FAQ
Common questions and answers about this topic.
What is the difference between YAML and JSON?
YAML uses indentation-based structure and supports comments, multi-line strings, and anchors/aliases. JSON uses curly braces and square brackets with strict quoting rules. JSON is more widely supported by APIs and programming languages.
Can I customize the JSON indentation?
Yes, JSON indentation can be set to 2 or 4 spaces, or tabs, via the formatting options. For JSON output, 2 spaces is compact while 4 spaces improves readability in deeply nested structures.
Can I sort the keys alphabetically?
Yes, use the sort keys dropdown to arrange all JSON object keys in alphabetical order (A to Z) or preserve the original sequence from your YAML input. The sorting is applied recursively through all nesting levels.
Is my data sent to any server?
No, the YAML-to-JSON conversion runs entirely in your browser. Your YAML data is processed locally with JavaScript and never transmitted to any external server.
