What JSON formats are supported?

The converter accepts a JSON array of objects (the most common format from APIs). It also accepts a single JSON object, which is wrapped in an array automatically.

How are nested objects handled?

Nested objects are flattened using dot notation. For example, { address: { city: 'London' } } becomes a column named 'address.city'.

How are arrays inside JSON handled?

Arrays inside JSON values are serialized as JSON strings in the CSV cell. Deep nesting is kept as-is for readability.

What delimiters are supported?

Comma (,), semicolon (;), tab, and pipe (|) are supported. Use semicolons if your data contains commas.

Can I download the CSV directly?

Yes. Click the Download button to save the output as a .csv file.

Is my JSON data uploaded anywhere?

No. All conversion happens in your browser using JavaScript. Your data never leaves your device.
