Introduction to the VBA For Loop
Loops are by far the most powerful component of VBA. They are the rocket fuel of your Macros. They can perform tasks in milliseconds that would have humans hours. They also dramatically reduce the lines of code your applications need.
For Loops take been part of all major programming languages since they were offset used with Fortan in 1957.
If yous have never used loops before then this postal service is a great place to offset. It provides an in-depth guide to loops, written in plainly English without the jargon.
Permit'southward outset with a very important question – what are loops and why do we demand them?
What are VBA For Loops?
A loop is simply a way of running the same lines of lawmaking a number of times. Obviously running the aforementioned code over and over would give the same issue.
So what is important to empathise is that the lines of code normally contain a variable that changes slightly each time the loop runs.
For example, a loop could write to cell A1, then prison cell A2, A3 then on. The slight modify each time is the row.
Let's look at a simple case.
VBA For Loop Example one
The following code prints the values 1 to v in the Firsthand Window(Ctrl + G to view).
Debug.Print 1 Debug.Print 2 Debug.Print 3 Debug.Print four Debug.Print 5
The Immediate Window
If you take not used the Immediate Window before and so this department will get you up to speed apace.
The role Debug.Print writes values to the Immediate Window. To view this window select View->Immediate Window from the menu( the shortcut is Ctrl + G)
VBA For Loop Example 2
At present imagine we want to print out the numbers i to 20. Nosotros would need to add fifteen more than lines to the instance above.
Nonetheless, using a loop we only need to write Debug.Print once.
For i = 1 To 20 Debug.Print i Adjacent i
The output is:
Output
If we needed print the numbers i to m then we but demand to alter the xx to 1000.
Normally when we write code we would use a variable instead of a number similar twenty or thousand. This gives you greater flexibility. Information technology allows yous to decide the number of times you wish to run the loop when the code is running. The following example explains this.
VBA For Loop Example 3
A common chore in Excel is read all the rows with with information.
The way you approach this task is as follows
- Find the last row with data
- Shop the value in variable
- Use the variable to decide how many times the loop runs
Using a variable in the loop makes your code very flexible. Your volition work no matter how many rows in that location are.
Permit's accept a look at an example. Imagine yous receive a sheet with a list of fruit types and their daily sales. You lot desire to count the number of Oranges sold and this listing volition vary in size depending on sales.
The following screenshot shows an example of this list
Sample Data of Fruit Sales
Nosotros can use the code to count the oranges
' https://excelmacromastery.com/ Sub CountFruit() ' Get the last row with text Dim LastRow As Long LastRow = Sheet1.Cells(Sheet1.Rows.Count, one).End(xlUp).Row Dim i Every bit Long, Full As Long ' Utilize LastRow in loop For i = 2 To LastRow ' Check if cell has text "Orange" If Sheet1.Cells(i, ane).Value = "Oranges" Then ' Add value in column B to full Total = Total + Sheet1.Cells(i, 2).Value End If Adjacent i ' Impress total Debug.Print "Total oranges sold was:"; Total End Sub
You can try this code for yourself. Change the number of fruit items and yous will encounter that the code still works fine.
If you were to increase the number fruit items to a large value like x,000 so y'all volition hardly notice the divergence in the time it takes to run – almost instantly.
Loops are super fast. This is what makes them and then powerful. Imagine performing a manual task on 10,000 cells. It would take a considerable amount of time.
Advantages of the VBA For Loop
4To conclude this section we will listing the major advantages of using loops
- They reduce the lines code you need
- They are flexible
- They are fast
In the next sections we will wait at the different types of loops and how to use them.
The Standard VBA For Loop
The VBA For loop is the nearly common loop you will use in Excel VBA. The For Loop is used when you tin can determine the number of times it will be run. For case, if you lot want to echo something twenty times.

Format of the Standard VBA For Loop
The Standard VBA For Loop has the following format:
For <variable> = <start value> to <terminate value>
Next <variable>
The get-go and end values can be variables. Likewise the variable later on Next is optional but it is useful and it makes it clear which for loop information technology belongs to.
How a For Loop Works
Permit'due south await at a simple for loop that prints the numbers 1 to iii
Dim i As Long For i = ane To 3 Debug.Print i Side by side i
How this code works is every bit follows
i is fix to i
The value of i(now one) is printed
i is set to 2
The value of i(now 2) is printed
i is set to 3
The value of i(now 3) is printed
If nosotros did non use a loop so the equivalent code would be
Dim i As Long i = i + 1 Debug.Impress i i = i + 1 Debug.Print i i = i + one Debug.Print i
The i = i + ane line is used to add one to i and is a mutual way in programming to update a counter.
