About the CSV to reversed CSV format

Useful for chronological exports that need newest-first without a sort key.

Common use cases

  • Flipping time series
  • Reversing ranked lists

How to use this tool

  1. Paste or upload CSV (and a second file when the tool needs it).
  2. Set options if shown, then click Transform.
  3. Copy or download the result.

Tips for best results

  • Prefer Sort when you need order by a real column value.
  • Preview before download and keep a copy of the original file.

Common pitfalls

Quoted commas and newlines must stay valid CSV — paste intact exports when possible.
