Writing Data Into Existing Excel

[madan]

Dear All,

        I Have An Existing Excel Sheet On Linux And I Want To Embed
    Some Data Onto This Excel and Then Save It .. Is There Any Perl
    Script to Do This.

        I Went Through CPAN's Spreadsheet::WriteExcel , But This
    Overwrites The Existing Excel , Hence Old Data Inside Is Lost ,
    Pls. Help Me Out ..

Warm Regards,

Madan.
