To achieve this, we can use Exit For statement.
Let's say we do not want to fill cells if i * j is more than 18.
You may want to exit a loop when a certain condition is met. Since j gets numbers between 2 and 6, only columns from B to F are filled. After this, i becomes 2 and j returns back to 2.

After code is executed in the j-loop, while i keeps its value (1), j becomes 3. In the first run, i becomes 1 and j becomes 2. In the statement panel, i and j are used as row and column numbers respectively. The following code contains 2 For.Next loops which is using variables named i and j. Let's see an example for nested For.Next loops. Otherwise, there will be leaps for the counter values. The important point is using different counter variables for each loop. You need three loops to fill a three-dimensional data array.
For example, while one loop is counting rows, other can count the columns. This type of structure can be helpful if you want add additional dimensions into your code. VBA executes all iterations in an inner loop, for each iteration of the outer loop. For example, For I = 10 To 1 Step -1 Example 3 – Nested Loops Remember to choose appropriate start and end arguments when you need to use a negative step value. In this loop, the variable i can only take "1, 3, 5, 7, 9" values. The following code is a modified version of the first example. Step can be either a positive or negative. To specify a step argument, use the Step keyword after the end argument and enter a number. You can change this property by using the step argument. Finally, the Next row increases the variable's row by 1, and cycle goes on until the variable is equal to 11.īy default, For.Next loop increases its counter variable by 1 for each loop. We used the variable to specify the row numbers and cell values. After the variable gets its value, you can use it in the code. In this code, For.Next loop sets values from 1 to 10 into the variable i.
Values in excel to octoparse loop serial numbers#
In the first example of For.Next loop, we attempt to write serial numbers into the cells in A1:A10. One or more statements between For and Next that are executed a specific number of times. Amount counter is changed each time through the loop. The variable can't be a Boolean or an array element. For example, if you want to check cells from A1 to A10, a counter clicks from 1 to 10 can work in that case. A For.Next loop is good for if you want to iterate you code certain amount of times, and for when you need to use the counter. A For loop is a basic concept of a loop structure in all programming languages. For.Next VBA Loopįor.Next (also known as For) loops are where you start to create VBA loops in Excel. However, you can modify and configure both loop types by their individual keywords. In generally, while For.Next loops are designed for specific amount of iterations, Do loops are good for iterating based on a condition.
The rest is up to your needs and imagination. For example, you may need to protect or unprotect every worksheet at once, iterate a calculation for a specific number of times, or loop cells and store their values into an array until you find an empty cell. VBA loops can be useful to automate tasks.

In this guide, we're going to show you how to create a VBA loop in Excel. A loop is an essential concept for programming. You can use loops to repeat an action until a specified condition is reached, or move through objects in a group, e.g. A loop is an essential concept for any programming language, and VBA follows the same approach.
