How the CSV sorter works
- Paste CSV data with a header row - a sample loads automatically.
- Choose which column to sort by, ascending or descending, and whether to sort numerically.
- Copy the sorted CSV output.
FAQ
Can I sort by any column?
Yes - the column dropdown automatically populates from your CSV's header row, so you can pick any column to sort by.
How do I sort numbers correctly?
Check "Treat column as numbers" - otherwise values are sorted alphabetically, which puts "10" before "9".
Does this handle commas inside quoted values?
This tool uses simple comma splitting for speed and clarity - for CSV with quoted fields containing commas, remove the quotes or use a spreadsheet app instead.
Is the header row included in sorting?
No - the first row is always treated as a header and stays fixed at the top of the output.
