Excel vba next do you

To get the most out of Excel and VBA, you need to know how to use loops efficiently.

In VBA, loops allow you to go through a set of objects/values and analyze it one by one. You can also perform specific tasks for each loop.

Here is a simple example of using VBA loops in Excel.

Suppose you have a dataset and you want to highlight all the cells in even rows. You can use a VBA loop to go through the range and analyze each cell row number. If it turns out to be even, you give it a color, else you leave it as is.

Now this, of course, is very simple of looping in Excel VBA (and you can also do this using conditional formatting).

In real life, you can do a lot more with VBA loops in Excel that can help you automate tasks.

Here are some more practical examples where VBA loops can be useful:

• Looping through a range of cells and analyzing each cell (highlight cells with a specific text in it).
• Looping through all the worksheets and do something with each (such as protect/unprotect it).
• Loop through all the open workbooks (and save each workbook or close all except the active workbook).
• Loop through all the characters in a cell (and extract the numeric part from a string).
• Loop through all the values an array.
• Loop through all the charts/objects (and give a border or change the background color).

Now to best use loops in Excel VBA, you need to know about the different kinds that exist and the correct syntax of each.

In this tutorial, I’ll showcase different types of Excel VBA loops and cover a few examples for each loop

Note: This is going to be a huge tutorial, where I will try and cover each VBA loop in some detail. I recommend you bookmark this page for future reference.

For Next Loop

The ‘For Next’ loop allows you to go through a block of code for the specified number of times.

For example, if I ask you to add the integers from 1 to 10 manually, you would add the first two numbers, then add the third number to the result, then add the fourth number to the result, as so on..

Isn’t it?

The same logic is used in the For Next loop in VBA.

You specify how many times you want the loop to run and also specify what you want the code to do each time the loop is run.

Below is the syntax of the For Next loop:

For Counter = Start To End [Step Value]
[Code Block to Execute]
Next [counter]

In the For Next loop, you can use a Counter (or any variable) that will be used to run the loop. This counter allows you to run this loop for a required number of times.

For example, if I want to add the first 10 positive integers, then my Counter value would be from 1 to 10.

Let’s have a look at a few examples to better understand how For Next loop works.

Example 1 – Adding the first 10 positive integers

Below is the code that will add the first 10 positive integers using a For Next loop.

It will then display a message box showing the sum of these numbers.

Sub AddNumbers()
Dim Total As Integer
Dim Count As Integer
Total = 0
For Count = 1 To 10
Total = Total + Count
Next Count
MsgBox Total
End Sub

In this code, the value of Total is set to 0 before getting into the For Next loop.

Once it gets into the loop, it holds the total value after every loop. So after the first loop, when Counter is 1, ‘Total’ value becomes 1, and after the second loop it becomes 3 (1+2), and so on.

And finally, when the loop ends, ‘Total’ variable has the sum of the first 10 positive integers.

A MsgBox then simply displays the result in a message box.

Example 2 – Adding the first 5 Even Positive Integers

To sum the first five even positive integers (i.e, 2,4,6,8, and 10), you need a similar code with a condition to only consider the even numbers and ignore the odd numbers.

Here is a code that will do it:

Sub AddEvenNumbers()
Dim Total As Integer
Dim Count As Integer
Total = 0
For Count = 2 To 10 Step 2
Total = Total + Count
Next Count
MsgBox Total
End Sub

Note that we started the Count value from 2 and also used ‘Step 2‘.

When you use ‘Step 2’, it tells the code to increment the ‘Count’ value by 2 every time the loop is run.

So the Count value starts from 2 and then becomes 4, 6, 8 and 10 as the looping occurs.

NOTE: Another way of doing this could be to run the loop from 1 to 10 and within the loop check whether the number is even or odd. However, using Step, in this case, is a more efficient way as it does not require the loop to run 10 times, but only 5 times.

The Step value can also be negative. In such as case, the Counter starts at a higher value and keeps getting decremented by the specified Step value.

Example 3 – Entering Serial Number in the Selected Cells

You can also use the For Next loop to go through a collection of objects (such as cells or worksheets or workbooks),

Here is an example that quickly enters serial numbers in all the selected cells.

Sub EnterSerialNumber()
Dim Rng As Range
Dim Counter As Integer
Dim RowCount As Integer
Set Rng = Selection
RowCount = Rng.Rows.Count
For Counter = 1 To RowCount
ActiveCell.Offset(Counter - 1, 0).Value = Counter
Next Counter
End Sub

The above code first counts the number of selected rows and then assigns this value to the variable RowCount. We then run the loop from ‘1 to RowCount’.

Also note that since selection can be any number of rows, we have Set the variable Rng to Selection (with the line ‘Set Rng = Selection’). Now we can use the ‘Rng’ variable to refer to the selection in our code.

Example 4 – Protect All Worksheets in the Active Workbook

You can use the ‘For Next’ loop to go through all the worksheets in the active workbook, and protect (or unprotect) each of the worksheets.

