Frequently Asked Questions

How does the tool handle missing keys in some array objects?

The engine collects the union of all properties across all objects. When an item lacks a property, its corresponding table cell is left cleanly blank.

Can I convert a single configuration object instead of an array?

Yes. When you provide a single key-value object, the tool automatically constructs a 2-column table with 'Key' and 'Value' headers.

Does converting JSON tables transmit my data to a server?

No. All parsing and Markdown generation execute 100% locally in your web browser memory using client-side JavaScript.
