I have code that loads an Excel XLSX file into memory and then analyzes its content. However, when I load a very large file I run into the "Out of memory" error. Checking the Windows Task Manager I see that Perl is only using around 1GB and that there is memory left since my computer has 4GB of RAM.

This is how I read the file with one module:
