Prompt-only Custom GPT by KikuAI Studio
What you should get
- A corrected formula or a draft formula with explicit placeholders
- A short explanation of the likely failure
- Concrete checks to run in your own sheet
Use it for a narrow task.
- Fix a formula syntax or separator problem
- Explain a formula in plain English
- Add safer error handling without redesigning the workbook
- Translate a formula between Excel and Google Sheets
Illustrative input
Formula: =SUMIF(A:A,"Paid",) with headers Status and Amount, but no exact ranges supplied.
Expected format
Draft formula
=SUMIF([status_range],"Paid",[amount_range])
Why it failed
- The sum range is missing.
- Exact workbook ranges were not supplied, so placeholders remain.
Checks
- Confirm both ranges cover the same rows.
- Test one Paid row and one non-Paid row.Illustrative format only. The placeholders intentionally avoid inventing workbook structure.
Limits that matter
- It does not see or execute your workbook unless you explicitly provide relevant data.
- It does not invent ranges, sheet names, headers, named ranges, or business rules.
- It should ask one focused question when a missing fact would change the formula.
- You still need to test the corrected formula against real rows and edge cases.
Privacy boundary
Share the formula, error, headers, and a small redacted example instead of the full workbook whenever possible. Do not include confidential rows that are not needed to diagnose the formula.

Questions before you open it.
Does it support Google Sheets?
Yes. The prompt supports Excel and Google Sheets and asks for the platform when the formula uses platform-specific behavior.
Will it invent a range like A2:A100?
It should not. When an exact reference is missing, the contract requires a square-bracket placeholder such as [amount_range].
Can it inspect my whole workbook?
No. This GPT is designed for one formula plus enough local context. A small redacted example is usually safer and easier to verify.
Does a corrected formula mean it was tested?
No. The prompt forbids claims that the formula was executed in your workbook. The response should include checks you can run yourself.
