ChatGPT

ChatGPT with Advanced Data Analysis can actually run Python on your uploaded spreadsheet and verify the formula works — not just guess at it. For pure formula generation, it also gets edge cases (date formats, exact text matching) right more often than competitors.

Prompt template
I have a spreadsheet with these columns:
A: [COLUMN A DESCRIPTION]
B: [COLUMN B DESCRIPTION]
C: [COLUMN C DESCRIPTION]
[add more as needed]

I need a formula in cell [TARGET CELL] that calculates: [WHAT YOU WANT].

Give me:
1. The formula
2. A 1-sentence explanation of how it works
3. An alternative approach if there is one
4. Common gotchas to watch for (date formats, exact text matching, blanks)

Excellent at formula generation and the clearest explanations of what each part of a complex formula does. Best when you want to learn, not just copy-paste. Cannot execute formulas to verify them.

Frequently asked

  • Can ChatGPT write VBA macros for Excel?

    Yes, and it does this well. Claude's VBA explanations are slightly clearer, but ChatGPT's are more likely to run on the first try.

  • Should I just use Microsoft Copilot in Excel instead?

    Copilot ($30/user/month) is convenient if you already have an M365 enterprise license, but it can't process AI prompts row-by-row across thousands of rows. ChatGPT/Claude give you more control for one-off complex formulas.

  • Why does my AI-generated formula sometimes return #N/A or #VALUE!?

    Almost always either (1) the date column is stored as text not a date, or (2) text values have invisible spaces. Tell the AI what error you got and paste a sample row — it will fix it.
