CSV Column Extractor

Summary

Paste CSV data, pick the columns you want by name or number, and download or copy the extracted result.

How it works

1. Paste your CSV data into the input area.
2. The tool detects the delimiter and parses the headers automatically.
3. Check the columns you want to keep from the detected list, or type column numbers manually.
4. Toggle the "Include header row" option as needed.
5. Click Extract to generate the output, then Copy or Download the result.

Use cases

• Strip a large CSV export down to only the fields your script needs.
• Remove personally identifiable columns before sharing a dataset.
• Reorder columns by selecting them in the desired sequence.
• Prepare CSVs for import into tools that expect a specific column set.
• Quickly preview selected columns without opening a spreadsheet app.
• Extract a single column to get a plain list of values.
