Table to another format

Choose a table and a new format.

What the tool does

Reads a table from Excel (.xlsx), CSV or JSON and saves it in another of these formats. CSV gets a marker so Excel shows non-Latin text correctly.

How to use it

  1. Choose a file.
  2. Choose what to turn it into.
  3. Download the result.

Good to know

  • The first sheet of an Excel file is taken.
  • JSON must be a list of records or a list of rows.
  • Excel formulas are replaced by their values, styling is not carried over.
  • The CSV separator (comma, semicolon, tab) is detected on its own.
