Paste or type JSON in the left panel and get clean, readable YAML on the right. Conversion is instant — no button to press. You can copy the result to clipboard or download it as a .yaml file.
YAML is less cluttered than JSON — no quotes around keys, no commas, and comments are supported. Docker Compose, Kubernetes, GitHub Actions, and Ansible all use YAML for exactly this reason: humans write and read these files constantly.
JSON is the better choice when code produces or consumes the data. APIs, databases, package managers, and SDKs all expect strict JSON. The implicit type coercion in YAML (where yes becomes true and bare numbers lose their quotes) is useful in config files but a liability in data exchange.
The conversion is straightforward — both formats share the same data model:
Input JSON:
{
"server": {
"host": "localhost",
"port": 8080,
"debug": true
},
"features": ["auth", "logging"]
}
Output YAML:
server:
host: localhost
port: 8080
debug: true
features:
- auth
- logging
Key differences in the output:
{} become indented blocks[] become - item sequences| JSON | YAML output | Notes |
|---|---|---|
"hello" | hello | Unquoted if safe |
"true" | "true" | Quoted to avoid boolean interpretation |
42 | 42 | Integer |
3.14 | 3.14 | Float |
true | true | Boolean |
null | null or ~ | Null |
{} | {} | Empty object |
[] | [] | Empty array |
Watch out for: string values that look like YAML booleans or numbers (e.g. "yes", "no", "1.0"). The converter wraps these in quotes automatically to prevent misinterpretation when the YAML is later parsed.
Paste your JSON into the left panel. The converter parses it and uses js-yaml to produce equivalent YAML in the right panel. The conversion is real-time — output updates as you edit.
Yes. Nested objects become indented YAML mappings, and JSON arrays become YAML sequences. All standard JSON types — strings, numbers, booleans, null, objects, and arrays — are handled correctly.
Yes — use the YAML to JSON tool on JSONbite. It supports the full YAML spec including anchors, aliases, and multi-line strings.
The data is identical. YAML drops the curly braces and square brackets used in JSON and replaces them with indentation. Quoted strings in JSON may appear unquoted in YAML if they don't need escaping.
No. JSON has no concept of comments, so there is nothing to carry over. The output is clean YAML with no comments. You can add comments manually after conversion.
No. Conversion happens entirely in your browser using the js-yaml library. Your data never leaves your machine.
