YAML to JSON Converter

Convert YAML Documents to JSON Objects

Input + outputConvert YAML documents into JSON objects
Convert YAML to JSON

Convert YAML documents into JSON for APIs, configuration pipelines, and data processing. The converter accepts YAML strings, files, and multi-document YAML.

YAML Input Requirements

If conversion fails, check that the YAML follows the YAML specification. Common issues include:

  1. Make sure you do not have duplicate keys in your YAML.
  2. Make sure all keys and values are seperated by a colon (`:`).
  3. Make sure all array values have the appropriate minus sign and space (`- `) starting character.

For a deeper check, run the YAML Lint / Validate tool after conversion.

YAML Document Example

YAML documents convert to JSON objects. Example input:

name: "John Doe"
pets:
  - "fish"
  - "cat"
YAML Multi-Document Example

Multi-document YAML converts to a JSON array. Example input:

document: "this is document 1"
name: "John Doe"
---
document: "this is document 2"
name: "John Doe"
After Conversion

Use the JSON output in your application or API. For further processing, these tools can help:
