FAQ
How does CSV to JSON conversion work?
The first row is treated as column headers. Each subsequent row becomes a JSON object where keys are the header names and values are the cell contents.
What delimiters are supported?
Comma (,), semicolon (;), tab, and pipe (|). The tool auto-detects the delimiter or you can choose one manually.
Does it handle quoted fields?
Yes. Fields wrapped in double quotes can contain commas, newlines, and escaped quotes (""). This follows the RFC 4180 CSV standard.
Can I convert JSON back to CSV?
Yes! Switch to the JSON → CSV tab, paste a JSON array of objects, and get a properly formatted CSV with headers derived from object keys.
