Markdown to JSON Converter [2025]

Smart Data Type Detection

The converter intelligently detects and preserves data types in your Markdown table. Numbers remain numeric, boolean values (true/false) are properly typed, and empty or "null" cells are converted to JSON null values. The converter can even recognize and parse array and object literals within table cells.

Nested Property Support

Use dot notation in your table headers to create nested objects in the JSON output. For example, a header like user.address.city will create a nested structure:

{
  "user": {
    "address": {
      "city": "New York"
    }
  }
}

Formatting Controls

Customize your JSON output with options for pretty printing, indentation size, and array wrapping. Whether you need compact JSON for production or readable JSON for documentation, the converter has you covered.

How does type detection work?

The converter analyzes cell content to detect appropriate data types:

• Numbers (like "42" or "3.14") become numeric values
• "true" and "false" become boolean values
• Empty cells or "null" become null values
• JSON-formatted arrays or objects are parsed into their appropriate structures
• Everything else remains as strings

How do I create nested structures?

Use dot notation in your table headers to create nested JSON objects. For example, columns named "user.name", "user.email", and "user.details.age" will be converted into a nested structure with "user" as the parent object containing "name", "email", and a "details" object with an "age" property.

Is my data secure?

Yes, all conversion happens entirely in your browser. Your markdown data is never sent to any server, ensuring complete privacy and security of your information.

Can I use the output in my application?

Yes, the generated JSON is fully standards-compliant and ready to use in any application that accepts JSON data. You can copy it directly or download it as a file for immediate use in your projects.
