Download/Export ALV in Web Dynpro

Hello Experts,

I got requirement to download ALV in webdynpro with format in which few of the columns should be read only and rest should be editable( in downloaded excel ).

It's easy to make ALV columns editable or read only but downloading ALV in same format in excel sheet is where we have stuck.

We can do the same in SAP GUI using OLE2 objects but these are not available in WD.

Kindly give suggestion whether it is possible or not and if its possible, how we can achieve this ?

Thanks,

Gaurav
