FAQ
Can I extract columns by name instead of index?
Yes. This tool uses the header row so you can pull a column by its label.
What if the column does not exist?
The tool will tell you the column was not found so you can check the header row first.
How it works
Paste CSV content, choose a header name, and pull out a single column for faster cleanup, reuse, or export. The result is produced immediately so you can review it before copying or using it elsewhere.
Privacy
The tool is designed to process ordinary input in your browser. Avoid pasting passwords, private keys, access tokens, personal records, or other sensitive production data into any online utility.
Limitations
This utility handles the focused workflow described on this page. Check the result before production use, especially when an input depends on a vendor-specific format, security rule, or external standard.
