Every Nth Line Extractor

Summary

How it works

4. Click Extract to see the filtered lines on the right.
5. Copy the result with the Copy button.

Use cases

• Extract every other line from a doubled-spaced transcript.
• Pick lines at a fixed interval from log files for statistical sampling.
• Reduce a word list to a manageable subset by stepping through it.
• Split interleaved text blocks — e.g. extract only odd or even lines.
