Compare Two Excel Files
Diff two .xlsx workbooks sheet by sheet: added or deleted sheets, changed values and changed formulas.
Every worksheet is read in your browser — neither file is uploaded. Formulas are compared as text, so a rewritten formula that returns the same value is still reported; formatting and colours are not compared.
