Cancel splitting column and return splitting to general

hello
I need macro to merge the column B,C,D into one column as the result in column G:I when run the macro from the first time and if I run again , then should return splitting column into multiple columns as the orginal data in columns A: E . the output should be in the same range in columns A: E .
thanks

How do we know if it is the first or any other run?

the first is the original data , my request as in undo after run the macro . it depends on two cases the orginal and the result in G:I , but the idea when run the macro repeatedly just show the orginal and the result ,if press first time then should show the result ,if I run again return the orginal .
I hope this is logical .
