FAQ
How does the converter handle nested JSON objects?
Nested objects are automatically flattened using dot notation. For example, {"user": {"name": "John"}} becomes a column called "user.name" with the value "John".
What happens with JSON arrays inside objects?
Arrays are handled intelligently — simple arrays are joined into a single cell value, while arrays of objects are expanded into separate rows or flattened depending on the structure.
Does it work with JSON from REST APIs?
Yes. You can paste JSON response data directly from any REST API. The tool handles the common API response patterns including data wrapped in a top-level object like {"data": [...]}.
Can I choose a different delimiter instead of commas?
Yes. The converter supports comma, semicolon, and tab delimiters. This is useful when your data contains commas or when you need TSV output for certain applications.
What's the maximum JSON size I can convert?
The tool supports files up to 10MB. Since all processing happens in your browser, performance depends on your device. Most JSON files under 10MB convert in under a second.
