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 useful background information on how that these array formulas work.
The addin provides four separate formulas that all retrieve selected data but in slightly different ways.
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)
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)
=FXLData()
Arguments
| Argument | Description | Examples | Required? |
|---|---|---|---|
| RegUrl | The base URL of the Fusion Registry service | https://demo.metadatatechnology.com/FusionRegistry | Mandatory |
| Dataflow | The Dataflow to query conforming to the SDMX REST specification for data queries | ECB,EXR,1.0 | Mandatory |
| Expression | A series key pattern defining the series to select | A.CAD+HUF+INR...E | Mandatory |
| MaxSeries | The maximum number of series to return | 1000 | Optional - defaults to 100 series |
| RestArguments | Additional data REST query arguments intended for special use cases like adding calculated measures | round=3&calculatemeasure=THE_MEASURE;pch;mvavg,3&dimensionAtObservation=CURRENCY_DENOM | Optional |
| StartPeriod | The start period in SDMX standard time format | 2010-06-12 for daily, 2010 for annual | Optional - defaults to the start of the available data |
| EndPeriod | The end period in SDMX standard time format | 2010-06-12 for daily, 2010 for annual | Optional - defaults to the end of the available data |
| Labels | Example | Example | |
| IncludeHeader | Example | Example | |
| IncludeSeriesKey | Example | Example | |
| IncludeBreakdown | Example | Example | |
| IncludeAttributes | Example | Example | |
