  2. Set options if shown, then click Transform.
  3. Copy or download the result.

Tips for best results

  • Prefer Remove for a short deny-list; use Extract for a short allow-list.
  • 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.
