Frequently Asked Questions

How does JSON to Markdown conversion handle nested objects?

Nested JSON objects are converted to hierarchical Markdown with appropriate heading levels and indented lists. Deep nesting is represented using subheadings and nested bullet points for readability.

Are my files uploaded to a server?

This conversion runs on our server, so your file is uploaded over an encrypted connection. Files up to 15MB are deleted as soon as the converted file is sent back; larger files run as a background job and are deleted automatically about a day later. We don't share your files.

How are JSON arrays converted to Markdown?

JSON arrays are converted to Markdown bullet lists. If the array contains objects with consistent properties, they become Markdown tables with column headers. Simple value arrays become bulleted lists.

Does the converter preserve data types?

Yes. Numbers, booleans, and null values are displayed appropriately in the Markdown output. Strings are formatted as text, and code-like values are wrapped in backticks for proper rendering.

Can I convert large JSON files to Markdown?

Free conversions accept files up to 25MB. A one-time $2.99 Day Pass raises the limit to 100MB and unlocks unlimited conversions for 24 hours.

Is the Markdown output compatible with GitHub?

Yes. The converter produces standard GitHub Flavored Markdown (GFM) with proper table syntax, code blocks, and formatting that renders perfectly in GitHub README files and wikis.

How does the converter handle special characters in JSON strings?

Special characters are properly escaped for Markdown display. URLs become clickable links, and characters that have special meaning in Markdown are escaped to display correctly.

Can I customize the Markdown formatting?

The converter produces clean, standard Markdown that follows common conventions. For custom formatting, you can edit the resulting .md file in any text editor or Markdown editor.

Does the conversion work with JSON APIs and responses?

Yes. The converter handles any valid JSON, including API responses, configuration files, and data exports. Complex JSON structures are converted to well-organized Markdown documentation.

Is this free to use?

Your first conversion each day is free, with no signup and no watermark, for files up to 25MB. For more conversions the same day or files up to 100MB, a one-time $2.99 Day Pass unlocks unlimited conversions for 24 hours. No account or subscription is needed.
