FXLDataLookup and FXLDataPeriod Functions

Introduced in H1.3.0.03 (January 2026).

Fusion XL Data - FXLDataLookup and FXLDataPeriod Formulas

Context

To date, FXLData has been used primarily to generate data cubes in Excel from a Fusion Registry by applying user‑defined selection criteria. The add‑in issues SDMX REST queries to the Fusion Registry and renders the results as a structured grid, typically one series per row (time across columns) or one series per column, so analysts can work with a familiar worksheet layout.

Problem

The current workflow is geared to building full grids/cubes from Fusion Registry; getting a single value or a small ad‑hoc slice often means running a broader query and then indexing/filtering the filled grid, which adds unnecessary steps for simple asks.

Solution

2 New Formulas have been introduced:

• FXLDataLookup retrieves targeted measures directly from an existing root grid, returning a single value, short list, or small table. It also supports simple arithmetic, period wildcards, optional auto‑refresh, and explicit error messages.
• FXLDataPeriod returns the minimum and/or maximum SDMX periods found on a specified root grid so lookups can use dataset bounds without manual date handling (with sheet‑not‑found error handling).

FXLDataLookup Formula

FXLDataLookup reads values from an existing root grid on a specified worksheet and returns the measures for the given series key(s) and period(s) as a

• single value
• short list
• or small table

depending on how many items and periods you pass.

Syntax

FXLDataLookup(items, periods, sheetName, [autoRefresh], [errorMessages])

Parameters

items

• A single series key (text)
• a range of keys
• or an expression combining series keys and numbers with supported operators.

periods

• A single period
• a range of periods
• a wildcard (e.g., "2001*")

sheetName - The worksheet containing the root grid with the expected header/layout [autoRefresh]

• OPTIONAL, Defaults to FALSE
• TRUE/FALSE. When TRUE, forces updates only if Excel is not in automatic calculation mode.

[errorMessages]

• OPTIONAL, Defaults to FALSE
• TRUE/FALSE. When TRUE, returns descriptive messages (e.g., “Key Not Found”, “Non‑numeric Value”, “Divide By Zero”, “Invalid Power”, “Parse Error”).

Supported Operators - items parameter

Arithmetic

• + (add)
• - (subtract)
• * (multiply)
• / (divide)
• ^ (power)
• Standard arithmetic precedence applies;
• parentheses can be used to control evaluation order

Unary signs:

• leading -
• and + are supported

Exponent constraint: for ^, the right‑hand exponent must be numeric, either a literal or a cell reference to a numeric value; using a series key on the right‑hand side raises Invalid Power. The left‑hand/base may be a series key.
