To disable updates to the Status Bar, use the Display Status Bar property as follows: If your macro is analyzing a lot of data, consider setting the Calculation property to Manual while the macro is running. Calculation = xl Calculation Automatic Macros can trigger unnecessary event procedures. In short, you simply combine the two statements and delete the Select method and the Selection object.That way, the workbook won't recalculate unless you force it to by pressing F9. Display Status Bar = False 'macro code Application. For instance, entering a value into a cell triggers the Worksheet_Change event. The optimized code is more efficient and less prone to runtime errors.Most of us use macros to automate processes that we repeat or that require specialized knowledge.Regardless of why you use macros, you want them to run as quickly as possible.Calculation speed probably isn't a large performance factor is most normal workbooks though, and it can have unexpected results, so use it sparingly—as needed: Application. A few won't be noticeable, but if the macro is complex enough, you might consider disabling events while the macro is running: Application. The commented lines show the Sheet and Table object references.The sheet reference is necessary only if you want to run the macro outside of the sheet (Divisions, in this case).You can optimize your code by: In this article, I'll show you how to make simple changes to your code to optimize it for speed.
This happens when Excel attempts to redraw the screen to show changes made by the running macro. If you use the macro recorder, you may have noticed that it's fond of using the Select method to explicitly reference things.
But we have fancy new ribbon icons, so all is well, right?
Next I learn that Excel uses SHA1 to encrypt spreadsheets instead of the previous method, which I assume was some sort of XOR with a one-character password.
If screen updates aren't necessary while running the macro, consider disabling this feature so your macro can run a bit faster. It works, but it's slow and prone to runtime errors. Then, review the resulting code for Select methods and change them to Range references.
Use the following statements to disable and enable this feature: Disabling screen updates won't disable the Status Bar, which displays information during normal operations, including what your macro is doing. For example, the following recorder code applies italics to C4: C62: Macro2() accomplishes the same thing with one line of code and without selecting the range.
