Problem solved by Diff Anything
Compare stored cell values across different spreadsheet formats locally, including XLSX with ODS or Apple Numbers.

The problem
A workbook can move between Excel, LibreOffice, Apple Numbers, CSV, and TSV during a handoff or migration. Converting both files to one format adds another transformation and a line diff exposes container noise instead of answering whether the stored data changed.
The solution
Diff Anything normalizes sheets and populated cell coordinates across CSV, TSV, XLS/XLA, XLSX/XLSM/XLAM, XLSB, ODS, and Apple Numbers. The two formats can differ. A sheet-aware grid connects changed cells with the Differences pane while the files remain on the computer.
01 / Cross-format comparison
Compare CSV, TSV, XLS/XLA, XLSX/XLSM/XLAM, XLSB, ODS, and Apple Numbers in any supported pairing. Examples include XLSX against ODS, Numbers against XLSX, or a workbook against a delimited export.
Sheets and cell coordinates provide the shared model, so unrelated workbook container structures do not become the result.
02 / Cross-format comparison
Choose a sheet and scan two aligned grids with row numbers and column letters. Selecting a changed cell connects its coordinate to the Differences pane.
Populated rows and columns are virtualized to keep large ranges navigable.
03 / Cross-format comparison
Diff Anything compares stored cell values. It does not compare formulas, formatting, charts, macros, or workbook layout.
A clean value comparison is useful evidence for a data handoff, but it does not prove that calculation logic, styling, automation, print setup, or editing behavior survived the format change.
Clear answers
Yes. Diff Anything supports mixed-format spreadsheet pairs and compares their stored values by sheet and cell coordinate.
No. It means the compared stored cell values are equivalent under this mode. Formulas, formatting, charts, macros, and workbook layout are not compared.
Yes. The files are extracted and compared locally; Diff Anything has no account, cloud comparison service, analytics, or telemetry.
Three short steps
Open any two supported spreadsheet files.
Choose a sheet and inspect the aligned values.
Select changed cells and verify excluded workbook properties separately when they matter.
