Changelog for recent changes, updates and bug fixes.

Quick start

1. Download the latest version and unzip the add-in which is a single file: FXLData.xlam
2. Install the add in
3. Open a blank Excel worksheet
4. Paste the following formula into a cell

=FXLDataV("https://demo.metadatatechnology.com/FusionRegistry","WB,WDI_POVERTY","A")

A sample 100 series of annual data will be retrieved from Metadata Technology's public demonstration Fusion Registry service and inserted directly into the sheet.

The FXLData Wizard provides tools to help with the task of building FXLData formulas.

Overview

The FXLData family of functions are Excel array formulas.

These work in the same way normal as normal single-cell funcions such as =SUM() and =STDEV() with the exception that the result is an array of series and observation values spanning a range of rows and columns.

Microsoft's documentation provides general information on how to work with array formulas in Excel.

Parameterised functions

These functions take a number of separate arguments making them suitable for building sophisticated data models where Start Period, End Period and other parameters use cell references or Excel formulas.

Horizontal time-series example

Both the horizontal and 'V' verical variants take the same arguments making it easy to switch between presentations.

=FXLData( RegUrl , Dataflow , Expression , [MaxSeries] , [RestArguments] , [StartPeriod] , [EndPeriod] , [Labels] , [IncludeHeader] , [IncludeSeriesKey] , [IncludeBreakdown] , [IncludeAttributes] )
Returns a selected dataset in 'horizontal' time-series format with one series per row

• Three mandatory arguments: the base URL of the Fusion Registry, the Dataflow, a Series Key pattern specifying what series to return
• A further nine optional arguments can be specified including: maximum number of series to retrieve, start / end period, labels, headers and whether dimensions and attributes are shown

=FXLDataV( RegUrl , Dataflow , Expression , [MaxSeries] , [RestArguments] , [StartPeriod] , [EndPeriod] , [Labels] , [IncludeHeader] , [IncludeSeriesKey] - ignored, [IncludeBreakdown] - ignored, [IncludeAttributes] )
Returns a selected dataset in 'vertical' format with one series per column

• Three mandatory arguments: the base URL of the Fusion Registry, the Dataflow, a Series Key pattern specifying what series to return
• A further nine optional arguments can be specified including: maximum number of series to retrieve, start / end period, and whether dimensions, attributes and metrics are shown
• IncludeSeriesKey is ignored
• IncludeBreakdown is ignored
• Set Labels=both to show IDs and dimensions / attributes
• If Labels=both, setting IncludeAttributes=TRUE will show the breakdown of series / dataset attributes in the header
• IncludeHeader controls whether the resultset metrics are shown at the top (e.g. 205/1276 series 1.78 seconds)

Examples

=FXLData("https://demo.metadatatechnology.com/FusionRegistry","WB,WDI_POVERTY,1.0","A...")
=FXLDataV("https://demo.metadatatechnology.com/FusionRegistry","WB,WDI_POVERTY,1.0","A...",1000,"round=2",2010,2020,"both",true,true,true,false)
=FXLData(C14,C4,C7,C15,C13,C5,C6,C12,C9,C8,C10,C11)
=FXLDataV(A9,B24,B25,1000,,min(D55,2010),max(D56,2020))

Like all Excel functions, arguments can either be literal values, cell references, or other formulas.

Functions taking a Fusion Registry data query URL

These functions take a single fully-formed Fusion Registry data query URL making them suitable for use cases where another tool such as the Fusion Data Browser has been used for data discovery, with data retrieval being performed directly in Excel.

Both the horizontal and 'V' verical variants take the same arguments making it easy to switch between presentations.

