Everything is processed inside this browser tab. Pixuna does not upload your text or files to a server.

How to use Date & Number Format Converter

  1. Paste CSV into the box, or choose Open a file to load a .csv, .tsv, or .txt file.
  2. Leave the delimiter on automatic detection, or pick it yourself, and set whether the first row is a header.
  3. Pick dates or numbers, the columns to convert, and the input and output formats.

What to know

You choose the input date order because values like 03/04/2024 are ambiguous. Impossible dates are left unchanged.

Cells that are not recognized are left as they were and counted, so you can review them.

File handling: This tool runs in your browser. Your text or file is processed in the tab on your device, and Pixuna's code does not upload it to a server. You can confirm this in your browser's network panel.
