Limitations and notes

  • Values are exported, not formulas, formats, colours or charts.
  • Text starting with = + - @ is neutralised so Excel does not run it as a formula.

Frequently asked questions

Why is there a BOM?

So Excel shows accents correctly when opening the CSV. Turn it off if your program does not need it.