=FXLDataUrl( Url , [MaxSeries] )
Returns the selected resultset in 'horizontal' time-series format with one series per row

• Behaves in the same way as =FXLData() but takes a single mandatory argument: a fully-formed Fusion Registry data query URL
• A single optional argument allows the maximum number of series to be set

=FXLDataUrlV( Url , [MaxSeries] )
Returns the selected resultset in 'vertical' format with one series per column

• Behaves in the same way as =FXLDataV() but takes a single mandatory argument: a fully-formed Fusion Registry data query URL
• A single optional argument allows the maximum number of series to be set

=FXLDataUrlFact( Url , [MaxSeries] )
Returns the selected resultset as a data warehouse style fact table

• Takes a single mandatory argument: a fully-formed Fusion Registry data query URL
• A single optional argument allows the maximum number of series to be set
• Returns one row per observation including all series and observation attributes
• Following the traditional fact table model, only dimension and attributes codes are returned - there is not option to return code labels

Examples

=FXLDataUrl("https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/ECB,EXR,1.0/A.CAD+HUF+INR...E?round=2&labels=id")
=FXLDataUrlV("https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/ECB,EXR,1.0/A.CAD+HUF+INR...E?round=2&labels=id",1000)
=FXLDataUrlFact("https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/ECB,EXR,1.0/.CAD+MXN+MYR...",20)

Administrative functions

=FXLDataVersion()

• Returns the software version number and build date

=FXLDataVersion("changelog")

Returns the latest version of the change log

Microsoft 365 Excel 2018 and later

In Microsoft 365 versions of Excel, the FXLData functions act as dynamic array formulas which populate or 'spill' the result set into neighbouring cells on execution. There is no need for an explicit refresh because Excel will 'recalculate' any FXLData functions that have changed using its normal worksheet calculation behaviour. Settings Excel's calculation options to Automatic (the default) will automatically refresh an FXLData formula if the formula or something it depends upon such as a parameter in referenced cell has changed. If calculation is set to Manual, changed FXLData formulas will be refreshed when the user asks Excel to perform a recalculation using the Calculate Now or Calculate Sheet buttons on the ribbon bar. A complete recalculation can be forced using CTRL+ALT+SHIFT+F9.

Office 2010-2019 Excel

For these older versions of Excel which do not support dynamic array formulas, the FXLData functions work in legacy mode which emulates to some extent the dynamic array formula behaviour. On execution, the result set still populates into neighbouring cells. However, there are some important differences between legacy mode and proper dynamic arrays:

• In legacy mode, the result set is written directly into the worksheet which Excel treats as a collection of largely disconnected cells. By contrast, Excel treats a dynamic array as a single entity.
• Excel automatically protects against dyanamic arrays overwriting other content in the worksheet resulting in a #Spill! error if that would otherwise occur. Legacy mode will overwrite any existing content meaning that care is required to avoid worksheet corruption if the result set from an FXLData function is larger than expected.
• Legacy mode FXLData functions will be automatically refreshed if the formula itself is changed, but it not if a dependency of the formula changes. This is because the legacy mode refresh only emulates the proper dynamic array formuala spill behaviour.

FXLData Wizard

The FXLData Wizard is an Excel ribbon bar tool for interactively building and editing FXLData functions and comes as part of the add in.

Prerequisites

1. Fusion Registry 10.7.0 or later
2. Microsoft 365 Excel 2018 or later - supports dynamic arrays which automatically 'spill' the result set into the worksheet
3. Office 2010-2019 - FXLData functions operate in legacy mode which provides dynamic array emulation

Refer to Microsoft's documentation on dyanmic arrays and legacy 'ctrl-shift-enter' behavior.

Excel on Apple Mac is not supported because FXLData uses operating system services only available on Windows.

Function Reference

=FXLData()

By default ƒ_x =FXLData() returns a horizontal time-series dataset, one series per row with time spanning the columns i.e. time is the dimension at observation. A different dimension at observation can be chosen using the RestAuguments parameter - refer to the guidance below.

