CSV Swap Columns

You specify two column positions (using 1-based indexing), and the tool swaps all values between those columns across every row in your CSV data.

If a row doesn't have the specified column, that row remains unchanged. The tool only swaps columns that exist in each row.

Yes, completely safe. All processing happens locally in your browser. Your data is never uploaded to any server.

No, this tool swaps exactly two columns at a time. For multiple swaps, you can run the tool multiple times or use a more advanced CSV editor.

Yes, you can specify any delimiter (comma, semicolon, tab, pipe, etc.) to match your CSV format.

CSV (Comma-Separated Values) is a plain text format for storing tabular data. Each line represents a row, and values are separated by delimiters (usually commas).

Yes, you can swap any two columns regardless of whether they are adjacent or far apart in the CSV structure.

Yes, if your header is in the first row and you include it in the swap, it will be swapped along with the data. You can exclude the header by starting your data from row 2.

The tool uses simple delimiter-based splitting. For complex CSV with quoted fields containing delimiters, you may need to preprocess your data or use a more sophisticated CSV parser.

Yes, once the page loads, all operations happen locally in your browser. You don't need an internet connection after the initial load.

The tool can handle large CSV files, but performance depends on your browser's memory. For very large files (100MB+), consider splitting them first.

Yes, just change the delimiter setting to match your file format (tab for TSV, semicolon for European CSV, etc.).
