An Excel addin providing a collection of functions for retrieving statistical data from a Fusion Registry directly into a worksheet.
Contents
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
=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.
=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 ƒx =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] )

3 | Expression | A series key pattern defining the series to select | A.CAD+HUF+INR...E | Mandatory |

=FXLDataUrl()
By default ƒx =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
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 |
=FXLDataV()
By default ƒx =FXLDataV() returns a vertical dataset, one series per column with time spanning the rows. The dimension at observation cannot be changed, the REST argument, if set is ignored.
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:
