  • PerfectXL Compare currently only runs on windows PC’s, this is due to the fact that most intensive Excel users work on windows.
  • The Excel team is working on improving Excel for mac, but at this time the mac version of Excel simply doesn’t rival the functionality available in windows and that is why we develop all our software for windows specifically.
Supported file types
  • This tool supports all Excel files, also macro enabled files.
  • This tool does not support pictures, documents, pdf, csv, or other such files, excel files only


We have a great support team and are more than happy to answer any of your questions about our software, training, and services. Please note that we do not answer general Excel questions, our support team is dedicated to our products and services.
