String manipulation

Hi,

I need to modify the following string by adding the column Date to the string.

What is the easiest way to get this done? :slightsmile: Tried string manipulation, but was not able to get this to work :seeno_evil:

{ “fromdate”: “2000-01-01”, “todate”: “2030-12-31”,“asofdate”: $Date$,“datagroupings”: 4}
