CSV Column Reorder and Rename

Open or paste a CSV with a header row, move the columns where you need them, rename them, drop the ones you do not want, and take the result. The file never leaves your browser.

Result

2 rows × 4 columns

Comma-separated
Name,Qty,Price,Notes
Widget,4,2.50,"blue, small"
Gadget,10,1.20,

How it works

  1. Paste the CSV or open a file; the separator (comma, semicolon or tab) is detected.
  2. Use the arrows to move a column, the box to rename it, the checkbox to drop it.
  3. Check the preview of the first rows.
  4. Copy the new CSV or download it.

What people use it for

  • Preparing an import

    Put your columns in the order a form, a CRM or a mailing tool expects.

  • Cleaning an export

    Remove the internal ID and notes columns before sharing a file.

  • Fixing headers

    Rename “Qty” to “Quantity” without opening a spreadsheet.

Questions

Is my file uploaded?
No. The file is read and rewritten in your browser tab. Nothing is sent, stored or put in a link.
Are cells changed?
No. Values are copied as they are, only the order, the names and the kept columns change. Cells that contain the separator, a quote or a line break are put between quotes, as the CSV format (RFC 4180) requires. Quotes inside a cell are doubled.
What about formulas?
A cell beginning with =, +, - or @ stays exactly as it was. A spreadsheet may read it as a formula when you open the file, as it did in the original, so only open files you trust.
What are the limits?
300,000 characters, 50,000 rows and 200 columns. A row shorter than the header gets empty cells; a row longer than the header loses its extra cells, and a message tells you how many rows are concerned. The first row is always the header.
