About CSV to Excel

CSV is a plain list of values with no formatting and no types. Converting it back to XLSX gives you a real workbook with proper columns, ready for filtering, formulas and charts.

How to use it

  1. Upload your CSV file.
  2. Convert it to XLSX.
  3. Download the workbook.

Worth knowing

CSV carries no information about what a column means, so long numbers such as IDs, phone numbers and postcodes can be read as figures and lose their leading zeros. Check those columns first.

Common questions

My delimiters look wrong — why?
CSV files vary: some use semicolons, some commas, depending on regional settings in whatever produced them.
Is anything lost?
Nothing is lost from the CSV; formatting is gained, since a CSV never had any.
