Privacy & Security
We take spreadsheet security serious. Spreadsheets can sometimes contain sensitive information, but it is still vital to validate them, especially in the case of important spreadsheets. All data traffic is transferred over a secure connection. We use SSL and an external signing company to verify the validity of any connection to PerfectXL. All spreadsheets and web requests are transferred over HTTPS to ensure integrity and authenticity. Gone is gone, when you delete your files they are completely removed from our servers.

Long ago, Excel was not as clever and advanced as today, but the so-called array functions have been around for a long time. However, most people do not know about them, and do not understand them.
Whenever possible, keep your Excel formulas short and simple. Avoid long formulas; they are harder to read, harder to understand, difficult to check and tough to improve.
Sometimes, you need to use the exact same formula, based on the same numbers, in several other formulas. You might be tempted to calculate this formula twice, but resist the temptation. Make sure that you calculate your formulas only once!
It is so tempting to merge cells in Excel so that they form a header above two or more columns. Yes, we must admit, it looks nice, but resist the temptation because it can be dangerous!
It’s a bad idea to leave standard Excel errors in your workbook. Take the time to clean up, because after a while, you no longer know whether you left a mistake consciously or if there is something wrong with your spreadsheet.
(Hidden) circular references occur when Excel tries to compute a result of a cell that’s already been visited during the calculation round. Excel doesn’t warn us of conditional circular references.
Sometimes a formula can spill over onto 2 or 3 lines making the standard 1 line formula bar too small to read. So how can you make formulas readable?
Among the infinite number of settings in Excel, one innocent looking option fundamentally changes the way Excel calculates formula results. It goes by the name Iterative calculation. This little known feature has its uses, but it doesn’t come without risk.
Place a formula close to its input variables. You reduce the chance of mistakes, you make optimal use of Excel’s support, and your spreadsheet becomes easier to carry over to someone else.
The use of hard coded numbers is a bad idea. A future user will not know where the number came from, and hard coded numbers don’t change automatically, and thus might be overlooked when a change is made.
Excel horror stories are often related to accidentally changing, shifting or changing units or number formats.
VLOOKUP and the combination of INDEX and MATCH are well known ways to search in Excel, and to our great frustration, VLOOKUP is used a lot more often.
Reporting is an integral part of Excel. Reports are generated in Excel, reports are built in Excel, and in many cases reports are a form of documentation required to properly use certain models in Excel.
Our software inspects spreadsheets on all kinds of spreadsheet risk. Read more about some of the risks we detect in spreadsheets here.
To be able to trust a spreadsheet, a thorough check for errors and mistakes is essential. There are lots of different ways a simple mistake can destroy the validity of a spreadsheet.
Good, error-free spreadsheets are essential for using them reliably in business. This is why risk detection is an important aspect of spreadsheet validation.
Do not hide anything except some sheets. Excel has too many attractive options that look good but may be risky in the long run.
