Can it sort recursively?

Yes, toggle Recursive to sort keys at every nesting level.

Can it sort arrays of objects?

Yes, enable array sorting and provide a key to sort objects by, or leave it blank to sort primitive arrays directly.

What is natural sort order?

Natural sort compares embedded numbers numerically, so item2 comes before item10.
