Column Extractor

Pull, reorder or swap columns from CSV, TSV, logs or any delimited text.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Column Extractor works

Each line is split on the delimiter (detected for you, and quoted values stay together), then the columns you pick are joined with the output separator. It works like the Unix cut command, without a terminal.

Input: CSV, TSV, TXT, LOG. Output: CSV, TSV, Text.

How to use Column Extractor

Paste or open your text.
Click column numbers or type a list like 3,1.
Pick the output separator.
Copy or download.

Tips

Text never leaves your device, so it is safe for drafts and private notes.
