For example, the following code references the same cell (value) six times: Function ReturnFeeSlow()Īt the very least, ReturnFeeSlow() makes two explicit references to I4. Similar to selecting ranges and objects to perform an action in the sheet, an explicit reference to the sheet also slows down processing.

To learn more about efficient selection methods when using VBA, read Excel tips: How to select cells and ranges efficiently using VBA. The Table references the Species column in a Table named Table3. The sheet reference is necessary only if you want to run the macro outside of the sheet (Divisions, in this case). The commented lines show the Sheet and Table object references. The optimized code is more efficient and less prone to runtime errors. In short, you simply combine the two statements and delete the Select method and the Selection object. Macro2() accomplishes the same thing with one line of code and without selecting the range. ' Sheets("Divisions").Range("C4:C62").Font.Italic = True Once you know the right methods and properties-Font.Italic = True-you can easily rewrite the macro as follows: Sub Macro2() The recorder uses the Select method to identify the range. For example, the following recorder code applies italics to C4:C62: Sub Macro1() Then, review the resulting code for Select methods and change them to Range references.
If you want to start with the recorder, do so. It works, but it's slow and prone to runtime errors. If you use the macro recorder, you may have noticed that it's fond of using the Select method to explicitly reference things.

A few won't be noticeable, but if the macro is complex enough, you might consider disabling events while the macro is running: Application.Calculation = xlCalculationManual For instance, entering a value into a cell triggers the Worksheet_Change event. Macros can trigger unnecessary event procedures. 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.Calculation = xlCalculationManualĪpplication.Calculation = xlCalculationAutomatic That way, the workbook won't recalculate unless you force it to by pressing F9.

If your macro is analyzing a lot of data, consider setting the Calculation property to Manual while the macro is running. To disable updates to the Status Bar, use the DisplayStatusBar property as follows: Application.ScreenUpdating = False You can expect Excel to redraw the screen when the macro completes its work-when you reset the property to True.ĭisabling screen updates won't disable the Status Bar, which displays information during normal operations, including what your macro is doing. Use the following statements to disable and enable this feature: Application.ScreenUpdating = False If screen updates aren't necessary while running the macro, consider disabling this feature so your macro can run a bit faster. Have you noticed that your screen sometimes flickers while a macro is running? This happens when Excel attempts to redraw the screen to show changes made by the running macro. There's no demonstration file you won't need one. The tips are specific to the desktop version because macros don't run in the browser version.