Use Case
This parameterised form is suitable for hard coding in a spreadsheet. Like all Excel functions, the arguments can be literal values, cell references or Excel expressions allowing the creation of complex data models. In its simplest form, only three arguments are required:

• The 'base URL' of the Fusion Registry to connect to
• The ID of the Dataflow
• A series key specifying which series to retrieve, or simply 'all' to retrieve all series

=fxldata("https://demo.metadatatechnology.com/FusionRegistry","WB,WDI_POVERTY","A")

By default, the number of series returned is capped at 100, but can be altered using the MaxSeries argument

Use Case

Fusion Data Browser Query Syntax function

This version of the function is designed primarily for use cases where a data query URL is generated by a data discovery tool, for example:

• The Fusion Registry REST Web Service query builder
• The Fusion Data Browser Export Data Query Syntax function

Syntax
=FXLDataUrlV( Url , [MaxSeries] )

	Argument	Description	Examples	Required?

=FXLDataUrlFact()

ƒ_x =FXLDataUrlFact() returns the selected resultset as a data warehouse style fact table with one row per observation including all series and observation attributes. As this is conceptually just the fact table of a star schema, only code IDs are returned - code labels are not available.

Use Case
This version of the function is designed for data analytics involving observation attributes. The fact table model also works well with Excel's standard Pivot Table features.

Syntax
=FXLDataUrlFact( Url , [MaxSeries] )

	Argument	Description	Examples	Required?
1	Url	A complete and fully-formed SDMX data query URL	https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/ECB,EXR,1.0/A.CAD+HUF+INR...E?round=2&labels=id	Mandatory

Client-side REST Arguments

The =FXLData() and =FXLDataV() functions support additional REST arguments to modify behaviour in Excel. These arguments are not passed to the Fusion Registry or Edge Server.

nocc - suppress completion of the resultset cube when startPeriod and / or endPeriod are specified. Under normal behaviour, the resultset will always span the time periods specified irrespective of whether there are observation values available. If nocc is specified in the REST Arguments, the resultset will only span time periods for which observations are available.
Examples:

nocc
round=2&nocc
nocc&dimensionAtObservation=REF_AREA

Legacy Mode

Legacy Mode emulates the latest Microsoft 365 dynamic array behaviour in older Office Excel 2010-2019 versions by populating the cells neighbouring that holding an FXLData formula with the data result set.

In versions of Microsoft 365 Excel that do support dynamic arrays, legacy mode can also be used to write the result set directly into the worksheet. That's useful in situations where discrete data points are needed rather than an Excel array which has certain limitations.

Office Excel 2010-2019

FXLData always works in legacy mode when using Office Excel 2010-2019.

When an FXLData function is executed, the first cell of the result set will appear as the formula result. If automatic calculation is enabled, FXLData's dynamic array emulation will immediately populate the neighbouring cells with the remainder of the result set. If automatic calculation is disabled, Refresh must be used.

Forcing Microsoft 365 Excel to use Legacy Mode

FXLData functions in Microsoft 365 Excel operate as dynamic array formulas by default where the result set appears in the worksheet as an Excel array.

Using the Implicit intersection operator: @ however forces the FXLData function to operate in legacy mode causing the result set to be written directly into the worksheet.

=@FXLData("https://registry.domain.org/FusionRegistry","ECB,EXR,1.0","A..BGN+BEF..",100,"round=2","2010","2020","id",TRUE,FALSE,TRUE,FALSE)

In the above example the @ preceeding the FXLData function name instructs Excel to return the implicit intersection of the result set array which is just the first cell. If legacy mode automatic calculation is enabled, the FXLData's dynamic array emulation will populate the neighbouring cells. If not, Refresh must be used.

Refresh

Microsoft 365 Excel and dynamic array formulas

Interactive

FXLData functions by default work as dynamic array formulas in Microsoft 365 so are refreshed using the normal Excel calculation rules:

Refresh occurs when:

• a change is made to the formula
• a change is made to something the formula depends upon such as an argument value held in another cell
• Excel is forced to recalculate open workbooks using CTRL+ALT+F9 or CTRL+ALT+SHIFT+F9
• a saved workbook is opened

The Refresh options on the FXLData ribbon do not refresh dynamic array formulas.

