What this tool does
YAML to JSON converts YAML configuration or data into JSON.
← All Tools
🔁 YAML to JSON Converter
Convert simple YAML into pretty-printed JSON in your browser.
Why it is useful
It helps developers inspect configs, prepare API payloads, and move structured data between tools.
How it works
The browser parses YAML and serializes equivalent values as JSON.
Best input
Paste valid YAML with careful indentation and complete documents.
Config tip
Review booleans, nulls, arrays, and strings because YAML parsing can surprise you.
Privacy note
Conversion happens locally in your browser.
Important limitation
YAML features such as anchors, tags, comments, and parser-specific behavior may not translate directly to JSON.
Quick answers
Do comments survive conversion?
No. JSON has no comments.
Why did a value type change?
YAML parsers infer booleans, numbers, nulls, and strings based on syntax.
