JSON ↔ YAML Converter
Switch cleanly between JSON and YAML for configuration files, APIs, and development workflows.
Complete Guide & FAQ
What is the JSON ↔ YAML Converter?
It converts data structures between the two most widely used configuration formats in development: paste JSON and get its YAML equivalent, or paste YAML and get the corresponding JSON, instantly.
What it does
- JSON → YAML: ideal for turning API responses into readable configuration files.
- YAML → JSON: useful for consuming configuration files (Docker Compose, CI/CD) from code that expects JSON.
- Basic YAML support: maps, lists, and scalar values.
Frequently Asked Questions (FAQ)
Does it support advanced YAML features like anchors or multi-document files?
No, it supports basic YAML: maps, lists, and scalar values (text, numbers, booleans, and null). It covers the vast majority of configuration files (Docker Compose, GitHub Actions, etc.), but not advanced features of the full spec.
What happens if the YAML or JSON has a syntax error?
A conversion error message is shown describing the problem, without altering the previous result.
When should I use YAML instead of JSON?
YAML is more readable for hand-edited configuration files (no mandatory quotes or braces), while JSON is the standard format for data interchange between systems.
