Still comparing workbooks by eye?
Workbook version reviews should not feel this fragile
Files multiply into final, final-v2 and final-revised, but the reason behind each change stays hidden. One missed cell can change a close, forecast, or client report.
One inserted row makes everything look different
Smart realigns inserted or removed rows and columns so you review the real change while keeping original row numbers.
You need evidence of exactly what changed
Review values, formatting, structure, names, VBA, connections, and protection in one result, then save a report.
Inside xlLens
Make complex workbook changes easy to scan
Values, formulas, formatting, structure, VBA, and connections use distinct colors and dedicated views. See both the changed location and its cause in one workspace.
Comparison depth
Matching values do not always mean matching workbooks
Hover or focus a card to see how each capability appears in the working app.

From two files to a defensible report
- 1
Choose two files
The native file picker grants access only to the workbooks you select.
- 2
Choose the comparison mode
Use Smart for most workbooks, Basic for strict address matching, or Table for key-based records.
- 3
Inspect only the differences
Filter by change type, search the worker-backed index, and jump between original rows.
- 4
Export the evidence
Create an XLSX or CSV report containing audit hashes, alignment evidence, and app version.
Measured performance
The conditions travel with the number
Measured with generated style-heavy XLSX files. Results vary with formulas, formatting and sheet structure; this is not a competitor speed test.

View purchase detailsQuestions
Before you compare
Does xlLens upload my workbooks?
No. Parsing, comparison, search, paging, and report generation run locally on your computer.
Do I need Microsoft Excel?
No. xlLens reads supported spreadsheet formats directly and does not automate an installed copy of Excel.
What is the difference between the trial and xlLens?
The trial evaluates the same features for a limited period. Purchasing removes the time limit for the licensed major release.
Is the license a subscription?
No. The license does not expire. It covers the purchased major release and its minor updates; future major upgrades are optional.
