Repair a CSV file online

Repairing a CSV file usually means restoring a consistent row structure so import tools stop failing. CSVDoctor detects broken lines, auto-fixes common issues where safe, and gives you a corrected CSV download without using any backend.

What gets repaired

The repair flow focuses on structural problems rather than content changes. That includes row length mismatches, broken or unclosed quotes, trailing delimiters, malformed escape characters, and blank rows that should not be part of the final file.

Examples of CSV errors

id,name,comment
1,Alice,"ready"
2,Bob,"missing close
3,Carla,done,extra

The second bad row needs a closing quote. The third row has an extra comma that creates a fourth field even though the file only expects three columns.

Why repair in the browser

CSVDoctor is a static site, so it can be deployed directly to Cloudflare Pages while keeping every uploaded file local. That is useful for finance exports, user lists, internal data dumps, or any CSV you do not want to send to a third party.

Repair workflow

  • Upload the CSV file or drag and drop it into the page.
  • Choose the delimiter if auto-detection needs a manual override.
  • Review line-level issues and the first 50 rows in the preview table.
  • Download the corrected CSV once the structure looks right.
