How to use it
The first CSV row is used as column headers. On the JSON side, an array of objects is expected ([{"name":"Ada"}, ...]). Commas and delimiters inside quotes are handled correctly.
Frequently Asked Questions
What happens if a value contains a comma?
Wrap the value in double quotes ("Paris, France") — the tool supports RFC 4180-style quoting.
Can I use a different delimiter (semicolon, tab)?
Yes, pick one from the dropdown above — European-format Excel CSVs typically use a semicolon.
