This causes some additional overhead when your VBA code is executed especially if this variable is used often in your code: VBA is a dynamic typed language therefore you do not normally have to declare the type of your variable or declare variables in that matter. This will force you to explicitly declare the types of your variables. Add this option at the very beginning of your VBA project module or class.
Option Explicit requires that you declare ALL VARIABLES. It is not so much the presence of this macro that benefits your performance but the impact of the behavior it requires from you. This is because looping through Objects of a Collection is slower. ALWAYS use the For Each Loop when looping through Collections, Ranges etc. The For and For Each Loops are not equivalent and should be used in different situations. 'Instead if you want to copy just values do it directly 'Doing Range.Copy in a large loop will surely quickly increase Excel RAM Memory usage or the value, formatting, data validation etc. 'This uses up a lot of memory as it copies the everything associated with the Range The Excel Garbage Collecter unfortunately runs seemingly at specific intervals which means that if you create a lot of objects in a short amount of time you may run out of memory resulting in slowing down of Excel or simply crashing the application altogether Unfortunately in VBA we have limited control over the Garbage Collector – the mechanizm by which Excel will free up internal memory (declared unused variables, tables, objects etc.). The Excel Range.Copy procedure is a memory hog.

Run ApplicationDoEvents procedure to manually update the screen 'Turn off automatic ScreenUpdating (on demand). Prevent Excel from updating the Excel screen until this option is changed to True: Many case you will see a boost in VBA speed. Default value is xlCalculationAutomatic.Īpplication.Calculation = xlCalculationManual

'Set calculation mode to manual (on demand). To increase VBA speed of execution be sure to set the Calculation mode to xlCalculationManual so that no Excel formula calculations are carried out within the Excel Workbook until the Calculation mode is changed back to xlCalculationAutomatic or by running Application.Calculate: That is why I gathered all VBA performance guidelines into this single post which contains all the known ways of Improving VBA Performance, organized by impact on VBA Performance. What I personally was missing was a simple, comprehensive, short overview of how the performance of VBA macros can be improved without needing to read through long articles on how the Excel compiler works. There are many different articles and post on improving Excel performance.
