CSV Column Extractor
Extract specific columns from CSV files. Select which columns to keep and download a new CSV with only the data you need.
Why Use CSV Column Extractor?
When working with large CSV files, you often only need specific columns. Rather than manually deleting unwanted columns in a spreadsheet, use our Column Extractor to quickly select and export only the columns you need. Perfect for data cleaning, report generation, and preparing data for import.
Frequently Asked Questions
Can I change the column order?
Currently, columns are extracted in their original order. Select columns in any order, but they'll appear in the output following the original file's column sequence.
Is my data secure?
Yes! All processing happens locally in your browser. Your CSV file is never uploaded to any server.
Can I extract from multiple files at once?
This tool works with one file at a time. For multiple files, use the CSV Merger tool to combine them first, then extract columns.
What happens to empty columns?
Empty columns are preserved if you select them. The tool extracts exactly what you choose, including blank cells.
Can I rename columns?
Not directly in this tool. To rename columns, download the extracted CSV and edit the first row, or use a spreadsheet application.