Below is the code that will do this:

Sub ProtectWorksheets()
Dim i As Integer
For i = 1 To ActiveWorkbook.Worksheets.Count
Worksheets(i).Protect
Next i
End Sub

The above code counts the number of sheets by using ActiveWorkbook.Worksheets.Count. This tells VBA how many times the loop needs to be run.

In each instance, it refers to the Ith workbook (using Worksheets(i)) and protects it.

You can use this same code to Unprotect worksheets too. Just change the line Worksheets(i).Protect to Worksheets(i).UnProtect.

Nested ‘For Next’ Loops

You can use nested ‘For Next’ loops to get more complex automation done in Excel. A nested ‘For Next’ loop would mean that there is a ‘For Next’ loop within a ‘For Next’ loop.

Let me show you how to use this using an example.

Suppose I have 5 workbooks open in my system and I want to protect all the worksheets in all these workbooks.

Below is the code that will do this:

Sub ProtectWorksheets()
Dim i As Integer
Dim j As Integer
For i = 1 To Workbooks.Count
For j = 1 To Workbooks(i).Worksheets.Count
Workbooks(i).Worksheets(j).Protect
Next j
Next i
End Sub

The above is a nested For Next loop as we have used one For Next loop within another.

‘EXIT For’ Statements in For Next Loops

‘Exit For’ statement allows you to exit the ‘For Next’ loop completely.

You can use it in cases where you want the For Next loop to end when a certain condition is met.

Let’s take an example where you have a set of numbers in Column A and you want to highlight all the negative numbers in red font. In this case, we need to analyze each cell for its value and then change the font color accordingly.

But to make the code more efficient, we can first check if there are any negative values in the list or not. If there are no negative values, we can use the Exit For the statement to simply come out of the code.

Below is the code that does this:

Sub HghlightNegative()
Dim Rng As Range
Set Rng = Range("A1", Range("A1").End(xlDown))
Counter = Rng.Count
For i = 1 To Counter
If WorksheetFunction.Min(Rng) >= 0 Then Exit For
If Rng(i).Value < 0 Then Rng(i).Font.Color = vbRed
Next i
End Sub

When you use the ‘Exit For’ statement within a nested ‘For Next’ loop, it will come out of the loop in which it is executed and go on to execute the next line in the code after the For Next loop.

For example, in the below code, the ‘Exit For’ statement will get you out of the inner loop, but the outer loop would continue to work.

Sub SampleCode()
For i = 1 To 10
For j = 1 to 10
Exit For
Next J
Next i
End Sub

Do While Loop

A ‘Do While’ loop allows you to check for a condition and run the loop while that condition is met (or is TRUE).

There are two types of syntax in the Do While Loop.

Do [While condition]
[Code block to Execute]
Loop

and

Do
[Code block to Execute]
Loop [While condition]

The difference between these two is that in the first, the While condition is checked first before any code block is executed, and in the second case, the code block is executed first and then the While condition is checked.

This means that if the While condition is False is both the cases, the code will still run at least once in the second case (as the ‘While’ condition is checked after the code has been executed once).

Now let’s see some examples of using Do While loops in VBA.

Example 1 – Add First 10 Positive Integers using VBA

Suppose you want to add the first ten positive integers using the Do While loop in VBA.

To do this, you can use the Do While loop until the next number is less than or equal to 10. As soon as the number is greater than 1o, your loop would stop.

Here is the VBA code that will run this Do While loop and the show the result in a message box.

Sub AddFirst10PositiveIntegers()
Dim i As Integer
i = 1
Do While i <= 10
Result = Result + i
i = i + 1
Loop
MsgBox Result
End Sub

The above loop continues to work until the value of ‘i’ becomes 11. As soon as it becomes 11, the loop ends (as the While condition becomes False).

Within the loop, we have used a Result variable that holds the final value Once the loop is completed, a message box shows the value of the ‘Result’ variable.

Example 2 –  Enter Dates For the Current Month

Let’s say you want to enter all the dates of the current month into a worksheet column.

You can do that by using the following Do While loop code:

Sub EnterCurrentMonthDates()
Dim CMDate As Date
Dim i As Integer
i = 0
CMDate = DateSerial(Year(Date), Month(Date), 1)
Do While Month(CMDate) = Month(Date)
Range("A1").Offset(i, 0) = CMDate
i = i + 1
CMDate = CMDate + 1
Loop
End Sub

The above code would enter all the dates in the first column of the worksheet (starting from A1). The loops continue till the Month value of the variable ‘CMDate’ matches that of the current month.

Exit Do Statement

You can use the Exit Do statement to come out of the loop. As soon as the code executes the ‘Exit Do’ line, it comes out of the Do While loop and passes the control to the next line right after the loop.

For example, if you want to enter the first 10 dates only, then you can exit the loop as soon as the first 10 dates are entered.

The below code will do this:

Sub EnterCurrentMonthDates()
Dim CMDate As Date
Dim i As Integer
i = 0
CMDate = DateSerial(Year(Date), Month(Date), 1)
Do While Month(CMDate) = Month(Date)
Range("A1").Offset(i, 0) = CMDate
i = i + 1
If i >= 10 Then Exit Do
CMDate = CMDate + 1
Loop
End Sub

In the above code, the IF statement is used to check if the value of i is greater than 10 or not. As soon as the value of ‘i’ becomes 10, Exit Do statement is executed and the loop ends.

