Format API data
Paste JSON, choose indentation, then format. Sort keys and remove null values only when those changes are intended.
Example
{"b":2,"a":1} can be sorted into a before b. Removing nulls changes data, not only spacing.
Before you use the result
Invalid JSON must be corrected first. Review transformations before using the output.
