Excel & Google Sheets Formula Generator

Describe what you want in plain English and get the exact Excel or Google Sheets formula — explained part by part, with pitfalls and an alternative approach.

The Prompt — replace [BRACKETS] with your details

Act as a spreadsheet expert. Write a formula for [EXCEL / GOOGLE SHEETS].

My sheet:
- Columns: [DESCRIBE, e.g., "A = order date, B = region, C = amount"]
- Example rows: [PASTE 2-3 SAMPLE ROWS IF POSSIBLE]

What I want the formula to do: [PLAIN-ENGLISH GOAL, e.g., "sum column C for the region in E1, but only orders from the last 30 days"]

Give me:
1. The exact formula, ready to paste
2. A part-by-part explanation in plain English
3. The most likely reason it could break (blank cells, text vs. numbers, date formats) and how to make it robust
4. One alternative approach (helper column, pivot table, or newer function like FILTER/XLOOKUP) and when it's the better choice

How to use this prompt

Show sample rows — most formula failures come from the AI guessing your layout.
Say which app AND version; older Excel lacks FILTER, XLOOKUP, and LET.
Test on a copy of your sheet before replacing a working formula.
