CSV is a flat format, so nested objects and arrays cannot be directly represented as columns. When this tool encounters nested values, it serializes them as JSON strings within the CSV cell and shows a warning. For complex nested structures, consider flattening your data first.

Everything you need to know about this tool.
No. All conversion happens entirely in your browser using client-side JavaScript. Your JSON data never leaves your device.
The tool accepts JSON arrays of objects (e.g. [{...}, {...}]). Single objects, primitives, and arrays of non-objects are not supported because they don't map naturally to CSV rows and columns.
If some objects in the array have properties that others lack, the missing values will appear as empty cells in the CSV output. All unique keys across all objects are used as column headers.
Nested objects and arrays are serialized as JSON strings within the CSV cells. The tool displays a warning to alert you about this behavior so you can decide whether to pre-flatten your data.
Booleans become 'true' or 'false', numbers become their string representation, and null values become empty strings in the CSV output.
