Frequently Asked Questions
What JSON structure does this accept? ▼
The converter expects a JSON array of objects: [{"key": "value"}, ...]. Each object becomes a row, and each unique key across all objects becomes a column header. Single objects are also supported.
How are nested objects handled? ▼
Nested objects are serialized as a JSON string within the CSV cell. For example, a nested object like {"address": {"city": "Lagos"}} will appear as the string {"city":"Lagos"} in the CSV.
Are special characters escaped? ▼
Yes. Values containing commas, double quotes, or newlines are automatically wrapped in double quotes and internal quotes are escaped as double double-quotes, following the RFC 4180 CSV standard.