Do Until Loop

‘Do Until’ loops are very much like the ‘Do While’ loops.

In ‘Do While’, the loop runs till the given condition is met, while in ‘Do Until’, it loops until the specified condition is met.

There are two types of syntax in the Do Until Loop.

Do [Until condition]
[Code block to Execute]
Loop

and

Do
[Code block to Execute]
Loop [Until condition]

The difference between these two is that in the first, the Until condition is checked first before any code block is executed, and in the second case, the code block is executed first and then the Until condition is checked.

This means that if the Until condition is TRUE is both cases, the code will still run at least once in the second case (as the ‘Until’ condition is checked after the code has been executed once).

Now let’s see some examples of using Do Until loops in VBA.

Note: All the examples for Do Until are the same as that of Do While. These have been modified to show you how the Do Until loop works.

Example 1 – Add First 10 Positive Integers using VBA

Suppose you want to add the first ten positive integers using the Do Until loop in VBA.

To do this, you need to run the loop until the next number is less than or equal to 10. As soon as the number is greater than 1o, your loop would stop.

Here is the VBA code that will run this loop and show the result in a message box.

Sub AddFirst10PositiveIntegers()
Dim i As Integer
i = 1
Do Until i > 10
Result = Result + i
i = i + 1
Loop
MsgBox Result
End Sub

The above loop continues to work until the value of ‘i’ becomes 11. As soon as it becomes 11, the loop ends (as the ‘Until’ condition becomes True).

Example 2 –  Enter Dates For the Current Month

Let’s say you want to enter all the dates of the current month into a worksheet column.

You can do that by using the following Do Until loop code:

Sub EnterCurrentMonthDates()
Dim CMDate As Date
Dim i As Integer
i = 0
CMDate = DateSerial(Year(Date), Month(Date), 1)
Do Until Month(CMDate) <> Month(Date)
Range("A1").Offset(i, 0) = CMDate
i = i + 1
CMDate = CMDate + 1
Loop
End Sub

The above code would enter all the dates in the first column of the worksheet (starting from A1). The loop continues until the Month of variable CMDate is not equal to that of the current month.

Exit Do Statement

You can use the ‘Exit Do’ statement to come out of the loop.

As soon as the code executes the ‘Exit Do’ line, it comes out of the Do Until loop and passes the control to the next line right after the loop.

For example, if you want to enter the first 10 dates only, then you can exit the loop as soon as the first 10 dates are entered.

The below code will do this:

Sub EnterCurrentMonthDates()
Dim CMDate As Date
Dim i As Integer
i = 0
CMDate = DateSerial(Year(Date), Month(Date), 1)
Do Until Month(CMDate) <> Month(Date)
Range("A1").Offset(i, 0) = CMDate
i = i + 1
If i >= 10 Then Exit Do
CMDate = CMDate + 1
Loop
End Sub

In the above code, as soon as the value of ‘i’ becomes 10, Exit Do statment is executed and the loop ends.

For Each

In VBA, you can loop through a set of collections using the ‘For Each’ loop.

Here are some examples of collections in Excel VBA:

• A collection of all the open Workbooks.
• A collection of all worksheets in a workbook.
• A collection of all the cells in a range of selected cells.
• A collection of all the charts or shapes in the workbook.

Using the ‘For Each’ loop, you can go through each of the objects in a collection and perform some action on it.

For example, you can go through all the worksheets in a workbook and protect these, or you can go through all the cells in the selection and change the formatting.

With the ‘For Each’ loop (also referred to as the ‘For Each-Next’ loop), you don’t need to know how many objects are there in a collection.

‘For Each’ loop would automatically go through each object and perform the specified action. For example, if you want to protect all the worksheets in a workbook, the code would be the same whether you have a workbook with 3 worksheets or 30 worksheets.

Here is the syntax of For Each-Next loop in Excel VBA.

For Each element In collection
[Code Block to Execute]
Next [element]

Now let’s see a couple of examples of using the For Each Loop in Excel.

Example 1 – Go through All the Worksheets in a Workbook (and Protect it)

Suppose you have a workbook where you want to protect all the worksheets.

Below For Each-Next loop can do this easily:

Sub ProtectSheets()
Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
ws.Protect
Next ws
End Sub

In the above code, we have defined ‘ws’ variable as a Worksheet object. This tells VBA that ‘ws’ should be interpreted as a worksheet object in the code.

Now we use the ‘For Each’ statement to go through each ‘ws’ (which is a worksheet object) in the collection of all the worksheets in the active workbook (given by ActiveWorkbook.Worksheets).

Note that unlike other loops where we have tried to protect all the worksheets in a workbook, here we don’t need to worry about how many worksheets are there in the workbook.

We don’t need to count these to run the loop. For Each loop ensures that all the objects are analyzed one by one.

Example 2 – Go through All the Open Workbooks (and Save All)

If you work with multiple workbooks at the same time, it can come in handy to be able to save all these workbooks at once.

