Frequently Asked Questions
How are headers handled in CSV to JSON?
If 'First row is header' is enabled, the first row becomes JSON object keys. Otherwise, arrays are generated with numbered indices.
What delimiters are supported?
Common delimiters include comma (,), semicolon (;), tab, and pipe (|). You can specify any custom delimiter.
How are quoted values handled?
Values enclosed in quotes are parsed correctly, including commas within quoted strings. Standard CSV quoting rules apply.
What JSON structure is expected for JSON to CSV?
The tool expects an array of objects with consistent keys. Each object becomes a row, and keys become column headers.
Is there a file size limit?
Processing happens in your browser, so very large files may be slow. For best performance, keep files under 10MB.
