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.

Fast

The tool focuses on one clear work task instead of forcing you into a larger software platform.

Private

Selected file contents are processed in browser memory and are not uploaded to WorkTools.

Predictable

Ambiguous or invalid data is surfaced for review instead of being silently guessed.

Common uses

  • Find duplicate SKUs before an import.
  • Check duplicate order or material numbers.
  • Locate repeated IDs in a master-data export.

Your files stay on your device

WorkTools serves the application code from the web server, while spreadsheet parsing and calculations run in your browser. There is no file-upload endpoint for these tools.