Below VBA code can do this for us:

Sub SaveAllWorkbooks()
Dim wb As Workbook
For Each wb In Workbooks
wb.Save
Next wb
End Sub

Note that in this code, you don’t get a prompt that asks you to save the workbook in a specific location (if saving it for the first time).

It saves it in the default folder (it was the ‘Documents’ folder in my case). This code works best when these files are already saved and you’re making changes and you want to save all the workbooks quickly.

Example 3 – Go through All the Cells in a Selection (Highlight negative values)

Using the ‘For Each’ loop, you can loop through all the cells in a specific range or in the selected range.

This can be helpful when you want to analyze each cell and perform an action based on it.

For example, below is the code that will go through all the cells in the selection and change the cell color of the cells with negative values to red.

Sub HighlightNegativeCells()
Dim Cll As Range
For Each Cll In Selection
If Cll.Value < 0 Then
Cll.Interior.Color = vbRed
End If
Next Cll
End Sub

(Note I’ve used Cll as a short variable name for Cell. It’s advisable not to use object names such as Sheets or Range as variable names)

In the above code, the For Each-Next loop goes through the collection of cells in the selection. IF statement is used to identify if the cell value is negative or not. In case it is, the cell is given a red interior color, else it goes to the next cell.

In case you don’t have a selection, and instead want VBA to select all the filled cells in a column, starting from a specific cell (just like we use Control + Shift + Down arrow key to select all filled cells), you can use the below code:

Sub HighlightNegativeCells()
Dim Cll As Range
Dim Rng As Range
Set Rng = Range("A1", Range("A1").End(xlDown))
For Each Cll In Rng
If Cll.Value < 0 Then
Cll.Interior.Color = vbRed
End If
Next Cll
End Sub

In the above example, it doesn’t matter how many filled cells are there. It will start from cell A1 and analyze all the contiguous filled cells in the column.

You also don’t need to have cell A1 selected. You can have any far-off cell selected and when the code runs, it will still consider all the cells in column A (starting from A1) and color the negative cells.

‘Exit For’ Statment

You can use the ‘Exit For’ statement in the For Each-Next loop to come out of the loop. This is usually done in case a specific condition is met.

For example, in Example 3, as we are going through a set of cells, it can be more efficient to check if there are any negative values or not. In case there are no negative values, we can simply exit the loop and save some VBA processing time.

Below is the VBA code that will do this:

Sub HighlightNegativeCells()
Dim Cll As Range
For Each Cll In Selection
If WorksheetFunction.Min(Selection) >= 0 Then Exit For
If Cll.Value < 0 Then
Cll.Interior.Color = vbRed
End If
Next Cll
End Sub

Where to Put the VBA Code

Wondering where the VBA code goes in your Excel workbook?

Excel has a VBA backend called the VBA editor. You need to copy and paste the code in the VB Editor module code window.

Here are the steps to do this:

1. Go to the Developer tab.
2. Click on the Visual Basic option. This will open the VB editor in the backend.
3. In the Project Explorer pane in the VB Editor, right-click on any object for the workbook in which you want to insert the code. If you don’t see the Project Explorer go to the View tab and click on Project Explorer.
4. Go to Insert and click on Module. This will insert a module object for your workbook.
5. Copy and paste the code in the module window.

To work effectively in VBA, you must understand Loops.

Loops allow you to repeat a code block a set number of times or repeat a code block on a each object in a set of objects.

First we will show you a few examples to show you what loops are capable of. Then we will teach you everything about loops.

VBA Loop Quick Examples

For Each Loops

For Each Loops loop through every object in a collection, such as every worksheet in workbook or every cell in a range.

Loop Through all Worksheets in Workbook

This code will loop through all worksheets in the workbook, unhiding each sheet:

Sub LoopThroughSheets()
Dim ws As Worksheet
 
    For Each ws In Worksheets
        ws.Visible = True
    Next
 
End Sub

Loop Through All Cells in Range

This code will loop through a range of cells, testing if the cell value is negative, positive, or zero:

Sub If_Loop()
Dim Cell as Range
 
  For Each Cell In Range("A2:A6")
    If Cell.Value > 0 Then
      Cell.Offset(0, 1).Value = "Positive"
    ElseIf Cell.Value < 0 Then
      Cell.Offset(0, 1).Value = "Negative"
    Else
      Cell.Offset(0, 1).Value = "Zero"
     End If
  Next Cell
 
End Sub

For Next Loops

Another type of “For” Loop is the For Next Loop.  The For Next Loop allows you to loop through integers.

This code will loop through integers 1 through 10, displaying each with a message box:

Sub ForLoop()
    Dim i As Integer
    For i = 1 To 10
        MsgBox i
    Next i
End Sub

Do While Loops

Do While Loops will loop while a condition is met. This code will also loop through integers 1 through 10, displaying each with a message box.

Sub DoWhileLoop()
    Dim n As Integer
    n = 1
    Do While n < 11
        MsgBox n
        n = n + 1
    Loop
End Sub

Do Until Loops

Conversely, Do Until Loops will loop until a condition is met. This code does the same thing as the previous two examples.

