PerfectXL Advanced Training

About the trainers

This course was designed by PerfectXL (Infotron) in collaboration with 11 of Microsoft’s designated “Most Valuable Professionals” and 3 of the most prestigious universities of the Netherlands. The Excel MVP’s have tens of years of experience with Excel and work with the biggest companies in the world.

PerfectXL

This course was designed, issued, and created by InfotronBV (the makers of PerfectXL). We are Excel experts and develop software solutions geared towards helping Excel users in a business setting. The ideas that fueled the company come from a study which originated at the Delft University of Technology. This study showed that over 80% of business critical spreadsheets contain mistakes of some kind. A team then started to develop software tools that reduce the risks associated to Excel models: PerfectXL. The tools do a great job of reducing risks, but we wanted to go a step further to create a training that helps users make better models from the start, rather than fixing flaws.
