Frequently asked questions
Does this tool upload my JSON?
No. The transformation runs in your browser. URL import contacts only the address you explicitly enter.
What happens when the JSON is invalid?
The editor marks the likely location and keeps stale output out of the result pane.
What does JSON Sorter produce?
It alphabetizes every object while leaving array positions unchanged.
What limitation applies to JSON Sorter?
Sorting changes textual key order, which may create a larger diff even though JSON object meaning is unchanged.
