JSON ⇔ YAML Converter

Convert between JSON and YAML — useful for config file format conversion and data inspection.

How to use

  1. Paste JSON or YAML into the text area
  2. Press "JSON → YAML" or "YAML → JSON"
  3. 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.
