If you’re new to VBA and are wondering why your code is running very slowly, excessive use of the. Improve speed by keeping object selections to a minimum You should always use Option Explicit at the top of each code module before any of your routines.ħ. It highlights the undeclared variable and informs us of the problem. When the code in the second example is run, Option Explicit detects that we’ve undefined variables in our code and returns a Compile Error. Nothing divided by something is always zero. Why? The reason is that the variable MonthIncme is spelled incorrectly, and therefore references nothing. The code runs with no errors, but it always returns the answer of zero. In the left example below, Option Explicit is not enabled. Using “Option Explicit” at the start of a VBA code module is a valuable way to avoid spelling errors in your code. Use Option Explicit to avoid missing values Learning how to code yourself will allow you to create loops and search for the correct column before correctly deleting it.Ħ. Suppose then that next month, the file includes an additional column now your macro will delete the wrong column. Part way through the code, it selects column I, and then deletes it. Suppose you’ve recorded a macro that performs various formatting changes to your worksheet. It’s important to recognize, however, that macros are inherently unreliable and not future-proof because they are hard-coded and cannot adapt to future changes in your worksheet structure.

Learn to write your own code don’t rely on macros!Īs mentioned above, macros are incredibly helpful in learning how certain pieces of code are written. Magic! Now, you can reuse and adapt the code in your own routines.ĥ. By pressing Record Macro, you can carry out the steps manually, and the VBA editor will record those steps in code. Suppose you didn’t know how to save a file using VBA. Even for experienced coders, macros are a great way to quickly understand the VBA syntax needed to execute a particular function or method.

Planning the structure of your VBA, what you want it to achieve, what loops you’ll need etc. It’s not uncommon to get halfway through writing a code project before realizing that you should’ve structured it differently or created a separate function for specific elements of your code. Plan your work to help create simple, efficient VBA code Notice how much clearer the second example is than the first.ģ. The routine below pastes the US inflation rate into the active cell if it’s available.

Name variables and functions using clear and relevant names You’ll also impress colleagues and quickly gain a reputation for preparing outstanding documentation, thus reducing training time for future users.Ģ. Writing comments is the most important element of writing VBA code, and it will ensure that you can easily understand your own code a few months down the line.
