XLSX read and dump

chirp84 has asked for the wisdom of the Perl Monks concerning the following question:

I am brand new to the perl community and am looking for help with a problem. I have 100+ files in .xlsx format in a folder and I want to dump only cells B37:B45 and C45:R45 from each file into a separate single file. I got the modules set up from CPAN on my new Mac OSX 10.7.2. I have had minor success with printing to an excel file and converting .xlsx to .csv after I saw how good the documentation was for different modules. However, I am not much closer to my end goal and feel like I've waded into the deep end. Can someone help me out please?

    Have you installed Spreadsheet::XLSX yet? If not, do that, then and read the documentation. It contains a simple program that opens a spreadsheet and dumps the contents. That should provide you with enough information that you'll be able to extract the data you want.

    Jump in, try it out, and let us know where you get stuck!

      Yes, I started with Spreadsheet::XLSX but got an error as below: IO error: opening test.xlsx for read : No such file or directory at /System/Library/Perl/Extras/5.12/Archive/Zip/Archive.pm line 546 Archive::Zip::Archive::read('Archive::Zip::Archive=HASH(0x7f87628288d8)', 'test.xlsx') called at /Library/Perl/5.12/Spreadsheet/XLSX.pm line 33 Spreadsheet::XLSX::new('Spreadsheet::XLSX', 'test.xlsx') called at parse.pl line 6 Cannot open test.xlsx as Zip archive at /Library/Perl/5.12/Spreadsheet/XLSX.pm line 33.

        First of all, a meta-comment: you should wrap your errors in code tags to a) make that part of it easier to read and b) make it stand out from the rest of your post. Ideally, the errors would look like

          IO error: opening test.xlsx for read : No such file or directory at /System/Library/Perl/Extras/5.12/Archive/ +Zip/Archive.pm line 546 Archive::Zip::Archive::read('Archive::Zip::Archive=HASH(0x7f87628288d8 +)', 'test.xlsx') called at /Library/Perl/5.12/Spreadsheet/XLSX.pm line 33 Spreadsheet::XLSX::new('Spreadsheet::XLSX', 'test.xlsx') called at parse.pl line 6 Cannot open test.xlsx as Zip archive at /Library/Perl/5.12/Spreadsheet +/XLSX.pm line 33
        I've added a few line breaks to make it easier to read.

        Second, it looks like (and I'm guessing, because you haven't posted any code yet) you are accessing the spreadsheet while it's inside a zip file. To make it easier, can you just extract one of the spreadsheets and operate on that?

        Let's try to solve one problem at a time (aka, "You've got to walk before you can run.")
