Frequently Asked Questions
Does it handle CSV with headers? ▼
Yes. When "Header row" is enabled, the first row becomes the key names in each JSON object. Without headers, rows are converted to arrays.
What delimiters are supported? ▼
Comma, semicolon, and tab delimiters are auto-detected. Most CSV files use commas, but European formats often use semicolons.
Is my data sent to a server? ▼
No. Conversion uses PapaParse in your browser. Your data never leaves your device.
