What JSON format does this tool accept?

The input must be a JSON array of objects, e.g. [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Plain objects, arrays of primitives, or deeply nested structures are not supported as table rows.

What happens with nested objects or arrays inside a row?

Nested values are serialized as a compact JSON string inside the table cell so no data is lost, while the outer structure remains tabular.

Is my data sent to any server?

No. All processing happens in your browser using JavaScript. Nothing is uploaded or stored externally.

Can I customize the table style?

The downloaded HTML includes inline styles that produce a clean, readable table. You can paste the markup into your project and apply your own CSS classes.

What if my JSON array has inconsistent keys across rows?

The tool collects all unique keys from every row and uses them as columns. Missing values appear as empty cells.
