Column extractor

Keep or drop columns from CSV/TSV text — pick them like '1,3-5' — and re-emit cleanly.

Text is parsed in this browser — nothing is sent anywhere.

Up to 300,000 characters and 50,000 rows. Quoted fields containing the delimiter are preserved.

How to use

  1. Paste delimited text.
  2. Enter the column selector and mode.
  3. Copy or download the result.

What it supports

Real CSV parsing — quoted fields containing the delimiter are preserved. Columns are 1-based; 'keep' selects, 'drop' removes. Up to 300,000 characters / 50,000 rows.
