About this tool

Recursively sort mapping keys alphabetically while preserving scalar values, array order, and YAML document content. Paste data in the labeled format and review the example before processing a larger file or configuration. The parser validates structural requirements such as headers, rectangular rows, and required object fields. All transformations run locally in your browser; source data is not uploaded. Check the generated output in the context of your target application before committing it.

How to use this tool

  1. Paste input into the labeled field.
  2. Set the column, property, or range options when requested.
  3. Run the tool and verify the generated output.
