Tips

  • CSV opens as one column in Excel? Your Excel uses ; as a list separator (common in Europe). Choose CSV (semicolon).
  • Accented characters look wrong? Our CSVs include a UTF-8 BOM so Excel reads them correctly.
  • JSON input should be an array of objects, e.g. [{"name":"Ana","age":31}].
