CSV Column Reorder
Reorder and remove columns in CSV files
Change the column order in a CSV without opening a spreadsheet. Move columns up or down into the order you need, drop the ones you do not want, preview the result, and download the rearranged file.
Column order matters more than it should. Import templates frequently require an exact sequence, and reordering by hand in a spreadsheet means cutting and inserting columns one at a time — slow, and easy to get subtly wrong on a wide file.
Removing columns is often the more valuable half. Trimming an export down to the fields a destination actually accepts avoids import errors and means you are not handing over personal data that the recipient never asked for.

Frequently Asked Questions
How do I reorder the columns?
Use the up and down controls next to each column to move it through the order. The preview updates as you go so you can confirm the arrangement before downloading.
Can I remove columns as well as reorder them?
Yes. Removing unneeded columns is often the point — it keeps an import within the fields a destination accepts and avoids sharing data the recipient does not need.
Does the data stay with the right header?
Yes. Moving a column moves its values with it, so headers and data never drift apart.
Why does column order matter for imports?
Many import templates and bulk-upload tools map by position rather than by header name, so a file with the right columns in the wrong order fails or, worse, loads values into the wrong fields.
Can I rename the columns here?
No — this tool changes order and selection. Use the CSV header editor to rename headers.
Is my file uploaded?
No. Reordering happens in your browser and the contents are not sent to the app server.
