You do not need to memorize syntax to write a good Excel formula. The trick is describing what you want in plain words, with the right ranges, and letting the model turn it into something you can paste. That is exactly what these five prompts do. Fill in the table, run the prompt that matches your task, and paste the result into the cell.
Before you start: the variables
| [Variable] | What to fill in |
|---|---|
| [goal] | What you want the formula to produce, in one plain sentence. |
| [data range] | The columns and rows involved, such as A2:A500 or the table name. |
| [criteria] | The condition the formula must match, such as a status or a date range. |
| [target cell] | Where the result should appear. |
| [Excel version] | Which version you use, so the formula avoids unsupported functions. |
The prompts
1. Write a formula from a goal
Write an Excel formula for [goal]. The data lives in [data range], and the condition is [criteria]. Use functions supported in [Excel version]. Give me the formula on its own line, then explain what each part does in one line.What it does: Converts a plain-language goal into a formula you can paste without guessing at the syntax.
How to use: replace [goal], [data range], [criteria], and [Excel version]; keep the rest as is.
2. Explain a formula you inherited
Explain this Excel formula in plain English: [formula]. Walk through it from the inside out, state what it returns, and flag any part that will break if the data changes, such as [data range] gaining rows.What it does: Turns a dense inherited formula into something you can safely edit.
How to use: paste the formula into [formula] and name the range in [data range]; keep the rest as is.
3. Debug a wrong result
This Excel formula returns the wrong result: [formula]. It should produce [expected result], but it shows [actual result]. The data is in [data range]. Identify the most likely cause, then give me a corrected formula and one line on why it works.What it does: Finds the reason a formula is off instead of you testing changes one by one.
How to use: replace [formula], [expected result], [actual result], and [data range]; keep the rest as is.
4. Turn a manual process into a formula
Right now I do this by hand every week: [manual steps]. The data sits in [data range]. Turn it into a single Excel formula that works in [Excel version], and point out any step that cannot be automated without a helper column.What it does: Automates the repetitive copy-and-check work you keep doing by hand.
How to use: describe the steps in [manual steps] and set [data range] and [Excel version]; keep the rest as is.
5. Look up a value safely
Write an Excel formula that finds the value matching [criteria] in [data range] and returns it to [target cell]. The lookup key may be missing sometimes. Handle the not-found case so the cell stays clean instead of showing an error. Explain the fallback in one line.What it does: Builds a lookup that fails gracefully instead of filling your sheet with errors.
How to use: replace [criteria], [data range], and [target cell]; keep the rest as is.
A quick worked example
Take prompt 1. Suppose [goal] is “sum the order totals for one sales rep,” [data range] is A2:D500 where column B holds the rep name and column D holds totals, [criteria] is “rep name equals the value in G2,” and [Excel version] is Microsoft 365.
The model returns:
=SUMIF(B2:B500, G2, D2:D500)
It then explains that B2:B500 is the range to check, G2 is the rep to match, and D2:D500 is what gets summed. Paste it into your target cell and the total appears.
