Frequently asked questions
Which delimiter should I use?
Comma works almost everywhere. Use semicolon if your Excel expects it (common in European and some Vietnamese settings).
Does it keep all columns?
Yes. Columns are the union of keys across every object, so missing values become empty cells.
Is it free?
Yes, free with no limits.
