I have several instances where I get null back for different datatypes, what I have to do is just to ignore the Errors from the JSON VIs.
So it will convert everything it can' but when trying to convert NULL to a string it will be empty or for an int it will be zero.
Ideally it would be good to be able to say when you find Null for:
A strings use "" or "NULL"
A INT use 0 or -1
For DBL/SGL it uses NaN and that is prefect.
There appeared to be an issue in the posted version of the library. I sent secr1973 the latest version and it is working for him.
I have attached the latest version of the library.