From Code

Refreshing FXLData from VBA, C# or C code uses the standard Excel API calculation functions, for instance:

• VBA: ActiveSheet.Calculate
• C API: xlcCalculateDocument()

Office 2010-2019 Excel and Microsoft 365 Excel working in legacy Mode

Interactive

FXLData Excel ribbon

In older versions of Office Excel and when forcing legacy mode in Microsoft 365 using the @ implicit intersection operator, FXLData functions can be manually refreshed using the Refresh options on the ribbon bar.

• Refresh Selected: refreshes the FXLData function at the current active cell
• Refresh Sheet: refreshes all FXLData functions on the current work sheet
• Refresh Book: refreshes all FXLData functions in the work book

Using Refresh in Legacy mode

From Code

The FXLData add-in exposes three public sub-routines to trigger a refresh from VBA code.

A reference to FXLDataAddin must be added to the VBA project.

Macro Example 1 - Refresh the FXLData function in the current active cell

Public Sub myMacro()
   FXLDataRefreshActiveCell
End Sub

Macro Example 2 - Refresh all FXLData functions in the workbook

Public Sub myMacro()
   FXLDataRefreshWorkbook
End Sub

Macro Example 3 - Refresh all FXLData functions in the current sheet

Public Sub myMacro()
   FXLDataRefreshSheet
End Sub

Macro Example 4 - Refresh the FXLData function in the specified cell

Public Sub myMacro()
   FXLDataRefreshCell Range("C4")
End Sub

Dimension at Observation

For horizontal presentation functions, the dimension at observation defaults to time but can be changed using the dimensionAtObservation REST argument.

REST Argument Syntax
dimensionAtObservation=<DIMENSION_ID> | AllDimensions

Behaviour

Value	Behaviour	Example
<DIMENSION_ID>	Using the ID of any other dimension in the dataset will cause the observations to be broken down by that dimension which will appear across the columns	dimensionAtObservation=REF_AREA
TIME_PERIOD	The same as the default behaviour where time is the dimension at observation	(dimensionAtObservation argument is ommitted)
AllDimensions	Setting the dimension at observation to the special value AllDimensions generates a result set with a single row per observation	dimensionAtObservation=AllDimensions

Examples
Setting REF_AREA as the dimension at observation

=FXLDataUrl("https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/WB,GCI,1.0/GBR?labels=id&round=1&dimensionAtObservation=REF_AREA")

AllDimensions - the result is precisely one observation per row

=FXLDataUrl("https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/WB,GCI,1.0/GBR?labels=id&round=1&dimensionAtObservation=AllDimensions")

Default behaviour with time as the dimension at observation

=FXLDataUrl("https://demo.metadatatechnology.com/FusionRegistry/ws/public/sdmxapi/rest/data/WB,GCI,1.0/GBR?labels=id&round=1")

Choosing Attributes to Include in the Resultset

A breakdown of some or all series attributes can be returned as part of the resultset if required. Note that dataset and observation-level attributes are not available.

Include all attributes

• =FXLData() horizontal presentation: set includeBreakdown=TRUE and includeAttributes=TRUE
  
• =FXLDataV() vertical presentation: set labels=both and includeAttributes=TRUE

Include selected attributes

• Set includeBreakdown=TRUE for =FXLData() or labels=both for =FXLDataV()
  
• Add to the REST Args: attributes= followed by a comma-separated list of the attribute IDs to include. e.g. attributes=UNIT,TITLE

Worked examples

The following are samples from the ECB's EXR (Exchange Rates) dataset:

Include all attributes using horizontal presentation.

=FXLData("https://demo.metadatatechnology.com/FusionRegistry","EXR","A",100,,"1990","1995","id",True,True,True,True)

Include all attributes using vertical presentation.

