Frequently Asked Questions

Sorted keys make configuration files easier to navigate, compare, and maintain. Consistent ordering reduces merge conflicts and helps find settings quickly.

Yes. All nested objects are sorted recursively. Each level of nesting gets its keys alphabetized while preserving the overall structure.

Array order is preserved by default. Arrays often have meaningful order (like priority or sequence) that shouldn't be changed. Objects within arrays are sorted.

Comments in YAML are not preserved during sorting. The tool parses YAML to data and regenerates it, which loses comments. Keep a backup if comments matter.

Yes, by default (uppercase before lowercase). You can choose case-insensitive sorting for more natural alphabetical order.

Yes. Invalid YAML produces parse errors. The tool shows error messages to help locate syntax issues before sorting.

Yes. All processing happens in your browser. No configuration data is sent to any server.

YAML anchors and aliases are resolved during parsing. The sorted output contains expanded values without anchor references.

Yes. Choose ascending (A-Z) or descending (Z-A) sort order. Descending puts Z keys before A keys.

The output uses consistent 2-space indentation. Original formatting variations are normalized during the sort process.
