WWorkTools
CSV UTILITY

Split a large CSV into manageable parts.

Choose how many rows each output file should contain. Headers are preserved in every downloaded part.

✓ No upload✓ No account✓ Local processing✓ Export results

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

  • Split imports that exceed another system’s row limit.
  • Break a large export into manageable chunks.
  • Create equal-sized CSV batches.

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.
