The problem
Why the usual workflow gets in the way.
Financial exports, customer lists, research data, and internal reports may be inappropriate for a browser upload. A line diff is also a poor fit for workbook containers because it cannot present stored values as sheets, rows, columns, and cells.
The solution
How Diff Anything handles it.
Diff Anything extracts supported spreadsheets on the computer, aligns populated cells by sheet and coordinate, and connects changed cells to a Differences pane. It compares stored cell values; formulas, formatting, charts, macros, and workbook layout remain outside the result.
01 / Private spreadsheet review
Define what the comparison can prove
This workflow answers whether stored cell values differ by sheet and coordinate. It does not compare formulas, formatting, charts, macros, workbook layout, print settings, or editing behavior.
A clean value comparison is useful evidence for a data handoff, but it does not prove that two workbook files are otherwise identical.
- Use the grid for stored values.
- Review formulas separately when calculation logic matters.
- Review formatting and workbook features in their native editor.
02 / Private spreadsheet review
Keep the workbook structure visible
Choose a sheet, then review aligned rows and columns with familiar cell coordinates. Selecting a changed cell connects the grid position to the Differences pane instead of reducing the workbook to archive internals.
Diff Anything supports Excel (XLS, XLSX, XLSM, XLSB, and their templates), OpenDocument (ODS), and Apple Numbers workbooks, including mixed-format pairs when a handoff crosses spreadsheet applications. You can also open a CSV or TSV export beside the workbook to check it against the sheet it came from.
03 / Private spreadsheet review
Keep the files on the computer
Spreadsheet extraction and comparison run locally on macOS and Windows. Diff Anything has no account, cloud comparison service, analytics, or telemetry.
Signed store builds may separately contact the Mac App Store or Microsoft Store for product, purchase, and entitlement checks. The workbooks and comparison content are not included in those requests.
