How is nested data shown?

Object keys are joined with dots to form column names; arrays are stored as their compact JSON text.

What if the root is an object, not an array?

The longest array under the root is used, and a note tells you which field was chosen.

Are large numbers preserved?

Yes. Numbers are read as text, so values like 12345678901234567890 keep all their digits.

How many records can I convert?

Guests up to 500 records; signed-in users up to 50,000.

JSON to Markdown table

Drop a JSON file and this page flattens it into a table, then formats that table as Markdown. Keys nested inside an object become dotted column names like address.city, while arrays are kept as compact JSON text so no value is dropped.

Because the conversion is client-side, it is safe for API responses or exports that contain user data.
