PerfectXL Risk Eliminator

Risk Inspections

Risk detection in spreadsheets is one of the essential features of PerfectXL Risk Eliminator. Currently the tool detects up to 75 types of risk, ranging from small risks to major problems. In cooperation with the Spreadsheet Department of Delft University of Technology, we keep expanding the list of detectable risks.

Risk Categories

Below you’ll find an overview of the risk categories that PerfectXL Risk Eliminator detects. Click a category to read more.

Hiding “unimportant information” from other users may seem like a good idea to make complex spreadsheets more user friendly. But in reality that’s not the case. Hidden information can be altered by a user, without him even realizing what he’s doing, resulting in potential negative results.

Excel does what you ask for, but are you asking the right question? We see many formulas that give us reason to doubt that. For example, when fixed numbers or double operators are used. This category of risks we call ‘calculation doubts’.

Larger spreadsheets are usually stuffed with formulas based on cell ranges. When spreadsheets are edited or expanded over time, different types of range issues may occur. These issues are usually hard to detect, but they can be very risky! We’ve seen big numbers and large sums of money ‘disappear’ because of range issues.

Currently Excel offers about 475 standard functions and new ones are added regularly. Most of these functions are rock-solid, but a couple of them we consider vulnerable functions. Some of which are frequently used by many Excel professionals. We suggest you try to avoid using them. Excel offers a range of fine alternatives.

The creation of a good structure is one of the most important, yet most underestimated aspects in the development of a spreadsheet. Usually a spreadsheet starts small, but then it grows and nobody gets around to reorganizing the structure anymore. PerfectXL Risk Eliminator groups the risks resulting from ill structure under ‘structure issues’.

The art of programming is the art of keeping things simple. Complex formulas are hardly ever wise to use. Calculations can usually be simplified. You just have to figure out how. PerfectXL points out different types of complex formulas in your spreadsheet and it offers suggestions to improve the complexity.

Excel is a powerful tool. And when it can’t do what you need, VBA can fill the gap. Unfortunately, using VBA can lead to unpredictable behaviour, slow performance, and corrupt Excel files. PerfectXL checks your macro-riddled spreadsheets for potential problems in the VBA code.
