What is Line Tools?

Line Tools batches the small text chores that come up daily — sorting, deduping, prepending line numbers — so you can stop dropping into a terminal for awk one-liners.

How to use

  1. Paste your text.
  2. Pick the operations you want.
  3. Copy the cleaned-up output.

Frequently asked questions

Is sorting locale-aware?

It uses the browser default locale via Intl.Collator.
