In short: Compare formulas, formatting, and workbook structure locally on macOS without uploading files or installing Microsoft Excel.
Why a text or table diff is not enough
An XLSX workbook is a package of worksheets, formulas, styles, names, comments, protection, VBA, and connections. A generic Mac diff tool can compare text or cells but may not preserve those workbook meanings.
Compare locally on macOS
xlLens reads supported workbook files directly on the Mac. Workbook contents are not uploaded, and Microsoft Excel does not need to be installed or automated.
- Select the previous and current files
- Choose Basic, Smart, or Table mode
- Filter the result and export an audit report
Handle inserted rows and columns
Smart mode realigns content after insertions and deletions while retaining the original address from each workbook. Use Basic mode instead when movement itself must be reported as a change.
Know the visual boundary
xlLens compares workbook semantics and detects package-level object changes, but it does not compare rendered chart, shape, pivot, or image pixels. Pair it with a visual tool when pixel rendering is the primary requirement.
