FAQs
How are nested JSON objects handled in CSV?
Nested objects are flattened using dot notation for column headers. For example, {"address": {"city": "NYC"}} becomes a column named "address.city" with value "NYC".
Can I convert CSV with custom delimiters?
The tool primarily supports comma-separated values. For tab-separated or semicolon-separated data, you may need to replace the delimiter before conversion.
Does it handle large datasets?
The tool processes data in your browser, so it can handle moderately large datasets. For very large files, consider using a command-line tool or programming library.
Are special characters in CSV handled correctly?
Yes, the converter properly handles quoted fields, commas within values, and newlines within CSV cells according to the RFC 4180 standard.