Sub DoUntilLoop()
    Dim n As Integer
    n = 1
    Do Until n >= 10
        MsgBox n
        n = n + 1
    Loop
End Sub

We will discuss this below, but you need to be extremely careful when creating Do While or Do Until loops so that you don’t create a never ending loop.

VBA Loop Builder

This is a screenshot of the “Loop Builder” from our Premium VBA Add-in: AutoMacro. The Loop Builder allows you to quickly and easily build loops to loop through different objects, or numbers. You can perform actions on each object and/or select only objects that meet certain criteria.

The add-in also contains many other code builders, an extensive VBA code library, and an assortment of coding tools. It’s a must have for any VBA developer.

Now we will cover the different types of loops in depth.

VBA For Next Loop

For Loop Syntax

The For Next Loop allows you to repeat a block of code a specified number of times. The syntax is:

[Dim Counter as Integer]

For Counter = Start to End [Step Value]
    [Do Something]
Next [Counter]

Where the items in brackets are optional.

• [Dim Counter as Long] – Declares the counter variable. Required if Option Explicit is declared at the top of your module.
• Counter – An integer variable used to count
• Start – The start value (Ex. 1)
• End – The end value (Ex. 10)
• [Step Value] – Allows you to count every n integers instead of every 1 integer. You can also go in reverse with a negative value (ex. Step -1)
• [Do Something] – The code that will repeat
• Next [Counter] – Closing statement to the For Next Loop. You can include the Counter or not. However, I strongly recommend including the counter as it makes your code easier to read.

If that’s confusing, don’t worry. We will review some examples:

Count to 10

This code will count to 10 using a For-Next Loop:

Sub ForEach_CountTo10()

Dim n As Integer
For n = 1 To 10
    MsgBox n
Next n

End Sub

For Loop Step

Count to 10 – Only Even Numbers

This code will count to 10 only counting even numbers:

Sub ForEach_CountTo10_Even()

Dim n As Integer
For n = 2 To 10 Step 2
    MsgBox n
Next n

End Sub

Notice we added “Step 2”. This tells the For Loop to “step” through the counter by 2.  We can also use a negative step value to step in reverse:

VBA Programming | Code Generator does work for you!

For Loop Step – Inverse

Countdown from 10

This code will countdown from 10:

Sub ForEach_Countdown_Inverse()

Dim n As Integer
For n = 10 To 1 Step -1
    MsgBox n
Next n
MsgBox "Lift Off"

End Sub

Delete Rows if Cell is Blank

I’ve most frequently used a negative step For-Loop to loop through ranges of cells, deleting rows that meet certain criteria.  If you loop from the top rows to the bottom rows, as you delete rows you will mess up your counter.

This example will delete rows with blank cells (starting from the bottom row):

Sub ForEach_DeleteRows_BlankCells()

Dim n As Integer
For n = 10 To 1 Step -1
    If Range("a" & n).Value = "" Then
        Range("a" & n).EntireRow.Delete
    End If
Next n

End Sub

Nested For Loop

You can “nest” one For Loop inside another For Loop. We will use Nested For Loops to create a multiplication table:

Sub Nested_ForEach_MultiplicationTable()

Dim row As Integer, col As Integer

For row = 1 To 9
    For col = 1 To 9
        Cells(row + 1, col + 1).Value = row * col
    Next col
Next row

End Sub

Exit For

The Exit For statement allows you to exit a For Next loop immediately.

You would usually use Exit For along with an If Statement, exiting the For Next Loop if a certain condition is met.

For example, you might use a For Loop to find a cell. Once that cell is found, you can exit the loop to speed up your code.

This code will loop through rows 1 to 1000, looking for “error” in column A. If it’s found, the code will select the cell, alert you to the found error, and exit the loop:

Sub ExitFor_Loop()

Dim i As Integer
 
For i = 1 To 1000
    If Range("A" & i).Value = "error" Then
        Range("A" & i).Select
        MsgBox "Error Found"
        Exit For
    End If
Next i

End Sub

Important: In the case of Nested For Loops, Exit For only exits the current For Loop, not all active Loops.

Continue For

VBA does not have the “Continue” command that’s found in Visual Basic. Instead, you will need to use “Exit”.

VBA For Each Loop

The VBA For Each Loop will loop through all objects in a collection:

• All cells in a range
• All worksheets in a workbook
• All shapes in a worksheet
• All open workbooks

You can also use Nested For Each Loops to:

• All cells in a range on all worksheets
• All shapes on all worksheets
• All sheets in all open workbooks
• and so on…

The syntax is:

For Each Object in Collection
[Do Something]
Next [Object]

Where:

• Object – Variable representing a Range, Worksheet, Workbook, Shape, etc. (ex. rng)
• Collection – Collection of objects (ex. Range(“a1:a10”)
• [Do Something] – Code block to run on each object
• Next [Object] – Closing statement. [Object] is optional, however strongly recommended.

