Whenever you have a task to automate, you can usually go down the VBA route. Maybe later you add some features here-and-there, making your VBA code more powerful. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) End Sub Before moving on, let’s get a better understanding of why this is taking so long. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) Application.
And usually when you write your code, you’re just trying to get things to work. But after a while you notice your code is beginning to get very slow when it runs. I mentioned that the issue is that the screen is constantly updating, which is causing the code to run slowly. The code runs much faster when there’s less real estate to update on your screen. Screen Updating = True End Sub Now the code runs at 1.4 seconds for me, which is a huge improvement.

Value Mod 2 = 0) Then ' if i is even, color the cell white cell. Range For repeat = 1 To 30 For Each cell In r cell. Value Mod 2 = 0) Then ' if i is even, color the cell white cell. This will speed up operations while also providing the user with a better and more tolerable experience. It will be specially usefull with those horrible macros made by the recorder, full of unnecessary "select" and "activate". I had a long-running macro several years ago that took almost a minute to run.Say, for example that you want to write some data to a sheet as fast as possible. RELEASE MEMORY ' turn on updates It depends on how much you are actually updating on the screen as part of your code, (i.e. Screen Updating = b Scrn Upd Exit Sub 'reset them even if you are exiting due to error lbl Error: Application. I set Screen Updating to false and it finished in less than 5 seconds.You could do this: ' turn off updates ' Organise data in ram so that it fits the range for which it is meant Dim two_d_arr (rows,cols) load Data From Source two_d_arr Dim destination Range as Range destination Range = Sheets(some Sheet). number of cells updated), and how many sheets are there, how many sheets/cells refer to sheet your code is updating and how many formulas are present in the whole workbook. Screen Updating = False '-----------------------My code Application. Just make sure you reset Screen Updating to true when you're finished running the macro.
Discover this word and many others that you can use in combination with Application in the downloadable course on Excel macros. As you can read: starting in cell A1 a value of "99" will be entered in the selected cell then the cursor will move one cell down to enter "99", repeat the process until the row number of the selected cell is 3000 and come back to cell A1.
