Clean it once. Re-run it every week.

Rote Workspace fixes the CSV and Excel files you get every week — spaces, blanks, duplicates, dates, columns — and saves the steps, so next week's file takes one click.

  • Files stay on your device
  • Every change previewed first
  • Steps saved as workflows

How it works, in seven steps

  1. Open a fileDrop a CSV or pick one. It is processed locally in your browser; its contents are not uploaded.
  2. Inspect the dataSee the rows, the columns and the problems found — nothing changes yet.
  3. Select an operationTrim spaces, remove empty rows, tidy headers, find duplicates…
  4. Preview the changesChanged cells are highlighted; switch to Before to see rows that would go.
  5. ApplyKeep the operations you want ticked; untick one to undo it.
  6. Download the resultA new CSV. Your original file is never touched.
  7. Save the workflowKeep the settings in this browser or as a JSON file for next time.

You can bring this back in Settings.

Built for the file you get every week

  • Repeat it in one clickEvery fix you make becomes a step. Save the steps as a workflow and run them on next week's file — the check tells you first if a column is missing or renamed.
  • Problems found for youEmpty rows and columns, stray spaces, repeated rows, messy headers, mixed capitals and dates that read two ways are listed the moment a file opens.
  • Nothing changes by surpriseEvery change is previewed cell by cell before you download. Values stay text — 00501 stays 00501 — and your original file is never written to.
  • Private by designFiles are read and processed on your device, in your browser. Their contents are not uploaded; no account, no sign-up.
