Why CSV Cleaning Matters
Every data analyst and developer has faced this: messy spreadsheets with duplicates, wrong date formats, encoding issues, and trailing spaces.
The Solution: CSV Cleaner
I built a free web tool that cleans CSV files in seconds:
- Remove duplicates
- Standardize dates
- Fix encoding
- Trim whitespace
- And 5 more operations
Try it: http://23.27.134.52:3000
How It Works
- Drag-drop your CSV file
- Select cleaning operations
- Download the clean file
All processing happens in your browser — no data leaves your computer.
