About Sort JSON Keys
This tool parses your JSON, sorts each object's keys alphabetically and recursively, then outputs it with 2-space indentation. Array element order is preserved.
Sorting keys makes two equivalent JSON documents look identical, produces stable diffs across versions, and makes large configs easier to read.
