Use this tool to fix column order in exported data, align structure for import templates, or simply reorganize fields for better readability. It’s ideal for modifying CSVs without needing spreadsheet software.

Useful Tools & Suggestions:

Once you’ve rearranged your CSV columns, CSV Column Exporter can help you pull out just the updated order for sharing or further use. And if you need to clean up extra fields after the swap, CSV Column Deleter makes it easy to slim things down without touching the structure you just set.
