About JSON to YAML Converter
Parse JSON before emitting YAML
The converter parses the input with JSON.parse, serializes the resulting object through the yaml library, then runs the YAML formatter. Invalid JSON is rejected before any YAML output is produced.
Prepare readable config files
Use it when moving API payloads or generated JSON settings into YAML-based files such as Kubernetes manifests, Docker Compose snippets, or CI configuration. Key sorting and indentation options help make the converted file easier to review.
FAQ
Common questions and answers about this topic.
What is the difference between JSON and YAML?
JSON uses curly braces and square brackets with strict quoting rules, while YAML uses indentation-based structure with a more human-readable syntax. YAML supports comments, multi-line strings, and anchors/aliases that JSON does not.
Can I customize the YAML indentation?
Yes, YAML indentation can be customized from 2 to 8 spaces using the formatting options above the input panel. Since YAML relies on whitespace for structure, 2 spaces is the most common convention.
Can I sort the keys alphabetically?
Yes, the sort keys dropdown lets you choose between keeping the original order or alphabetically sorting all YAML mapping keys (A to Z). This sorting is applied recursively through every nesting level.
Is my data sent to any server?
No, the JSON-to-YAML conversion runs entirely in your browser. Your JSON data is processed locally with JavaScript and never sent to any server.
