In short: A JSON to YAML converter rewrites JSON's brace-and-bracket syntax as YAML's indentation-based syntax — same data, different format, which infrastructure tools like Kubernetes and Docker Compose expect. RealJSON's converter does this instantly in your browser with configurable indentation and smart string quoting.
JSON and YAML represent the same data structures but with very different syntax. JSON is the format of the web — API responses, SDKs, and config files often produce it. YAML is the format of infrastructure — Kubernetes manifests, Docker Compose files, Helm charts, GitHub Actions, and Ansible playbooks all use it.
This converter translates any valid JSON into properly indented YAML, running entirely in your browser. No data leaves your machine.
environment blockStrings that would be ambiguous in YAML (booleans, numbers, special characters) are automatically quoted. Plain strings without special characters are written unquoted for readability. The "force quote strings" option wraps every string value in quotes.
JSON arrays become YAML sequences with - list items. Nested objects become indented mappings. The structure is preserved exactly.
Choose 2-space (default, common in Kubernetes and Helm) or 4-space indentation to match your project's conventions.
Paste your JSON in. Properly indented YAML appears instantly — pick 2-space or 4-space indentation, then copy it or download as a .yaml file.
JSON is common in API responses and SDKs, but infrastructure tools like Kubernetes, Helm, Docker Compose, and GitHub Actions use YAML for configuration — converting lets you reuse JSON data directly in those formats.
Strings that would be ambiguous in YAML — looking like booleans, numbers, or containing special characters — are quoted automatically. Plain strings stay unquoted for readability, and a "force quote strings" option quotes everything.
Yes — arrays become YAML sequences with "-" list items, and nested objects become indented mappings. The structure is preserved exactly.
No. Conversion runs entirely in your browser — your data never leaves your machine.
If your JSON has errors, use the JSON Repair tool first. To generate test JSON before converting, try the Correlated JSON Generator.
