Popular questions

More answers in our help center

Does this audit every Excel feature?

This workflow focuses on records and values. Tell Air9 if formulas or particular sheets matter, and review the result. It is not a promise of complete macro, formatting or workbook-feature auditing

What if rows moved between versions?

Records are matched by the key you choose, so reordering, sorting and inserted rows do not produce false differences

What happens after I click start?

You open a screen for this task, where you can add files, write what you need or try an example before sending

Will the AI fill in missing facts?

Tell Air9 which facts to use and ask it to flag anything missing. Check important values and commitments against your sources before using the result
