Frequently Asked Questions
Why would I convert YAML to JSON?
Most APIs expect JSON, not YAML. So if you've got data in YAML format (like Kubernetes configs, Docker Compose files, or CI/CD pipelines) and need to send it to an API or use it in JavaScript, you'll need JSON. Also, JSON is easier to work with programmatically in most languages.
What happens to YAML-specific features?
YAML has stuff JSON doesn't—like anchors, aliases, comments, and multi-line strings. When you convert, anchors and aliases get resolved into their actual values. Comments get stripped out since JSON doesn't support them. Multi-line strings become regular JSON strings with escaped newlines.
Does it handle complex YAML files?
Yeah. It works with nested objects, arrays, anchors, references, and all the standard YAML features. If your YAML is valid, the conversion should work fine. Just know that some YAML-specific formatting niceties won't carry over to JSON.
What if my YAML has errors?
You'll see an error message pointing to the problem. YAML is picky about indentation—mixing tabs and spaces or getting the indent wrong will break it. Fix the YAML syntax first, then the conversion will work.
Where does my data go?
Nowhere. Conversion happens in your browser using JavaScript. Your YAML file never gets uploaded to a server.
