I created 1 workbook named sara ver 7.0.xlxm that contains macros, around 50 sheets and contains so many formulae.
And i sent this to my friends all over State, all my friends downloaded and gave their school students data's.
After that i modified some changes in that workbook and named sara ver 7.1.xlxm.
If i send this new workbook to our friends, how can they updated the old workbook without loosing entered student data's.
How to do this?
Please give solution.
