Ask Flex / Excel and AI

Ask Flex

Can AI do Excel formulas?

Yes. Test one row.

What you type

"I need a formula to add up sales."

"Column A is the rep's name. Column C is the sale. Add up the sales for the name in E2."

What you get back

"A formula for somebody else's sheet. It errors in yours."

"=SUMIF(A:A,E2,C:C), and one line on what each part does."

An example. Your sheet, your columns.

Flex's short answer

Yes, and it's one of the things AI is best at, as long as you tell it what's in your columns. Test the formula on one row you can check by hand before you trust it on the whole sheet.

✱ Flex's tips

Name your columns first.

1

Name your columns

The letter, then what's in it.

2

Say it in plain words

"Add up the amounts for each name."

3

Test one row by hand

If the math matches, fill it down.

4

Paste the error back

"It says #N/A." It'll fix its own work.

Try this in your own Claude or ChatGPT

Write me an Excel formula. My columns: [list each column letter and what's in it]. What I want: [say it in plain words]. Tell me which cell to put it in, explain each part in one line, and tell me one way to check it's right.

Before you paste work stuff into any AI, check what your company allows.
