CSV Column Extractor
Pick specific columns from a CSV file and download the result — great for cleaning large datasets
Drop a CSV file or click to upload
How it works
- • Upload or paste a CSV — all columns are detected from the header row.
- • Check the columns you want to keep — all other columns are discarded.
- • Download the extracted CSV. Column order matches your selection order (left to right).
- • All processing happens locally in your browser.
