Hi All,

I am using Windows XP -I have excel file where Sheet 1 has 500 rows &
15 columns of data
and similarly Sheet 2.
Excel is saved in the extenstion *.xls, Excel 2007 has new
Feature for saving the file in two different extension i.e., *.xlsx &
*.xlsm

Actually I do not have excel 2007 version but I can able to save *.xls
file in *.xlsm extension.
Storage used for *.xls file is 5.4 MB but for the same file saved in
*.xlsm has only 1.2 MB.

Is there any problem or drawbacks to convert *.xls files into *.xlsm....

I came to know *.xlsm can't be shared as I do not have excel 2007
version.

Kindly give me more information on this.

Thanks
Muddan Madhu
