Question 1

What JSON structures are supported?

Accepted Answer

The tool supports JSON arrays of objects (the most common API response format), a single JSON object (which is treated as one data row), and arrays of primitives (displayed as a single-column Value table). Nested objects are stringified in cells.

Question 2

How are column headers determined?

Accepted Answer

Column headers are derived from all unique keys found across every object in the array — not just the first object. This ensures that if some objects have extra keys, those columns still appear in the output table.

Question 3

What happens with null or undefined values?

Accepted Answer

Null and undefined values are displayed as empty strings in the Markdown table. Other falsy values such as 0 or false are shown as-is, so no data is silently dropped during conversion.

Question 4

Can I convert a single JSON object?

Accepted Answer

Yes. If you paste a single JSON object (not wrapped in an array), the tool automatically wraps it in an array and produces a one-row Markdown table with all keys as column headers. This makes it easy to inspect any JSON object as a table.

Question 5

How do I get the Markdown table into my project?

Accepted Answer

Click Copy to copy the table to your clipboard or click Download to save it as a .md file. The table can be pasted directly into GitHub READMEs, documentation sites, Notion, Obsidian, or any other Markdown-aware editor.
