How to use the Excel Formula Generator

- Pick Excel or Google Sheets and describe your columns.
- Click Generate Prompt and run it in ChatGPT, Claude or Gemini.
- Paste the formula into a cell and check the result before relying on it.
Stop fighting with formula syntax
Nested IFs, XLOOKUP, SUMIFS, array formulas — the logic is simple but the syntax is fiddly. This generator builds a prompt that gives the AI the two things it needs to get the formula right the first time: exactly what you want to calculate, and how your sheet is laid out. The result maps to your real columns instead of made-up ranges.
It works for Excel and Google Sheets, from quick SUMIFS and VLOOKUP fixes to trickier text parsing, date math and conditional aggregations.
Always check the result
AI formulas are a fast starting point, not gospel. Paste the formula into a spare cell, test it against a few rows you can verify by hand, and confirm the edge cases — blanks, errors, zero vs empty — behave the way you expect before you build a report on top of it.
