UlvixorCSV Cleaner & Duplicate Remover
Clean up your CSV in seconds: trim stray whitespace from every cell and remove rows that are exact duplicates. It's an all-in-one CSV cleaner and duplicate remover that runs 100% locally in your browser.
How it works
- Paste your CSV into the input panel (or use the built-in example).
- The tool trims leading and trailing whitespace from every cell.
- It then finds and removes rows that are identical to one already seen.
- A summary shows the number of rows processed, duplicates removed, and cells trimmed.
- Copy the cleaned CSV or download it as a .csv file.
Use cases

- Clean up stray spaces introduced when copying data from Excel or a form.
- Prepare a CSV for import into a database that rejects duplicate records.
- Standardize CSV files from different sources before merging them.
