Used to determine if we are passing valid JSON
Produces a Boolean Value..

I find this function useful when I'm trying to convert scripts with old parameters to utilize JSON scripting so that none of the old scripts break during the transition process:

IF[ IsValidJSON( Get(ScriptParameter)) ]
//create variables using new JSON scripting
//continue with old GetValue( Get(ScriptParameter), 1 ) variables
