    • Alternatively, use the Import button to load JSON from a local file or URL.

  2. Step 2 – Configure conversion options

    • Use the gear icon settings to customize the output.
    • Toggle "Sort keys alphabetically" to organize your data consistently.
    • Enable "Include comments" to add a timestamp header to your YAML file.

  3. Step 3 – View and Verify YAML

    • The converted YAML appears instantly in the right panel.
    • The converter automatically handles indentation and special character escaping.
    • Check the output to ensure the structure matches your expectations.

  4. Step 4 – Export your YAML file

    • Click the Copy button to copy the YAML code to your clipboard.
    • Use the Download button to save the result as a .yaml file.
    • Use this YAML for Kubernetes configs, Docker Compose, or application settings.

Frequently Asked Questions

How does JSON to YAML conversion handle data types?

JSON data types are converted to their YAML equivalents: strings, numbers, booleans, arrays (sequences), and objects (mappings) are all preserved. YAML's more flexible syntax allows for cleaner representation of these types.

What's the difference between including comments and not?

When 'Include comments' is enabled, the converter adds a header comment with generation timestamp. Comments help document the YAML file's origin but aren't part of the actual data structure.

Why would I want to sort keys alphabetically?

Sorting keys alphabetically makes the YAML output more predictable and easier to compare between different versions. This is useful for version control and when you need consistent output formatting.

How are nested JSON objects represented in YAML?

Nested JSON objects become nested YAML mappings with proper indentation. YAML uses indentation (typically 2 spaces) to show the hierarchical structure, making it more readable than JSON for complex data.

Is my data secure?

Yes, all data processing happens entirely in your browser. Your JSON data is never sent to any server, ensuring complete privacy and security.
