Frequently Asked Questions

What JSON structures are supported?

The tool handles JSON arrays (converted to tables) and JSON objects (converted to key-value lists). Nested objects can be flattened with the 'Flatten nested objects' option.

How does the flatten option work?

When enabled, nested objects are expanded using dot notation (e.g., 'address.city'). This creates a flat table structure suitable for documentation.

Can I convert API responses to Markdown?

Yes. Copy the JSON response from your API client or browser DevTools, paste it into the tool, and get a clean Markdown table or list.

What if my JSON has nested arrays?

Nested arrays are converted to JSON strings within the table cells. For complex nested structures, consider flattening first or using a more specialized tool.

Is my data private?

Yes. All conversion happens entirely in your browser. No data is uploaded to any server. You can even disconnect your internet and the tool still works.

Can I convert Markdown back to JSON?

This tool focuses on JSON-to-Markdown conversion. For Markdown-to-JSON, you would need to parse the table structure manually or use a specialized parser.

What Markdown format is generated?

The tool generates GitHub-Flavored Markdown (GFM) table syntax for arrays and bold-key lists for objects. Both formats are widely supported by Markdown renderers.

Does this handle large JSON files?

The tool handles JSON up to several megabytes. For very large files, the conversion may take a moment. All processing happens in your browser, so there are no server-side limits.

How do I convert a JSON API response to documentation?

Copy the JSON from your API client or browser DevTools (Network tab), paste it into the input area, and the tool generates a clean Markdown table you can embed in READMEs or docs.

What if my JSON is a single value (string, number, boolean)?

Single values are rendered as bold text: **value**. This is useful for documenting individual configuration values or API responses that return a single result.
