Hi,
why are you using macros when it can be done with simple excel formulas
Try this, simple formulas
Simply select cell A1, Then copy all data from notepad and paste it into excel
Then click in cell C1 and type following formula =Len(A1)
then click in cell D1 and type following formula =Search(":",A1)
Now in cell E1 type =Left(A1,D1-1)
and In cell F1 type =Right(A1,C1-D1)
and Finally, Select cell E1 and F1 and drag them upto the bottom of the list
and You will get desired results
Hope,It solves your requirement.
In case you face any problem,feel free to PM me.
Thanks
