JSON and YAML tips

  • Use spaces, not tabs, for YAML indentation.
  • Quote YAML values when their type or special characters could be ambiguous.
  • JSON requires double-quoted keys and string values.

JSON and YAML Converter FAQ

What is the difference between JSON and YAML?

Both formats represent structured data. JSON uses braces, brackets, and quoted keys, while YAML uses indentation and is often easier for people to edit by hand.

Can I convert YAML back to JSON?

Yes. Use the YAML → JSON tab to validate YAML and generate formatted JSON.

Will conversion preserve my data?

The converter preserves the data structure and values that both formats support. Output formatting and comments are not preserved when converting.

Why is my JSON or YAML invalid?

JSON commonly fails because of trailing commas or unquoted keys. YAML errors often come from inconsistent indentation, missing colons, or tabs used for indentation.

Is my data private?

Yes. Conversion and validation run locally in your browser. DevKit does not upload or store the content or files you use.
