i have a json string in a tag . this tag path should be used in another expression tag to extract individual values.  
eg: tag1={‘firstThing’:1, ‘secondThing’:2}  
tag2 = jsonGet(tag1 path,firstThing) #this is a expression tag under diffrent folder  
value should be 1  
i hope my question is clear .Any solution??

Tag3 value：

> {"first":13,"second":14}

New expression tag :

> jsonGet(jsonFormat({[.]Tag3}),"first")

Your tag1 value is string, not json object.
