Hi Ashok,
Macro is like a ghost in Excel, which automatically does all the manual work which you are supposed to do....
Macro is a very AMAZING TOOL .....for eg:- If a process takes you 1 hr or more in excel, you can automate it with help of macros. Macros will reduce to processing time from 1hr. to seconds (or milliseconds)....so perfect it is....
Almost everything what you do manually in excel can be done in macro...
Macro is not only limited to excel, it is also applicable to word, ppt and other office applications. Even your desktop can be operated with Macro. Desktop macros will record Keyboard or Mouse movements and repeat the same. For eg:- i used to open my lotus notes in office by just pressing a shortcut key which will trigger a desktop macro. That macro will go to start, programs, lotus notes, type my password and open my inbox and refresh it....(all within seconds)....
Excel Macros work only when excel is open. Hence to open excel and make the macro run, we had to use Desktop macro.
Simply MACRO is amazing feeling....it is wonderful to see excel working automatically...as you do........you can experience it by using it......start learning from today....
