Diff AnythingFile and folder comparison for Mac and Windows

No. Comparison is local. The application has no account, cloud comparison service, analytics, or telemetry.

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.

Yes. Diff Anything compares stored cell values by sheet and coordinate across Excel, OpenDocument, and Apple Numbers workbooks in any pairing. A CSV or TSV file opened beside a workbook is compared by cell values with one sheet, the first by default; choose another under Compare with sheet. Values are compared as stored text, so 20 and 20.0 count as different. Formulas, formatting, charts, macros, and workbook layout are not compared.

Yes, with the Microsoft Store version on Windows. The CLI supports difference exit codes, machine-readable output, Git difftool configuration, and a Git diff driver for file types you assign in .gitattributes. The free CLI compares text and JSON; Pro adds every other CLI mode, batch manifests with JSON, JUnit, or SARIF output, and --fail-on breaking for API schema checks.

Three-way merge is part of Pro. Choose a common Base for Ours and Theirs. Focused source diffs show what each side changed from Base, and independent line edits, or edits to separate words of the same line, combine automatically. When both sides change the same words, the result is a conflict; a value is never assembled from parts of each side. Overlapping edits offer Ours, Theirs, Ours then Theirs, Theirs then Ours, and Base choices, with conflict navigation, bulk side choices, and reset. The result remains editable and cannot become the current right source while conflict markers remain; saving that modified source is a separate action.

Yes. Pro folder synchronization previews create, update, delete, and move actions, rejects stale plans, applies the reviewed selection transactionally with progress and cancellation, preserves supported metadata, uses durable recovery journals and restart-safe rollback, and offers one-click undo after a successful synchronization.

ZIP/ZIP64 and ZIPX, ZIP-based packages, 7z, RAR 1.3 through 7, TAR and compressed TAR variants, plus standalone Gzip, Bzip2, XZ, and Zstandard streams. Encrypted ZIP, 7z, and RAR archives are supported, as are numbered 7z and common RAR volume sets. Split ZIP, ACE, ARJ, CAB, ISO/disk images, and filesystem images are not archive-mode inputs.

Selected text, JSON, YAML, XML, environment-file, HTTP-response, and API-schema differences can be applied in either direction. JSON and HTTP targets are edited in place, so their comments, trailing commas, indentation, and layout are kept. YAML and XML targets are rewritten from their parsed data after a confirmation, which drops comments and custom layout. A JSON API schema keeps its layout; a YAML schema is rewritten after a confirmation.

Yes. In Settings → Difference colors, choose Blue and yellow. Additions become blue and removals yellow, in light and dark themes. Written difference descriptions provide another way to check what changed. The setting is part of the free plan.

Yes. The accessible workspace (Command-Shift-A on a Mac, Control-Shift-A on Windows) lists every difference in words with its location and both values, and lets you review, ignore, and apply changes from the keyboard. On a Mac it opens automatically when VoiceOver is running.
