Excel users may already realize how recorded macros can streamline redundant actions and boost their productivity. However many macro users don't realize that they can further refine their macros by editing them directly. Microsoft Excel courses can illustrate advanced techniques to take macros to the next level.

When a user records a macro, it creates a list of instructions that Excel can use to repeat the exact same actions. These instructions are written in a computer language called Visual Basic for Applications (VBA). VBA is designed to combine powerful programming commands with simple syntax that makes it easier to learn than most other computer languages.

Optimize recorded macros
Recording actions is a simple and powerful way to create macros but the method has limitations. Excel courses teach students how to open up the macro code, read it, and change it to refine its operation. Consider a macro used in creating invoices. The user wants it to enter the current date into the "Invoice Date" cell. There are two ways to do this with a recorded macro and neither of them will produce the desired result.

If you enter the current date, such as January 15, when recording the macro, it will always use that date as the invoice date even when entered on a different day. You'll have to manually change the invoice date every time.

However, if you enter a formula such as "Today()" to try and avoid the problem, that will enter the invoice date correctly but that date will be dynamic. That means that every time the invoice is loaded, the invoice date will change to the current date.

MS Excel courses can show you how to alter a recorded macro so that it calculates the correct invoice date as the date the invoice is created, then enters it as a static cell so that date will not change when the invoice is loaded later.

Create new commands
Although Excel contains a wide variety of built-in commands, you may have unique needs. Excel courses teach you how to build macros from scratch rather than by recording them, and how to make those macros available as new functions in formulas.

Consider the "Average()" command. It takes a group of values and displays their average. This is fine if you have clean data but outliers can invalidate the mean. "TrimMean()" can help, but it cuts off data whether they are outliers or not. MS courses can show you how to create a new command that can analyze each data point to see if it is an outlier or not and average only the sensible data to produce a more useful mean.

Find the right Microsoft courses
The power of macros can make them seem overwhelming even to experienced Excel users. Look into the Microsoft Excel courses offered and find the one appropriate to your level. You will learn a host of new techniques that will open up a universe of possibilities for Excel workbooks.
