WorkbookDiff

WorkbookDiff helps analysts and spreadsheet reviewers compare two same-layout .xlsx workbook versions in their browser. Workbook files stay on the device. Free comparison and CSV export cover cell values, stored formula expressions, added or removed worksheets, worksheet visibility, hidden rows and columns, and used-range differences. An optional $19 one-time handoff report adds review marks, notes, HTML export and printing for one workbook pair, with repeat exports of the same report. No subscription is required. Comparison is coordinate-based: it does not realign reordered rows, recalculate formulas, or compare formatting, charts, pivots or macros. Inputs are two unencrypted .xlsx files, up to 20 MiB each.
