Frequently Asked Questions(click to expand)

How do I convert CSV to JSON?

Paste your CSV data in the left pane. The tool auto-detects the delimiter (comma, tab, pipe, semicolon) and converts each row to a JSON object using the header row as keys.

What if my CSV has no header row?

Uncheck the "Header Row" option. Columns will be named column_1, column_2, etc.

Can I convert JSON back to CSV?

Yes! Click "Swap Direction" to switch to JSON → CSV mode. Paste a JSON array of objects and get properly formatted CSV output.