Using Pace with the VBA For Loop
Y'all can see that i is increased by ane each fourth dimension. This is the default. Yous can specify this interval using Step keyword.
The next case shows you how to do this:
' Prints the even numbers i.e. two,iv,6,viii ... xx For i = two To 20 Stride two Debug.Impress i Next i
You tin can utilise a negative number with Step which will count in reverse
' Prints the even numbers in reverse i.east. 20,xviii,16,14 ... 2 For i = 20 To 2 Step -2 Debug.Impress i Next i
Annotation: if Step is positive then your starting number must be lower than you ending number. The following loop volition not run because the starting number xx is greater than x. VBA therefore, thinks it has already reached the target value 10.
' Will not run as starting number already greater than 10 For i = 20 To ten Step 1 Debug.Print i Adjacent i
If Pace is negative and then the start number must exist greater than the end number.
Exit the For Loop
Sometimes you lot may want to leave the loop earlier if a certain status occurs. For case if you read bad data.
You can use Exit For to automatically leave the loop as shown in the following code
For i = 1 To 1000 ' If cell is blank so go out for If Cells(i, i) = "" So MsgBox "Blank Cell institute - Data mistake" Leave For Stop If Next i
Using the VBA For Loop with a Collection
The For loop can likewise be used to read items in a Collection.
In the following example, we display the name of all the open workbooks
Dim i As Long For i = i To Workbooks.Count Debug.Impress Workbooks(i).FullName Adjacent i
Using Nested For Loops
Sometimes you lot may want to employ a loop within a loop. An example of this would be where you want to impress the names of the worksheets of each open workbook.
The first loop would go through each workbook. Each time this loop runs it would apply a second loop to go through all the worksheets of that workbook. It is actually much easier to practise than it sounds.
The post-obit code shows how:
' https://excelmacromastery.com/ Sub ListWorksheets() Dim i Equally Long, j As Long ' Commencement Loop goes through all workbooks For i = 1 To Workbooks.Count ' 2d loop goes through all the worksheets of workbook(i) For j = 1 To Workbooks(i).Worksheets.Count Debug.Print Workbooks(i).Name + ":" + Worksheets(j).Name Next j Next i Terminate Sub
This works every bit follows:
The offset loop sets i to ane
The 2d loop then uses the workbook at 1 to go through the worksheets.
The kickoff loop sets i to 2
The second loop then uses the workbook at 2 to go through the worksheets.
and so on
It the next section we will apply a For Each loop to perform the same job. You will find the For Each version much easier to read.
The VBA For Each Loop
The VBA For Each loop is used to read items from a collection or an array. We can utilize the For Each loop to admission all the open workbooks. This is considering Application.Workbooks is a collection of open up workbooks.
This is a simple example of using the For Each Loop
Dim wk Equally Workbook For Each wk In Workbooks Debug.Print wk.FullName Side by side wk
Format of the VBA For Each Loop
You lot can see the format of the VBA for each loop here(Run across Microsoft For Each Next documentation):
For Each <variable> in <collection>
Next <variable>
To create a For Each loop nosotros need a variable of the same type that the collection holds. In the example here we created a variable of type Workbook.
If the collection has different types of items we tin declare the variable as a variant.
VBA contains a drove called Sheets. This is a collection of sheets of blazon Worksheet(normal) and Chart(when you lot move a chart to exist a full sail). To go through this drove you would declare the variable as a Variant.
The following code uses For Each to print out the name of all the sheets in the electric current workbook
Dim sh Equally Variant For Each sh In ThisWorkbook.Sheets Debug.Print sh.Name Adjacent sh
Order of Items in the For Loop
For Each goes through items in one way but.
For instance, if yous go through all the worksheets in a workbook it will always become through from left to right. If you go through a range it volition kickoff at the lowest jail cell e.g. Range("A1:A10") volition return A1,A2,A3 etc.
This means if you desire any other guild then you need to utilise the For loop.
Both loops in the post-obit example volition read the worksheets from left to right:
' Both loops read the worksheets from left to right Dim wk As Worksheet For Each wk In ThisWorkbook.Worksheets Debug.Impress wk.Name Next Dim i Every bit Long For i = ane To ThisWorkbook.Worksheets.Count Debug.Impress ThisWorkbook.Worksheets(i).Name Next
As you lot can see the For Each loop is neater to write. However if you want to read the sheets in whatever other order eastward.k. right to left so you have to use the for loop:
' Reading the worksheets from correct to left Dim i As Long For i = ThisWorkbook.Worksheets.Count To 1 Stride -1 Debug.Impress ThisWorkbook.Worksheets(i).Proper name Next
Using the VBA For Each Loop With Arrays
One affair to keep in my is that the For Each loop is that it is read-simply when yous employ information technology with arrays.
