JSON Sorter

A JSON sorter reorders the keys of a JSON object into alphabetical order and re-serialises the result. The values are untouched; only the order in which the keys appear changes, so {"name":"toolz","author":"Liton"} becomes {"author":"Liton","name":"toolz"}. Sorting is recursive by default, which means the keys inside every nested object are sorted too, all the way down.

Key order does not change what a JSON document means, because objects are defined as unordered collections of name-value pairs in the JSON standard, ECMA-404. But order matters a great deal to the humans and tools that read the text. A predictable, alphabetical order makes a config file easy to scan, keeps two files comparable, and produces stable diffs: when every export sorts its keys the same way, a version-control diff shows only the values that changed instead of noise from keys that merely moved.

This tool gives you control over how the sort runs. You can sort ascending (A to Z) or descending (Z to A), fold case so Name and name sit together, and choose whether to descend into nested objects or sort only the top level. Array order is preserved by default, because arrays are ordered by definition and reordering them can change meaning, but an option will sort arrays whose elements are all strings or all numbers when you do want them ordered. You can pretty-print the output with two-space, four-space, or tab indentation, or minify it to a single line.

Everything happens in your browser. The JSON is parsed, sorted, and re-serialised in JavaScript on your own machine, and nothing is uploaded, logged, or stored. That keeps API responses, configuration files, and payloads containing tokens or personal data on your device, and it means the tool keeps working offline once the page has loaded.
