Draft a spreadsheet formula with check cases
Translate a specific sheet requirement into a formula and a small set of examples you can verify.
Start with these inputs
- Spreadsheet app and locale
- Column letters, sample rows, and expected results
- Rules for blanks, errors, and duplicates
Follow the workflow
- Make a copy of the sheet and prepare a small sample with known answers.
- Paste the app, locale, columns, and rule into ChatGPT.
- Check the proposed functions against your spreadsheet app’s documentation.
- Try the formula on the sample copy and verify every check case before applying it more broadly.
Your starting prompt
Help me draft a formula for [spreadsheet app and locale]. Goal: [plain-English requirement] Columns and sample rows: [paste] Rules for blanks/errors/duplicates: [rules] Return a formula using my exact ranges, a plain-English explanation, and five check cases including a blank and an edge case. State any function/version assumptions. Do not claim the formula was executed. If the requirement is ambiguous, ask before choosing a rule. Do not modify a live sheet.
What the output could look like
Illustrative example, not a recorded test result.
Illustrative example using invented sample inputs:
Illustrative requirement: add amounts in B2:B10 only when A2:A10 says “Approved.”
Formula draft: =SUMIF(A2:A10,"Approved",B2:B10)
Check case: a blank status should not contribute to the total. Not executed here.
Review before you use it.
The AI drafting step has a free option; your spreadsheet app may have its own plan requirements. A formula can look correct and still mishandle locale, ranges, or blanks. Verify it in your actual spreadsheet app before relying on the result. Time is an approximate planning estimate, not a measured result. Free access has usage limits; features can vary by account.
