CSV to JSON FAQ

What happens to the header row when converting CSV to JSON?

With "First row is header" checked (the default), the first row's values become the JSON object keys and each following row becomes one JSON object. If you uncheck it, every row — including the first — is converted into a plain JSON array of values instead.

Which delimiters are supported?

Comma, semicolon, tab, and pipe. Choose the one that matches your CSV file from the delimiter dropdown before converting.

Is my CSV uploaded anywhere?

No. Conversion runs entirely in your browser using JavaScript. Nothing is sent to TripleW Tools or any other server.
