An VBA loop in Excel will execute an application or perform an action several times. The procedure (task) is able to be repeated on a variety of objects such as a range of cells, worksheet or workbook, an array or chart of a worksheet or worksheet, etc. Because a distinct program for every task must be developed, loops can be executed much faster as compared to manual repeating of the tasks.
For instance, VBA loops can be utilized to highlight cells that contain specific strings of text, erase empty rows from a data set as well as hide or unhide the worksheet, or open or close the workbook, change the colors of a graph, and many more.
Through loops, you can traverse the various items (elements) one at a time. Therefore, it’s possible to manipulate every element.
In VBA statements, they are executed in sequence. This means that the initial sentence is run first. It is then followed by the next one, then the third and then on. But VBA loops VBA loop runs and repeats one or a sequence of statements until an exact point has been reached.

Loops are typically utilized in all programming languages.
The top 4 types of VBA Loops
There are various types of loops that can be found in VBA. The four most popular loops are listed below:
For the Next VBA Loop
For Next loop lets you loop through a set of numbers, as well as a selection of objects. These include worksheets, cell ranges and workbooks, as well as shapes or other worksheet objects.
While looping through a number of cells exact procedure is carried out for each cell within the loop. For the For Next loop, the numbers that start and end the loop have to be noted.
By using this loop, also known as the For Next loop, the code block is executed for a certain quantity of repetitions. This loop should be utilized when the number of times (repetitions) that need to be carried out is predetermined.
For Each VBA Loop
For Each loop is also known as the For Each loop is also called the For Each-Next loop.
The For Every Loop
The use of VBA aids in looping the collection of objects. These include charts, worksheets and workbooks, as well as shapes, the range of cells and more.
By using the For Every loop, one is able to go through each item in the collection and complete tasks on it. For instance, one can complete tasks on each worksheet in the workbook. It could be to unhide or hide the worksheets.
For Each loop in Excel For Each VBA loop in Excel is utilized for situations where the total amount of items (or elements) within a collection is not identified. Thus, the amount of repetitions (repetitions) that need to be carried out is not known prior to the time.
Door While VBA Loop
It is a Do While loop repeats a statement or block of statements when a situation is fulfilled. Also the loop is running indefinitely as long as the condition is accurate. If the condition turns out to be false, the loop stops and VBA ends the loop.
The While condition is able to be tested either at the beginning or at the conclusion in the loop. This means that the condition can be tested prior to when the block is being executed, or following it.
The test of the While condition determines that the following:
- When the conditions are not true and the test is performed at the start of loop statements within the loop may not be executed even once.
- In the event that the assumption is not true and the test is conducted at the end of the loop the loop’s statements must be run at least one time.
An important note: A condition can be defined as any expression that is evaluated to Boolean values, whether true or false.
Do Until VBA Loop
It is the Do Until VBA loop in excel repeats a phrase or a set of statements until the specified circumstance is fulfilled. Also, the loop continues to run indefinitely if the condition is not true.
As with the While condition the Until condition may be tested at the beginning or the conclusion in the loop.
The test of the until condition reveals the following:
- When the conditions are true, and are tested at the beginning of the loop , statements within the loop could not be run more than once.
- When the conditions are true, and is verified at the conclusion of this loop then the statements within the loop will be run at least one time.
Note 1: To define the condition either While or Until can be employed. However, both can’t be used in conjunction.
Note 2: The repetition of statements is subject to the fulfilment or non-fulfillment of the condition.
