Repair CSV file
Repair a CSV file in the browser
Upload a messy export, apply one-click repairs, preview the result, and download a cleaner import-ready CSV.
What this problem usually means
A useful CSV repair workflow should not require writing one-off scripts or cleaning a file manually in a spreadsheet. The fastest path is usually: upload the export, scan for structural issues, apply safe fixes, review the preview, and export a cleaner CSV for the next import attempt.
Why it happens
- CSV files often break after being exported from one system and imported into another with different expectations.
- Spreadsheet tools can silently change delimiters, line endings, or how empty rows are handled.
- A file that looks readable to a person can still be structurally wrong for an importer.
What ImportFix checks
- Header quality, duplicate headers, and empty columns
- Row shape, blank rows, and duplicate rows
- Delimiter detection, line endings, and malformed quote warnings
- Previewable before-and-after repair output
Common repairs
Remove blank rows and trim unnecessary whitespace
Normalize delimiters and line endings
Rename duplicate headers and standardize row lengths
Export the repaired file as cleaned CSV
When to review manually
Repairing the file structure does not replace checking the data itself. If a row looks ambiguous, use the repaired preview and verify a few records in the destination system before importing into production.