For Each Cell in Range

This code will loop through each cell in a range:

Sub ForEachCell_inRange()

Dim cell As Range

For Each cell In Range("a1:a10")
    cell.Value = cell.Offset(0,1).Value
Next cell

End Sub

For Each Worksheet in Workbook

This code will loop through all worksheets in a workbook, unprotecting each sheet:

Sub ForEachSheet_inWorkbook()

Dim ws As Worksheet

For Each ws In Worksheets
    ws.Unprotect "password"
Next ws

End Sub

For Each Open Workbook

This code will save and close all open workbooks:

Sub ForEachWB_inWorkbooks()

Dim wb As Workbook

For Each wb In Workbooks
    wb.Close SaveChanges:=True
Next wb

End Sub

AutoMacro | Ultimate VBA Add-in | Click for Free Trial!

For Each Shape in Worksheet

This code will delete all shapes in the active sheet.

Sub ForEachShape()

Dim shp As Shape

For Each shp In ActiveSheet.Shapes
    shp.Delete
Next shp

End Sub

For Each Shape in Each Worksheet in Workbook

You can also nest For Each Loops. Here we will loop through all shapes in all worksheets in the active workbook:

Sub ForEachShape_inAllWorksheets()

Dim shp As Shape, ws As Worksheet

For Each ws In Worksheets
    For Each shp In ws.Shapes
        shp.Delete
    Next shp
Next ws

End Sub

For Each – IF Loop

As we’ve mentioned before, you can use an If statement within a loop, performing actions only if certain criteria is met.

This code will hide all blank rows in a range:

Sub ForEachCell_inRange()

Dim cell As Range

For Each cell In Range("a1:a10")
    If cell.Value = "" Then _
       cell.EntireRow.Hidden = True
Next cell

End Sub

VBA Do While Loop

The VBA Do While and Do Until (see next section) are very similar. They will repeat a loop while (or until) a condition is met.

The Do While Loop will repeat a loop while a condition is met.

Here is the Do While Syntax:

Do While Condition
[Do Something]
Loop

Where:

• Condition – The condition to test
• [Do Something] – The code block to repeat

You can also set up a Do While loop with the Condition at the end of the loop:

Do 
[Do Something]
Loop While Condition

We will demo each one and show how they differ:

AutoMacro | Ultimate VBA Add-in | Click for Free Trial!

Do While

Here is the Do While loop example we demonstrated previously:

Sub DoWhileLoop()
    Dim n As Integer
    n = 1
    Do While n < 11
        MsgBox n
        n = n + 1
    Loop
End Sub

Loop While

Now let’s run the same procedure, except we will move the condition to the end of the loop:

Sub DoLoopWhile()
    Dim n As Integer
    n = 1
    Do
        MsgBox n
        n = n + 1
    Loop While n < 11
End Sub

VBA Do Until Loop

Do Until Loops will repeat a loop until a certain condition is met. The syntax is essentially the same as the Do While loops:

Do Until Condition
[Do Something]
Loop

and similarly the condition can go at the start or the end of the loop:

Do 
[Do Something]
Loop Until Condition

Do Until

This do Until loop will count to 10, like our previous examples

Sub DoUntilLoop()
    Dim n As Integer
    n = 1
    Do Until n > 10
        MsgBox n
        n = n + 1
    Loop
End Sub

AutoMacro | Ultimate VBA Add-in | Click for Free Trial!

Loop Until

This Loop Until loop will count to 10:

Sub DoLoopUntil()
    Dim n As Integer
    n = 1
    Do
        MsgBox n
        n = n + 1
    Loop Until n > 10
End Sub

Exit Do Loop

Similar to using Exit For to exit a For Loop, you use the Exit Do command to exit a Do Loop immediately

Exit Do

Here is an example of Exit Do:

Sub ExitDo_Loop()

Dim i As Integer
i = 1 

Do Until i > 1000
    If Range("A" & i).Value = "error" Then
        Range("A" & i).Select
        MsgBox "Error Found"
        Exit Do
    End If
    i = i + 1
Loop

End Sub

End or Break Loop

As we mentioned above, you can use the Exit For or Exit Do to exit loops:

Exit For

Exit Do

However, these commands must be added to your code before you run your loop.

If you are trying to “break” a loop that’s currently running, you can try pressing ESC or CTRL + Pause Break on the keyboard. However, this may not work.  If it doesn’t work, you’ll need to wait for your loop to end or, in the case of an endless loop, use CTRL + ALT + Delete to force close Excel.

This is why I try to avoid Do loops, it’s easier to accidentally create an endless loop forcing you to restart Excel, potentially losing your work.

Loop Through Rows

This will loop through all the rows in a column:

Public Sub LoopThroughRows()
 
Dim cell As Range
 
For Each cell In Range("A:A")
    If cell.value <> "" Then MsgBox cell.address & ": " & cell.Value
Next cell
 
End Sub

Loop Through Columns

This will loop through all columns in a row:

Public Sub LoopThroughColumns()

Dim cell As Range

For Each cell In Range("1:1")
    If cell.Value <> "" Then MsgBox cell.Address & ": " & cell.Value
Next cell

End Sub

Loop Through Files in a Folder

This code will loop through all files in a folder, creating a list:

Sub LoopThroughFiles ()

Dim oFSO As Object
Dim oFolder As Object
Dim oFile As Object
Dim i As Integer

Set oFSO = CreateObject("Scripting.FileSystemObject")

Set oFolder = oFSO.GetFolder("C:Demo)

i = 2

For Each oFile In oFolder.Files
    Range("A" & i).value = oFile.Name
    i = i + 1
Next oFile

End Sub

Loop Through Array

This code will loop through the array ‘arrList’:

For i = LBound(arrList) To UBound(arrList)
    MsgBox arrList(i)
Next i

The LBound function gets the “lower bound” of the array and UBound gets the “upper bound”.

