JSON Key Sorter

Sort object keys and arrays in a JSON document to make two versions comparable.

Sorting JSON keys puts a document into a canonical order so two versions can be compared meaningfully. Object key order is not significant in JSON, so a diff between differently-ordered documents is noise — sorting both first removes it.

Frequently asked questions

Is it safe to sort arrays?

Only when the order carries no meaning. In a list of tags it is fine; in a list of steps, a sequence of events, or anything positional, sorting destroys information. That is why it is off by default.
