You can export your project's inputs, constants, and formulas to an Excel file for review or record-keeping. This article covers what the export contains and what it's for.
How to download
In the formula data view, click the Download as Excel icon (the download arrow). Numio generates a file named formula-data.xlsx and saves it to your computer.
What's in the file
The export lays everything out on a single sheet, grouped into columns:
| Column | Contents |
|---|---|
| Input Type | The block type of each user input (for example inputField, slider) |
| Input Title | The label of each input block |
| Input Value | Left blank — this is the cell your end-user fills in |
| Constant Title | The name of each constant |
| Constant Value | The constant's value |
| Formula Title | The name of each formula |
| Formula | The formula expression, written as an Excel formula |
Inputs, constants, and formulas are each placed so their title sits next to their value, mirroring how they're organized in the editor.
It's a snapshot, not a backup
The download is informational. It's meant for reviewing your math outside Numio, sharing it with a colleague, or keeping a record of how a calculator is built.
It is not re-importable — there's no way to load formula-data.xlsx back in to rebuild your project's inputs, constants, and formulas. (Importing a spreadsheet brings cell data into the Formula tab; it does not restore the input/constant/formula structure this file describes.)
