Excel VBA Loop - EASY Excel Macros. Single Loop . A loop in Excel VBA enables you to loop through a range of cells with just a few codes lines. Single Loop. You can use a single loop to loop through a one- dimensional range of cells.

Place a command button on your worksheet and add the following code lines: Dim i As. Integer. For i = 1 To 6. Cells(i, 1). Value = 1. Next i. Result when you click the command button on the sheet: Explanation: The code lines between For and Next will be executed six times. For i = 1, Excel VBA enters the value 1. When Excel VBA reaches Next i, it increases i with 1 and jumps back to the For statement.

For i = 2, Excel VBA enters the value 1. Note: it is good practice to always indent (tab) the code between the words For and Next. This makes your code easier to read. Double Loop. You can use a double loop to loop through a two- dimensional range of cells.

Place a command button on your worksheet and add the following code lines: Dim i As. Integer, j As. Integer. For i = 1 To 6. For j = 1 To 2. Cells(i, j). Value = 1. Next j. Next i. Result when you click the command button on the sheet: Explanation: For i = 1 and j = 1, Excel VBA enters the value 1. When Excel VBA reaches Next j, it increases j with 1 and jumps back to the For j statement.

For i = 1 and j = 2, Excel VBA enters the value 1. Next, Excel VBA ignores Next j because j only runs from 1 to 2. When Excel VBA reaches Next i, it increases i with 1 and jumps back to the For i statement.

Tutorial: For Loops and While Loops. You will learn how to create For Loops and While Loops and when the appropriate time would be to use them in your program. Building a While Loop.

Place a command button on your worksheet and add the following code lines: Dim c As. Integer, i As. Integer, j As.

Integer. For c = 1 To 3. For i = 1 To 6. For j = 1 To 2. Worksheets(c). Cells(i, j).

Value = 1. 00. Next j. Next i. Next c. Explanation: The only change made compared to the code for the double loop is that we have added one more loop and added Worksheets(c). Download the Excel file to see this result. Do While Loop. Besides the For Next loop, there are other loops in Excel VBA.

For example, the Do While Loop. Code placed between Do While and Loop will be repeated as long as the part after Do While is true. Place a command button on your worksheet and add the following code lines: Dim i As Integer. Do. While i < 6.

Cells(i, 1). Value = 2. Loop. Result when you click the command button on the sheet: Explanation: as long as i is lower than 6, Excel VBA enters the value 2. In Excel VBA (and in other programming languages), the symbol '=' means becomes. It does not mean equal. So i = i + 1 means i becomes i + 1. In other words: take the present value of i and add 1 to it. For example, if i = 1, i becomes 1 + 1 = 2.

As a result, the value 2. A five times (not six because Excel VBA stops when i equals 6). Enter some numbers in column A. Place a command button on your worksheet and add the following code lines: Dim i As Integer. Do. While Cells(i, 1).

Value < > . Excel VBA stops when i equals 7 because Cells(7, 1). Value is empty. This is a great way to loop through any number of rows on a worksheet.
