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 :

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.")

FYI, XLSX files ARE zipped. If you look at it in an editor or hex viewer, the first two characters are PK, which indicates it's a ZIP file (from PKZIP, the forerunner of modern ZIP, where PK stands for Phil Katz, who invented it).

If you run unzip (or pkunzip, etc.) on the file, it creates some directories that are full of XML files and RELS files (MS Office 2007+ relationship files). Any module working with an XLSX file would need to include something from the Archive::ZIP family.

That said, I don't work on a Mac, but I would have assumed Spreadsheet::XLSX would have installed Archive::Zip::Archive as a dependency. Maybe the OP should try installing it manually.

--marmot

The test.xlsx file isn't in a zip file. I thought it was going to create a new file called test.xlsx, but didn't. So then I tried renaming one of the files to test.xlsx and placed it in the same directory as the script below, named parse.pl, thinking that it would read it. Either way, I still get the same error about a zip archive.

use strict;
use warnings;

 use Spreadsheet::XLSX;
 
 my $excel = Spreadsheet::XLSX -> new ('test.xlsx');
 
 foreach my $sheet (@{$excel -> {Worksheet}}) {
 
        printf("Sheet: %s\n", $sheet->{Sheet1});
        
        $sheet -> {B45} ||= $sheet -> {B37};
        
         foreach my $row ($sheet -> {B37} .. $sheet -> {B45}) {
         
                $sheet -> {R45} ||= $sheet -> {C45};
                
                foreach my $col ($sheet -> {C45} ..  $sheet -> {R45}) 
+{
                
                        my $cell = $sheet -> {Cells} [$row] [$col];
 
                        if ($cell) {
                            printf("( %s , %s ) => %s\n", $row, $col, 
+$cell -> {Val});
                        }
 
                }
 
        }
 
 }
