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.
