Online JSON to YAML / YAML to JSON Converter

Convert JSON to YAML or YAML to JSON online for API data and configuration files.

How to use

  1. Choose Auto / JSON / YAML beside the input heading. Auto prefers valid JSON; a manual format takes priority and reports syntax errors for that format. Clearing the input keeps the selected mode and output options. The result heading omits direction status; the converted data appears below.
  2. Use Format or Minify, 2 or 4 spaces and Sort keys beside the result title or in the expanded view.
  3. Syntax errors show their line and column. Go to error focuses and selects the input location. Copy exports content without line numbers.

Background knowledge

JSON
JSON is a text format representing data as key/value pairs and arrays. It uses braces, brackets and double quotes, and is common in API responses and data exchange.
YAML
YAML is a data format designed to be easy for people to read and write. It uses indentation and key: value notation, and is common in configuration files such as Kubernetes manifests.
JSON ↔ YAML
Format conversion reads data into a structure of keys, values and lists, then writes another notation. Single-line JSON and multiline YAML can represent the same data structure.

Notes

Frequently asked questions

What can I use this online tool for?

Convert JSON to YAML or YAML to JSON online for API data and configuration files.

What if the input is valid as both JSON and YAML?

Valid JSON takes priority and converts to YAML. Other valid YAML converts to JSON; JSON-like syntax errors are reported rather than silently treated as YAML.

Are YAML comments and special types preserved?

Comments and original formatting are not preserved. YAML-only types may not map to JSON, and cyclic data cannot be exported as JSON. Numbers follow JavaScript precision.
