FAQ

What JSON format is supported?

The converter accepts a JSON array of objects (e.g., [{...}, {...}]). Each object becomes a row. Nested objects are flattened using dot notation (e.g., "address.city").

How are nested JSON objects handled?

Nested objects are automatically flattened with dot notation. For example, {"user": {"name": "John"}} becomes a column "user.name" with value "John".

Is there a file size limit?

Processing happens entirely in your browser, so there is no server-side limit. However, very large files (over 50MB) may slow down your browser.
