The job to be done
How does Diff Anything help with spreadsheet handoff and migration?
Compare stored cell values when a workbook moves between Excel, OpenDocument, Apple Numbers, CSV, or TSV formats without converting both files first.
Folder comparison provides two-pane tree and table layouts, global search and filtering, progressive loading, semantic nested-file comparison, moved-file detection, and ignore patterns. Archive mode compares normalized paths and streamed SHA-256 hashes across ZIP/ZIP64/ZIPX, 7z, RAR, TAR families, and standalone compressed streams, including encrypted and supported multipart sets. Pro turns reviewed folder changes into explicit create, update, delete, and move plans with stale-result protection, progress, cancellation, metadata preservation, durable recovery, rollback, and one-click undo.
Recommended path
Select a mode
Use automatic detection or explicitly choose text, structured, cross-format spreadsheet, folder, archive, document, image, binary, or API comparison. Archive detection can recognize supported container signatures even when the filename is misleading.
Diff Anything keeps the source pair, selected mode, comparison rules, result, and review state together so the same decision can be revisited or automated.

How does Diff Anything help with spreadsheet handoff and migration?
Compare stored cell values when a workbook moves between Excel, OpenDocument, Apple Numbers, CSV, or TSV formats without converting both files first. The recommended path starts with select a mode and uses cross-format spreadsheet comparison, document and binary inspection, local review workspace.
Do compared files leave the computer?
No. Comparison is local. The application has no account, cloud comparison service, analytics, or telemetry.
How does automatic mode choose a comparison?
Compatible spreadsheet formats can use the shared stored-value comparison even when their extensions differ, matching structured formats use their semantic engine, two folders use folder comparison, and other compatible inputs fall back to text. You can always choose a concrete mode.
