Frequently asked questions
How to convert YAML to JSON online?
Type or paste your YAML content into the editor. The tool compiles the structure and outputs formatted, standard JSON instantly inside your browser.
Is my YAML data sent to a server for conversion?
No. The parsing and rendering run entirely on your local machine using client-side JavaScript. Your file data never leaves your device.
What happens to comments in the YAML file?
YAML comments (marked by #) are ignored by design when compiling to JSON, since the JSON format does not support native code comments.
How does the tool handle multiple documents in a single YAML file?
Multi-document YAML files (separated by ---) are parsed and converted into a structured JSON array containing each document as an object.
Can I customize the indentation of the output JSON?
By default, the tool outputs pretty-printed, indented JSON with two spaces for readability, which you can copy or download as a .json file.
