A comparison you can explain.
ExactDiff separates file reading, matching rules, normalization, and evidence so every result can be reproduced.
- 01
Select files locally
The browser grants access only to files you explicitly choose. ExactDiff reads their contents in the current tab and does not transmit them to an application server.
- 02
Match the right records
Spreadsheet tools use a stable key instead of row position. This prevents reordered exports from appearing as thousands of false changes.
- 03
Apply explicit rules
Trimming, case handling, and numeric tolerance are visible settings. ExactDiff never silently decides that two different values are equivalent.
- 04
Review and export exceptions
Filter added, removed, changed, and duplicate records. Download a CSV report and retain SHA-256 hashes of the selected source files.
What ExactDiff does not do
It does not upload files, execute source code, recalculate Excel formulas, or claim that a structural audit proves business logic. Scanned PDFs require OCR, which is not included in the initial release.
