JSON ↔ YAML

Convert between JSON and YAML in either direction.

About JSON ↔ YAML

Translate structured data with a standards-focused YAML parser while keeping types and parse errors explicit.

The converter parses the source into structured values and then serializes the destination format. This makes syntax errors explicit and preserves normal strings, numbers, booleans, arrays, objects, and null values.

How to use it

  1. Enter or select your source data.
  2. Adjust the available options and run the tool.
  3. Review, copy, or download the result.

Common use cases

  • Translate deployment settings between JSON and YAML.
  • Create readable YAML from an API or package configuration.
  • Convert a YAML example into JSON for a tool that only accepts JSON.

Worked example

Convert a JSON deployment configuration into readable YAML.

Limitations and responsible use

  • YAML comments and original formatting are not preserved through conversion.
  • Advanced YAML constructs may be resolved into ordinary data structures.
  • Conversion checks syntax, not whether the configuration is valid for a particular product.

Frequently asked questions

Will YAML comments appear in the JSON?

No. Comments are not data values and are discarded during parsing.

Can JSON always be represented as YAML?

Yes for standard JSON values; YAML can represent the same arrays, objects, and scalar values.
