FAQ
How are nested JSON objects handled when converting to CSV?▼
Nested objects are flattened using dot notation (e.g., user.name). Arrays inside objects are serialized to JSON strings to preserve their structure.
Can it handle CSVs with commas inside quoted fields?▼
Yes. The parser correctly handles quoted fields, escaped quotes, and multi-line values inside quotes.
What delimiters are supported?▼
Comma, semicolon, tab, and pipe — plus auto-detection based on your input.
