Does the formula generator work in the browser?

Yes. Your workbook is parsed locally in the browser and never uploaded to the server.

Can it use values from my uploaded workbook?

Yes. The generator picks a sheet column and creates a formula range from your workbook data.

Can I switch to the full Excel tools hub?

Yes. You can open the full hub if you want the other Excel utilities in one place.

How the Excel hub works

One workbook powers multiple Excel utilities in the same session.

Switch tabs to convert, clean, extract columns, merge sheets, or find duplicates.
Download the result you need without re-uploading the same file.

The hub can absorb more tools without changing the upload flow.

Workbook-aware formula creation

This page uses the same workbook engine as the Excel hub, but it opens directly on the formula generator so the path to a usable formula is faster and more focused.

What you can do here

Upload .xlsx and .xls files locally in your browser.
Choose a sheet column for the formula range.
Generate, explain, and validate formulas in one place.
Jump back to the full Excel hub whenever you need the rest of the tools.
