Thank u Miller for ur reply...
Actually I've tried to install the parseexcel and write excel modules using ppm also, But I'm getting some errors there also.
Anyway I'll read the CPAN documentation and will try it out again.

I'm using perl in windows 2000 OS.i'm using perl,v5.6.0 built for MSWin32-x86-multi-thread
i have two questions....
1) In an old thread I've read that to do this we need parseexcel and writeexcel modules which can be downloaded from cpan.
I've downloaded the two modules which are in zip format and unzipped them.When i tried to run the makefile, some warnings are coming that
->io:scalar.pm is a prerequisite it's not...
