Reconcile two files

Start with the files. WorkTools asks only for settings it actually needs.

🔒 Spreadsheet contents stay in this browser. WorkTools has no upload endpoint and stores no file data.
PRIVATE BY DESIGN

Your file stays between you and your browser.

WorkTools serves the interface. The file contents are read and processed locally in browser memory, then you decide what to export.

HOW IT WORKS

Reconcile spreadsheet exports without VLOOKUP or SQL

1. Choose two files

Load Excel, CSV, TSV or TXT data. For workbooks, select the worksheet and header row you want to use.

2. Pick the identifier

Match records by SKU, material number, part number, order ID or another column that identifies one record.

3. Export the exceptions

Review changed values, rows that exist only in one file and duplicate identifiers, then export the result.

Common uses

  • Compare system inventory with a physical count.
  • Compare old and new supplier price lists.
  • Find missing SKUs between two exports.
  • Check whether quantities or prices changed between file versions.
  • Find duplicate IDs before importing data into another system.

Your files stay on your device

The tool performs parsing, matching and export generation in the browser. The web server serves the application files, but the selected spreadsheet contents are not uploaded to WorkTools.
