Excel functions scare a lot of people: is VLOOKUP’s fourth argument 0 or 1? How do those three layers of IF brackets even line up? You end up digging through tutorials just to compute one small thing.
But you don’t actually need to memorize functions. What you want isn’t “to learn formulas” — it’s “to get this number.” Describe your sheet and the result in plain language, and AI hands you a formula you can paste straight into a cell, plus where to put it and how to fill down. Let AI carry the burden of remembering syntax.
When to use it
Can’t remember VLOOKUP, nested IFs or SUMIF? Skip learning them — describe the need and AI gives the formula plus how to fill and drag it.
How to do it
- Open Doubao or DeepSeek
- Describe your sheet: what each column (A/B/C) holds
- Say what result you want and which column it goes in
- Paste the formula it gives and swap the column letters to match yours
- If it errors, send the error text or a screenshot back and ask it to fix
Weak vs strong
On the left AI can only guess; on the right — once it knows each column and where the result goes — it returns a precise, ready SUMIF.
Copy-paste prompt
I’m using Excel. My sheet: column A is [name], B is [dept], C is [amount]. I want: [sum amount by department in column E]. Give me a paste-ready formula, say which cell to put it in and how to fill down, and a simpler alternative if there is one.
Worked examples
You get：You get a VLOOKUP (or the sturdier XLOOKUP) with each argument explained — what to look up, where, which column to return, exact match or not — and you just plug in your column letters.
You get：It returns a nested IF (or the cleaner IFS) with brackets already balanced; drag it down and every row is graded — no counting parentheses.
Level up
- Don’t get it? Ask it to “break this formula into parts and explain each in plain words” — you learn as you go
- Reverse it: paste a confusing old formula and ask “what does this compute?” — great for inheriting someone’s sheet
- Ask for the easier route: some tasks are faster with a pivot table than a formula — ask which fits
Common mistakes
- Not mapping columns — always say what A/B/C hold, or the column references will be wrong
- Not naming your app — Excel, WPS and Google Sheets differ slightly; one line saves rework
- Giving up on an error — paste the error back; it’s usually a column or full-width-bracket slip it fixes instantly
FAQ
My data is confidential — is it safe to paste my sheet?
Will I have to edit the formula it gives?
Pro tip：Keep a small “formula cheat sheet” of your common ones (sum, lookup, grading) and reuse them — far easier than memorizing functions.
