YAML notes

  • • String value "1.0" was quoted to avoid YAML ambiguity.

Validation state

Valid

JSON is parsed safely with JSON.parse.

Indentation

2 spaces

Controls YAML nesting depth.

Key order

Preserved

Preserved by default unless sorting is enabled.

Output mode

Pretty

Clean YAML output for config and docs.

Local conversion

JSON is parsed and converted into YAML in your browser without backend calls.

Config-friendly output

Clean indentation and readable YAML for documentation and lightweight config prep.

Nested data support

Objects, arrays, booleans, numbers, strings, and null values are converted safely.

Dynamic Conversion Insights

Your JSON object was converted into YAML with 2-space indentation.
Your JSON object was converted into YAML mappings.
Key order was preserved from the original JSON.
Strings are quoted only when needed to avoid YAML ambiguity.
YAML indentation matters, so avoid changing leading spaces accidentally.

How JSON to YAML Conversion Works

JSON and YAML both represent structured data.

JSON uses braces, brackets, commas, and quoted keys.

YAML uses indentation and shorter syntax for mappings and lists.

JSON objects become YAML mappings, and JSON arrays become YAML lists.

JSON vs YAML Explained

JSON

Strict, compact, and common for APIs and machine-to-machine data exchange.

YAML

Readable, indentation-based, and common in human-edited configuration files.

Indentation, Arrays, Strings, and Comments Explained

YAML indentation defines nesting, so leading spaces matter.
Arrays usually use dash list items.
Strings may need quotes if they contain special characters or ambiguous values.
Booleans and nulls remain readable as true, false, and null.
JSON comments do not exist, so comments cannot be preserved.
Copied YAML should be validated before using it in production config files.

Config, DevOps, and API Use Cases

Converting API examples to YAML
Creating config snippets
Preparing Docker Compose-style examples
Preparing Kubernetes-style examples
Converting JSON settings for documentation
Preparing CI/CD config references
Converting structured data for tutorials
Cleaning developer examples
Transforming simple JSON exports

This converter changes data format only. It does not validate Docker, Kubernetes, CI/CD, or application-specific schemas.

Common JSON-to-YAML Examples

Simple JSON object to YAML mapping
JSON array to YAML list
Nested object to indented YAML
Booleans and null values
Array of objects
Strings that require quotes
Key order preserved
Sorted keys when enabled

Privacy and Local Processing Notes

Pasted JSON is processed locally in the browser.

No account is required, and no backend storage is added by this page.

Downloaded YAML is generated locally.

JSON content is parsed as data, not executed as code. No eval or unsafe parsing is used.

Avoid pasting sensitive production secrets unless necessary.

Method Explanation

  1. 1. Read the pasted JSON text.
  2. 2. Parse and validate the JSON safely.
  3. 3. Detect whether the top-level value is an object, array, or primitive.
  4. 4. Convert objects into YAML mappings.
  5. 5. Convert arrays into YAML list items.
  6. 6. Preserve booleans, numbers, strings, and nulls.
  7. 7. Apply indentation and quoting rules.
  8. 8. Copy or download the YAML output.
