I want automate my daily process, which is takes the data from text file and convert it into excel sheet. By using modules available in Perl I am able to create new excel sheet and writing data into it successfully and also I am able to read the data form excel sheet. But I want to append the data into an existing excel sheet, because my excel work book consists number of sheets and I want to update only two sheets and remaining sheets should be kept same.
Can any one help me in this aspect and tell me what are the modules available in the Perl to append data into an excel work book.
