JSON ⇔ YAML Converter
Convert between JSON and YAML — useful for config file format conversion and data inspection.
How to use
- Paste JSON or YAML into the text area
- Press "JSON → YAML" or "YAML → JSON"
- The converted result appears below; use "Copy" to copy it
Conversion runs entirely in your browser using a YAML 1.2-compatible parser (js-yaml).
Example
Entering {"name": "Alice", "age": 30} and pressing "JSON → YAML" produces:
name: Alice
age: 30
FAQ
Are YAML comments and anchors (&/*) supported?
When converting YAML → JSON, comments are ignored and anchors/aliases are resolved to their expanded values. When converting JSON → YAML, comments are not emitted (JSON has no concept of comments).
What happens if conversion fails?
An error message is shown for invalid syntax.
Are multi-document YAML files (--- separated) supported?
No, only single-document YAML is supported.
Is my data stored anywhere?
No. Everything runs in your browser and disappears when you reload the page.
