How are keys sorted?

Keys are sorted alphabetically (lexicographic order) at every level of the YAML document, including nested objects. Array order is preserved.

Why sort YAML keys?

Sorted keys make YAML files more predictable and easier to diff. It reduces merge conflicts and improves readability in configuration files.

Does sorting change the data?

No, only the order of keys changes. All values, nested structures, and arrays remain exactly the same.

Is this tool free?

Yes, completely free with no signup or limits.
