Convert CSV to JSON, Excel, and XML

CSV is everywhere, but you often need it in another shape: JSON for an API, XLSX for a colleague, or XML for an import. This converter transforms CSV and Excel files between formats in your browser, so you can reshape data quickly without writing a script or pasting it into an online box you do not trust.

Common fixes

  • Garbled characters? Save the source as UTF-8
