What is the CSV Column Extractor?
Large CSV files often contain dozens of columns you don’t actually need. Manually deleting these columns in Excel can be slow and annoying, especially for large datasets or files you want to quickly process.
Our CSV Column Extractor automatically parses your data and provides an interactive checklist of all your columns. Simply check the columns you want to keep, and the tool will instantly generate a new, lighter CSV file.
How to extract columns
- Paste your raw CSV data into the Original CSV panel.
- The tool will parse the header row (if “First row is Header” is checked) and list all the available columns as selectable tags.
- Click on the column names to select or deselect them.
- The Extracted CSV Output panel will automatically update to include only the columns you selected.
