Frequently Asked Questions

What delimiters does the CSV to JSON converter support?▼
Comma (standard CSV), semicolon (common in European CSVs), tab (TSV format), and pipe (|). The delimiter is auto-detected or can be manually selected.
Does it handle quoted fields containing commas?▼
Yes. Fields enclosed in double quotes, including those containing commas, line breaks, or special characters, are parsed correctly according to the RFC 4180 CSV standard.
What JSON structure is produced?▼
An array of objects, where the first CSV row becomes the object keys (headers) and each subsequent row becomes an object. For example: [{"name":"Alice","age":"30"},{"name":"Bob","age":"25"}].
Is the conversion done in the browser?▼
Yes. All parsing and conversion happens locally in your browser. Your CSV data is never uploaded to any server.
What if my CSV has no headers?▼
Toggle 'no headers' mode and the output will use column indices as keys (col0, col1, col2, etc.).
