YAML to JSON

YAML (YAML Ain't Markup Language) is a human-readable data serialization format designed to be clean and minimal. Instead of brackets and quotes, YAML uses indentation to show structure, making it popular for configuration files. It is used in Docker Compose, Kubernetes manifests, GitHub Actions, GitLab CI, Ansible playbooks, and Helm charts.

YAML and JSON represent the same data model — they can express the same structures. YAML is easier for humans to write and read (no brackets, no quotes required), while JSON is easier for machines to parse and is the standard for APIs. Converting YAML to JSON is a common need when you want to pass configuration data to a REST API, store it in a JSON database, or use tooling that only accepts JSON.

Input YAML:

user:
  name: Ravi Kumar
  age: 28
  active: true
  address:
    city: Surat
    country: IN
  tags:
    - developer
    - typescript

Output JSON:

{
  "user": {
    "name": "Ravi Kumar",
    "age": 28,
    "active": true,
    "address": { "city": "Surat", "country": "IN" },
    "tags": ["developer", "typescript"]
  }
}
