TIL; When using Visual Studio ‘Find & Replace’, regex match groups used within the search term, can be referenced numerically in the replacement term using the $ symbol. The example below adds spaces between function parameters:
Test String
SomeFunctionCall(param1,param2,param3);
Search term
,(\w)
Replacement term
, $1
Result
SomeFunctionCall(param1, param2, param3);
