![]() ![]() Just one recalculation and one redraw at the end of your code execution is enough to get the workbook current with all your changes. ![]() One reason this helps is that if you’re updating (via VBA) several different ranges with new values, or copy / pasting from several ranges to create a consolidated table of data, you likely do not want to have Excel taking time and resources to recalculate formulas, display paste progress, or even redraw the grid, especially after every single operation (even more so if your code uses loops). Note that in the code sample below we grab the current state of these properties, turn them off, and then restore them at the end of code execution. This optimization explicitly turns off Excel functionality you don’t need to happen (over and over and over) while your code runs. Turn Off Everything But the Essentials While Your Code is Running If you think I missed an important concept for how to optimize Excel VBA performance, or if you’ve got a valuable comment or link to share, please feel free to post here so everyone can benefit. There are tons of sites, pages, and people who are experts as well on this subject, have performed their own tests, and shared their results and ideas. In this post I’m going to share with you the most important performance tips I know about. It is incredibly helpful to be able to look at what you all are doing with Excel! Not only did I see a huge variety in how Excel is being used, you also pointed out various tips and tricks for writing fast VBA code in Excel. I want to start off this post by thanking everyone who sent in their examples in response to my January request. Today’s author, Chad Rothschiller, a Program Manager on the Excel team, is back with a follow up from his previous post on VBA and Excel performance. ![]()
