Line Range Extractor

Summary

Paste any text, enter line ranges like "1-5, 10-15", and instantly extract those lines with a numbered gutter.

How it works

1. Paste or type your text into the input panel on the left.
2. Enter one or more line ranges in the range field (e.g. "1-3, 7-10").
3. Click Extract Lines or press Enter — matching lines appear in the output panel with their original line numbers.
4. Click Copy Output to copy the extracted lines to your clipboard.
5. Use the Clear button to reset both panels and start over.