Loops in Access VBA

Most of the examples above will also work in Access VBA. However, in Access, we loop through the Recordset Object rather than the Range Object.

Sub LoopThroughRecords()
   On Error Resume Next
   Dim dbs As Database
   Dim rst As Recordset
   Set dbs = CurrentDb
   Set rst = dbs.OpenRecordset("tblClients", dbOpenDynaset)
   With rst
      .MoveLast
      .MoveFirst
      Do Until .EOF = True
         MsgBox (rst.Fields("ClientName"))
        .MoveNext
     Loop
   End With
   rst.Close
   Set rst = Nothing
   Set dbs = Nothing
End Sub

Loops in VBA

Loops are an essential part of any programming language because they help with the repeated running of any code snippet. Just like any other language, VBA offers the following loops to enable efficient programming:

1. Do until
2. Do while
3. For
4. Foreach

In this article we will dive dep into the “for” loop which iterates only for “x” number of times where “x” is a known value before the loop’s runtime.

“X” can also be a predictable number at runtime, for example when you determine the Lbound and Ubound values of arrays.

The For Loop in VBA

In VBA, “for loop” is easy to use. It follows a simple and understandable syntax.

Syntax:

For <counter> = <start> to <end> [ <step value> ]

[ <code block to execute> ]

Next [ <counter> ]

where

<counter> is the iterator variable which keeps incrementing by the <step value> after every iteration. 

<step value> is optional. If this value is not provided, the default incremental value is “1.”

<Code block to execute> is also optional. It is the snippet of code to be executed during every iteration.

The “Next” statement marks the end of the “for” loop. It indicates to move to the next iteration of this loop with the incremented counter value.

Simple Examples of a For Loop

Print a Mathematical Table for a Number

Sub forloop_demo()
    ' declare all the required variables
    Dim counter, input_number As Integer
    
    ' Receive input from user
    input_number = InputBox(" Which tables do you want to print ? ")
    
    ' Print the mathematical table of the input number upto 12 count
    For counter = 1 To 12
        Debug.Print (counter & " X " & input_number & " = " & counter * input_number)
    Next
            
End Sub

This program receives a number as an input from the user. Then, using a “for” loop, it is multiplied with each number from 1 to 12 to print a “times table” table of that input number.

A sample output of this program if “3” is input by the user is seen in the image below.

Program to Print Contents of an Array

This program defines an array with its size. All elements of the array are assigned values one by one. Next they are printed as we iterate through a loop. It is noteworthy to say that the iterator variable (i) of the “for” loop is also used as the array index inside the loop (this is not mandatory but makes it easy to read/understand/maintain).

Sub array_cars()

'declaring variable while defining its size
Dim arr_my_cars1(5) As Variant

'initialize array elements for one array
 arr_my_cars1(0) = "Benz"
 arr_my_cars1(1) = "Maruthi"
 arr_my_cars1(2) = "Hyundai"
 arr_my_cars1(3) = "Ford"
 arr_my_cars1(4) = "Nissan"

'print all elements of the array
For i = LBound(arr_my_cars1) To UBound(arr_my_cars1)
    Debug.Print arr_my_cars1(i)
Next

End Sub

Output of the Program:

Benz

Maruthi

Hyundai

Ford

Nissan

Program to Write and Read Array Contents

This program slightly varies from the one above. Here you will create an array and iterate through it using its indices. 

Values are given to each array item using a “for” loop initially. (This was not the case in the previous program.)

Then, all the data stored in each element of the same array are read/printed back using another “for” loop.

Two loops are used here one below the other:

1. One to write data to array
2. Another one to read data from the same array.

Sub array_check_demo1()

' Declaration of array variable
Dim arr1(11)

' Assign values to array elements
For i = LBound(arr1) To UBound(arr1)
    'Allocate data for each array item through a loop
    arr1(i) = Cells(i + 2, 1).Value
Next

' Print values of the array
For i = LBound(arr1) To UBound(arr1)
    'Read data of each array item through a loop
    Debug.Print arr1(i)
Next
End Sub

Input is taken from the table below:

Principal amount	No of yrs	Age of customer
10000	5	67
340600	6	45
457800	8	34
23400	3	54
12000	4	23
23545	4	56
345243	2	55
34543	3	24
23223	2	19
3656	1	65

Program That Uses the [step] Value

Check out this program and try to find out why the numbers are not continuous in the output:

Sub step_demo()
' declare a counter
Dim p As Integer

'loop through 10 numbers and print them
For p = 1 To 10 step 3
	Debug.Print p
Next 
End Sub

Output of the Program

Yes, you might have found that the iterator variable increments by “3” instead of “1” in every iteration. Hence, the numbers printed are skip counted by “3.”

