FXLData

An Excel addin providing a collection of functions for retrieving statistical data from a Fusion Registry directly into a worksheet.

Overview

The FXLData family of functions work like normal Excel formulas with the exception that the result is an array of series and observation values spanning multiple rows and columns. This behaviour differs from functions such as =sum() and =average() that return a single value into the cell containing the formula. Microsoft's documentation provides general information on how that these array formulas work.

Functions horizontal (time-series) presentation

Returns a selected dataset in time-series format with one series per row

Horizontal time-series example

=FXLData()

• The function has 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

Examples

=FXLData("https://demo.metadatatechnology.com/FusionRegistry","ECB,EXR,1.0","A...")
=FXLData("https://demo.metadatatechnology.com/FusionRegistry","ECB,EXR,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)

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

=FXLDataUrl()

• Behaves the same 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

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

Functions for vertical presentation

Returns a selected dataset with one series per column and time on the rows.

Vertical example

=FXLDataV()

• Like its horizontal counterpart, FXLDataV has three mandatory arguments: the base URL of the Fusion Registry, the Dataflow, a Series Key pattern specifying what series to return
• There are a further seven optional arguments for controlling: the maximum number of series to retrieve, start / end period, labels, header behaviour and whether attributes are shown
• REST API data query arguments can also be given for special operations like number precision and calculated measures (e.g. % change)

Examples

=FXLDataV("https://demo.metadatatechnology.com/FusionRegistry","ECB,EXR,1.0","A...")
=FXLDataV("https://demo.metadatatechnology.com/FusionRegistry","ECB,EXR,1.0","A...",1000,"calculatemeasure=CALC_MEASURE;pch;mvavg,3",2010,2020,id,false,false)
=FXLDataV(C13,C3,C6,C14,C12,C4,C5,C11,C8,C10)

=FXLDataUrlV()

• Behaves the same 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

Examples

=FXLDataUrlV("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)

Administrative functions

=FXLDataVersion()

• Returns the software version number

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, more information on how to do this is given in the 'Dimension at Observation behaviour' paragraph below.

Use Case
This parameterised form is suitable for hand 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","EXR","all")

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

Syntax
=FXLData( RegUrl , Dataflow , Expression , [MaxSeries] , [RestArguments] , [StartPeriod] , [EndPeriod] , [Labels] , [IncludeHeader] , [IncludeSeriesKey] , [IncludeBreakdown] , [IncludeAttributes] )

	Argument	Description	Examples	Required?
1	RegUrl	The base URL of the Fusion Registry service	https://demo.metadatatechnology.com/FusionRegistry	Mandatory
2	Dataflow	The Dataflow to query conforming to the SDMX REST specification for data queries	ECB,EXR,1.0	Mandatory
3	Expression	A series key pattern defining the series to select	A.CAD+HUF+INR...E	Mandatory
4	MaxSeries	The maximum number of series to return	1000	Optional Defaults to 100 series
5	RestArguments	Additional data REST query arguments intended for special use cases like adding calculated measures or changing the dimension at observation	round=3&calculatemeasure=THE_MEASURE;pch;mvavg,3&dimensionAtObservation=CURRENCY_DENOM	Optional
6	StartPeriod	The start period in SDMX standard time format	2010-06-12 2010	Optional Defaults to the start of the available data
7	EndPeriod	The end period in SDMX standard time format	2010-06-12 2010	Optional Defaults to the end of the available data
8	Labels	Component labels id - IDs only name - names only both - both IDs and names	both	Optional Defaults to id
9	IncludeHeader	Boolean TRUE includes component labels at the head of each column and shows metrics FALSE component labels and metrics are ommitted	FALSE	Optional Defaults to TRUE
10	IncludeSeriesKey	Boolean TRUE adds a calculated dimension 'series' with the series key as the value FALSE series keys are not included in the dataset	FALSE	Optional Defaults to TRUE
11	IncludeBreakdown	Boolean TRUE includes dimensions FALSE excludes dimensions	FALSE	Optional Defaults to TRUE
12	IncludeAttributes	Boolean TRUE includes dataset and series-level attributes FALSE excludes attributes	FALSE	Optional Defaults to TRUE

=FXLDataUrl()

By default ƒ_x =FXLDataUrl() returns a horizontal time-series dataset. Time is the dimension at observation by default resulting in one series per row with time periods spanning the columns. A different dimension at observation can be chosen, more information on how to do this is given in the 'Dimension at Observation behaviour' paragraph below.

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
=FXLDataUrl( 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
2	MaxSeries	The maximum number of series to return	1000	Optional Defaults to 100 series
