Frequently Asked Questions
What delimiters are supported?▾
The tool supports comma (,), semicolon (;), tab, and pipe (|) delimiters. By default, it auto-detects the delimiter from the first line.
Does the first row become JSON keys?▾

How are quoted fields handled?▾
Fields enclosed in double quotes are handled correctly, including fields that contain the delimiter character or newlines.
Is my data secure?▾
Yes, all processing runs in your browser. No CSV data is sent to any server.
