What we do

PerfectXL Add-in is software that you can download and install on your computer, it can be accessed from Excel. This software can be used to find risks and improve your understanding of Excel files. By using the tool directly in Excel you can quickly switch between getting information and solving issues/improving your Excel file.


  • PerfectXL Add-in currently only runs on windows PC’s, this is due to the fact that most intensive Excel users work on windows, and the Add-in is accessed from Excel.
  • 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. The add-in works directly in Excel and other file types cannot be analyzed.


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.


To get access to the tool you will need to contact us for a demo. We will then send you download information, either directly or to your IT department, you will also receive a username and password and will then have access to the software.