The post-obit example demonstrates this:
' https://excelmacromastery.com/ Sub UseForEach() ' Create array and add 3 values Dim arr() As Variant arr = Array("A", "B", "C") Dim s As Variant For Each s In arr ' Changes what s is referring to - non value of array item s = "Z" Side by side ' Print items to prove the assortment has remained unchanged For Each s In arr Debug.Impress south Next End Sub
In the get-go loop we try to assign s to "Z". When happens is that due south is now referring the cord "Z" and no longer to the item in the array.
In the second loop we print out the array and y'all can come across that none of the values have changed.
When we apply the For Loop nosotros tin can change the assortment item. If we change the previous code to employ the For Loop you it volition change all the array values to "Z"
' https://excelmacromastery.com/ Sub UsingForWithArray() ' Create array and add three values Dim arr() As Variant arr = Array("A", "B", "C") Dim i As Long For i = LBound(arr) To UBound(arr) ' Changes value at position to Z arr(i) = "Z" Adjacent ' Print items to show the array values have change For i = LBound(arr) To UBound(arr) Debug.Print arr(i) Adjacent Finish Sub
If your Drove is storing Objects the you can modify the items using a For Each loop.
Using Nested For Each Loops
We saw already that you can have a loop inside other loops. Here is the example from above:
' https://excelmacromastery.com/ Sub ListWorksheets() Dim i As Long, j As Long ' Offset Loop goes through all workbooks For i = 1 To Workbooks.Count ' 2nd loop goes through all the worksheets of workbook(i) For j = 1 To Workbooks(i).Worksheets.Count Debug.Print Workbooks(i).Name + ":" + Worksheets(j).Name Next j Next i End Sub
This time we will utilise the For Each loop to perform the aforementioned job:
' https://excelmacromastery.com/ Sub ReadAllWorksheets() Dim wk As Workbook, sh As Worksheet ' Read each workbook For Each wk In Workbooks ' Read each worksheet in the wk workbook For Each sh In wk.Worksheets ' Impress workbook name and worksheet name Debug.Impress wk.Name + ": " + sh.Name Side by side sh Adjacent wk Finish Sub
As you can see this is a neater way of performing this task than using the For Loop:
This code run equally follows:
- Get the starting time Workbook from the Workbooks collection
- Go through all the worksheets in this workbook
- Print the workbook/worksheet details
- Get the next workbooks in the collection
- Repeat steps 2 to three
- Continue until no more workbooks are left in the collection
How to Loop Through a Range
In Excel VBA, the most common apply of a For Loop is to read through a range.
Imagine we have the data set in the screenshot beneath. Our task is to write code that will read through the data and copy the amounts to the cavalcade J. We are but going to copy amounts that are greater than 200,000.
The following example shows how nosotros do information technology:
' Read through an Excel Range using the VBA For Loop ' https://excelmacromastery.com/ Sub ForLoopThroughRange() ' Get the worksheet Dim sh As Worksheet Set sh = ThisWorkbook.Worksheets("Sheet1") ' Get the Range Dim rg As Range Set rg = sh.Range("A1").CurrentRegion ' Delete existing output sh.Range("J1").CurrentRegion.ClearContents ' Prepare the offset output row Dim row As Long row = one ' Read through all the rows using the For Loop Dim i Equally Long For i = 2 To rg.Rows.Count ' Check if amount is greater than 200000 If rg.Cells(i, 4).Value > 200000 Then ' Re-create amount to cavalcade m sh.Cells(row, "J").Value = rg.Cells(i, 4).Value ' Move to next output row row = row + 1 End If Adjacent i End Sub
This is a very bones example of copying information using Excel VBA. If y'all want a consummate guide to copying data using Excel VBA then cheque out this post
Summary of the VBA For Loops
The Standard VBA For Loop
- The For loop is slower than the For Each loop.
- The For loop can get through a selection of items e.1000. 5 to 10.
- The For loop can read items in reverse e.g. ten to one.
- The For loop is non every bit neat to write as the For Each Loop especially with nested loops.
- To exit a For loop utilise Exit For.
The VBA For Each Loop
- The For Each loop is faster than the For loop.
- The For Each loop goes through all items in the collection\array.
- The For Each loop tin can get through items in one guild just.
- The For Each loop is neater to write than a For Loop especially for nested loops.
- To leave a For Each loop use Exit For.
