CSV Column Extractor

A CSV column extractor helps you reduce a large dataset to only the fields you actually need. Instead of copying columns manually in a spreadsheet, you can paste your CSV data here, enter the column names or indexes you want to keep, and instantly get a smaller CSV output ready to copy, save, or use in another workflow.

How it works

This tool reads the header row and matches the columns you request. You can specify columns by name such as name,email or by numeric position such as 0,2. The result preserves CSV formatting while removing the unwanted fields, which makes it useful for quick preprocessing before importing data into another system.

Common use cases

  • Keep only contact fields before sending a list to a CRM
  • Reduce exported reports before sharing them with teammates
  • Remove unnecessary columns from analytics or survey data
  • Prepare a simplified CSV for scripts, dashboards, or spreadsheets

Why use an in-browser extractor

Everything runs directly in your browser, so your CSV content stays on your device. That makes this tool convenient for fast cleanup tasks and for datasets you would rather not upload to a third-party service.

If you regularly work with spreadsheets, exports, or tabular datasets, this CSV column extractor gives you a quick way to isolate the exact columns you need without changing the rest of your workflow.