Try the same with different values in the place of [step] to understand it better if you are still confused.

The Nested “For” Loop

A loop within a loop is called a nested loop. 

Structure

Let me explain this structure with colors:

1. The for loop structure in yellow color is the outermost loop. 
2. The for loop structure/block in green color is the inner loop for the outermost (yellow color) loop. But it also acts as the outer loop for the “for loop” structure in turquoise color.
3. The for loop structure in turquoise color is the innermost loop. 

In this way , we can have any number of nested loops. 

But there are ample chances for you to get confused when you see your own code after several days. You will wonder inside which loop is a specific line and what role it plays in the whole code.

To avoid this, follow the tips below while you code your logic:

1. Maintain the alignment in your code with proper tab spaces as shown in the structure above. This can help you find the block of code/loop in which your statement is. 

If possible, use the iterator variable next to the “next” keyword. It can help you indicate which “next” statement  marks the closure of which loop. This is also marked in the colored structure for reference.

A Few Examples of Nested For Loops

Program to Format Cells with a Specific Word

This program iterates through all the cells (every column of every row in this case). If the cell content has a word “India,” then the specified formatting is applied to it.

Sub format_cell_with()
For i = 1 To 15
    For j = 1 To 5
    cellcontent = Cells(i, j).Value
    If InStr(cellcontent, "India") > 0 Then
        With Cells(i, j).Interior
        .Pattern = xlSolid
        .PatternColorIndex = xlAutomatic
        .ThemeColor = xlThemeColorAccent2
        .TintAndShade = 0.399975585192419
        .PatternTintAndShade = 0
        End With
    End If
    Next

Program with 2D Array and “NESTED FOR” Loop

This program declares a two dimensional array and initializes data in all its elements.

The first dimension holds the students’ names, and the second dimension holds the “exam results” of the students in the first dimension. These are written back to an Excel sheet. 

Warning: As the code does not select any sheet in specific, please ensure that you keep a blank Excel sheet selected. This can prevent any damage to your existing data.

In case you wish to learn more about multidimensional arrays, please check out this article.

Sub Nested_for_demo2()

'declaring and defining size of an array
'3 means 4 rows starting from 0 to 3 and 1 means 2 columns starting from 0 to 1
Dim arr_stu(1 To 5, 1 To 2) As Variant

'initialize array elements

 arr_stu(1, 1) = "Dave"
 arr_stu(1, 2) = "Fail"
 arr_stu(2, 1) = "Trumpo"
 arr_stu(2, 2) = "Pass"
 arr_stu(3, 1) = "Vincent"
 arr_stu(3, 2) = "Pass"
 arr_stu(4, 1) = "Rose Mary"
 arr_stu(4, 2) = "Pass"
 arr_stu(5, 1) = "Eliza"
 arr_stu(5, 2) = "Fail"
 
' print all elements to the open excel sheet.
For i = 1 To 5
    For j = 1 To 2
        Cells(i, j) = arr_stu(i, j)
    Next j
Next

End Sub

Output of the Program on the Active Excel Sheet: Here 

1. The rows indicate the “i” value of the array (first dimension) and the iterator variable of the outer “for” loop.
2. The columns indicate the  “j”  value of the array (Col A – first dimension , Col B – second dimension)  and the iterator variable of the inner “for” loop.

The “Continue” Statement in Visual Basic: Skip a Part of an Iteration

When you encounter a situation where you wish to skip running the rest of the code inside the loop for a specific iteration based on a condition, the “continue” statement will come to your rescue in Visual Basic Programming.

Continue

Syntax:

Continue { Do | For | While }

Where  { Do | For | While } are the respective loops in which it has to be used.

A Simple Example

Sub continue_demo()
' declare a counter
Dim i As Integer

'loop through 10 numbers and print them
For i = 1 To 10
    ' we will skip printing "4"
    If i = 4 Then
        Continue For
    End
    Debug.Print i
Next
End Sub

Your output will not have “4” in this case. As the condition is met in the 4^th iteration, the continue statement is hit and the rest of the code is skipped for that iteration. The control then moves to the “next” statement of the loop (inner loop in case of nested loops).  

Note: The Next statement is the closure of a loop, as you may be aware.

Continue Statement is Not Available in VBA

VBA does not offer the “continue statement” because well-built logic in a loop can help us avoid using a “continue” statement. For example, rearranging statement blocks like nested loops and if conditions can help avoid the use of “continue” statements. 

An Alternative to the Continue Statement

In unavoidable situations, the Goto statement can be used. 

This article can provide you with more insights on how to properly use the “Goto” statement in VBA.

Conclusion

In my experience, I would say that the “for” loop is my favorite compared to the “do while “/“Do until”/“ For each” loops. The reason is the comfort of defining it completely in one line. Even during run-time, you can find how many iterations are completed and how many are yet to come.

I have also been able to use this loop in situations where I do not know the number of iterations. I manage it using conditions inside the loop. It also comes handy when I want to wait for a page load during automation. Once you start using this loop, you will even start playing around nested “for loops” with much more confidence and fewer of mistakes. 

So, what are you waiting for ? Why not give it a try? 😊