=FXLDataV("https://demo.metadatatechnology.com/FusionRegistry","EXR","A",100,,"1990","1995","both",True,True,True,True)

Include just the UNIT and TITLE attributes using horizontal presentation.

=FXLData("https://demo.metadatatechnology.com/FusionRegistry","EXR","A",100,"attributes=UNIT,TITLE","1990","1995","id",True,True,True,True)

Include just the UNIT and TITLE attributes using vertical presentation.

=FXLDataV("https://demo.metadatatechnology.com/FusionRegistry","EXR","A",100,"attributes=UNIT,TITLE","1990","1995","both",True,True,True,True)

Fusion Registry Authentication

Excel will automatically request the user to authenticate when executing and FXLData function where the Fusion Registry data source is operating in private mode.

Points to note:

• Excel will remember authentication details provided for the remainder of the session. Close and reopen Excel if you need to re-authenticate as a different user.
• A spread sheet can contain multiple FXLData functions using different Fusion Registries. Excel will ask for separate authentication details for each Fusion Registry, thus it is possible to connect to Fusion Registry A as user X, and Fusion Registry B as user Y.
• No authentication will be requested if a Fusion Registry is operating in public mode.

There is no way to force FXLData to authenticate as a particular user if the Fusion Registry is operating in public mode but also allows authenticated users with additional data access privileges. Fusion Registry administrators should consider switching to private mode as a work-around.

[username]@ URL prefix to force authentication as a specific user

From Fusion Registry 11.1.1 (release 10 June 2022) and FXLData 1.1.1, [username]@ can be prefixed to the URL to force authentication as the user identified by [username].

Example:

=FXLData("johnwright@https://stats.mydomain.org/FusionRegistry","ABC,CPI,1.0","A..X00.M+Q._Z")

The Fusion Registry will ensure the user logs in with the given username. To force authentication without specifying a username, user the @ prefix with no username.

=FXLData("@https://stats.mydomain.org/FusionRegistry","ABC,CPI,1.0","A..X00.M+Q._Z")

Resultset Metrics

Metrics are shown in the first row of the result set if headers are enabled.

Example Metrics

Series Count

100/3608 series

<base series retrieved>/<base series available> series

• <base series retrieved> is the number of base series retrieved before any calculated measures are added or aggregations performed.
  
• <base series available> is the total number of base series available for the query.

The effect of calculated measures

If the query includes calculated measures such as percentage change or moving average, the actual number of series retrieved will be higher than the reported base series. The actual number of series in the result set can generally be calculated as:

<base series retrieved> * (1 + <number of calculated measures>)

Note that this formula does not hold true when combining aggregations with calculated measures.

The effect of aggregations

Aggregations reduce the number of series retrieved due to the removal of one or more dimensions. Thus, the series retrieved will be lower than the reported base series.

Function Execution Time

0.29 seconds

<execution time> seconds

The actual time the function took to retrieve the data from the Fusion Registry and return the result set to Excel.

Resultset freshness timestamp

18/11/2021 17:10:07

<date time>

The date and time the resultset was last refreshed from the Fusion Registry data source.

Controlling when metrics are displayed

For parameterised functions (=FXLData() and =FXLDataV()), metrics are displayed when the IncludeHeader argument is TRUE. Set to FALSE to omit metrics.
For URL functions (=FXLDataUrl() and =FXLDataUrlV()), metrics are displayed if the REST API parameter excludeHeader=false. Set the parameter to excludeHeader=true to omit metrics.

Troubleshooting

The FXLData addin disappears or fails to load

A possible cause is Windows file protection security settings blocking the FXLData.xlam file as it has originated from another computer. The following YouTube video explains how to solve the problem by disabling Windows protection on the file: https://www.youtube.com/watch?v=AhnOU-ulqNg

This article from microsoft also explains the process to unblock a macro:
