What license is this snippet available under?
does anyone know if there's a convertfrom-json implementation just like this one?
It seems to me that line 36 doesn't support enough numeric types. I prefer to remove lines 36 and 37 and insert these two lines at line 30, instead:
if ($value.GetType().Name -eq 'Boolean') {return "$value".ToLower()}
if ($value.GetType().IsPrimitive) {return "$value"}
This is crap. For a solution from a superior mind, see https://github.com/EliteLoser/ConvertTo-Json - but thanks for sharing.

Hi, This function works totally fine with me, But the problem is it is breaking the order of the elements in the JSON file being sorted alphabetically. So by running the following:
@{ "xx" = "sdfads" ; "a" = 2 } | ConvertTo-JSON
the result becoming:
{ "a": 2, "xx": "sdfads"}
So the original order xx,a is becoming a,xx
How to not sort the order of the elements? Can you suggest what I might need to change?
