CSV Column Extractor

Paste your CSV data and the tool automatically detects column headers. Use the checkboxes to select which columns to keep, then copy the filtered output. The tool preserves the original data format and handles quoted fields correctly.

The tool supports comma, tab, and semicolon delimiters. Select the appropriate delimiter to match your data format. Comma is the default for standard CSV files, tab for TSV files, and semicolon for European-style CSV files.

Yes. Fields enclosed in double quotes are parsed correctly even if they contain the delimiter character. For example, a field like "New York, NY" will be treated as a single value when comma is the delimiter.

Yes! All processing happens entirely in your browser. Your CSV data is never sent to any server. No data is collected, stored, or transmitted.

The tool works well with moderately sized datasets pasted directly into the text area. For very large files with thousands of rows, performance depends on your browser. All processing is done locally in your browser memory.
