VBA Type Mismatch Error – The Ultimate Guide

 

VBA Type Mismatch Explained

A VBA Type Mismatch Error occurs when you try to assign a value between two different variable types.

The error appears as “run-time error 13 – Type mismatch”.

VBA Type Mismatch Error 13

 

For example, if you try to place text in a Long integer variable or you try to place text in a Date variable.

Let’s look at a concrete example. Imagine we have a variable called Total which is a Long integer.

 

If we try to place text in the variable we will get the VBA Type mismatch error(i.e. VBA Error 13).

' https://excelmacromastery.com/
Sub TypeMismatchString()

    ' Declare a variable of type long integer
    Dim total As Long
    
    ' Assigning a string will cause a type mismatch error
    total = "John"
    
End Sub

 

Let’s look at another example. This time we have a variable ReportDate of type Date.

If we try to place a non-date in this variable we will get a VBA Type mismatch error

' https://excelmacromastery.com/
Sub TypeMismatchDate()

    ' Declare a variable of type Date
    Dim ReportDate As Date
    
    ' Assigning a number causes a type mismatch error
    ReportDate = "21-22"
    
End Sub

 

In general, VBA is very forgiving when you assign the wrong value type to a variable e.g.

Dim x As Long

' VBA will convert to integer 100
x = 99.66

' VBA will convert to integer 66
x = "66"

 

However, there are some conversions that VBA cannot do

Dim x As Long

' Type mismatch error
x = "66a"

 

A simple way to explain a VBA Type mismatch error, is that the items on either side of the equals evaluate to a different type.

When a Type mismatch error occurs it is often not as simple as these examples. For these more complex cases we can use the Debugging tools to help us resolve the error.

How to Locate the Type Mismatch Error

The most important thing to do when solving the Type Mismatch error is to, first of all, locate the line with the error and then locate the part of the line that is causing the error.

If your code has Error Handling then it may not be obvious which line has the error.

If the line of code is complex then it may not be obvious which part is causing the error.

The following video will show you how to find the exact piece of code that causes a VBA Error in under a minute:

 

The following sections show the different ways that the VBA Type Mismatch error can occur.

Assigning a string to a numeric

As we have seen, trying to place text in a numeric variable can lead to the VBA Type mismatch error.

Below are some examples that will cause the error

' https://excelmacromastery.com/
Sub TextErrors()

    ' Long is a long integer
    Dim l As Long
    l = "a"
    
    ' Double is a decimal number
    Dim d As Double
    d = "a"
    
    ' Currency is a 4 decimal place number
    Dim c As Currency
    c = "a"
    
    Dim d As Double
    ' Type mismatch if the cell contains text
    d = Range("A1").Value
    
End Sub

 

Invalid date

VBA is very flexible when it comes to assigning a date to a date variable. If you put the month in the wrong order or leave out the day, VBA will still do it’s best to accommodate you.

The following code examples show all the valid ways to assign a date followed by the cases that will cause a VBA Type mismatch error.

' https://excelmacromastery.com/
Sub DateMismatch()

    Dim curDate As Date
    
    ' VBA will do it's best for you
    ' - These are all valid
    curDate = "12/12/2016"
    curDate = "12-12-2016"
    curDate = #12/12/2016#
    curDate = "11/Aug/2016"
    curDate = "11/Augu/2016"
    curDate = "11/Augus/2016"
    curDate = "11/August/2016"
    curDate = "19/11/2016"
    curDate = "11/19/2016"
    curDate = "1/1"
    curDate = "1/2016"
   
    ' Type Mismatch
    curDate = "19/19/2016"
    curDate = "19/Au/2016"
    curDate = "19/Augusta/2016"
    curDate = "August"
    curDate = "Some Random Text"

End Sub

 

Cell Error

A subtle cause of the VBA Type Mismatch error is when you read from a cell that has an error e.g.

VBA Runtime Error

If you try to read from this cell you will get a type mismatch error

Dim sText As String

' Type Mismatch if the cell contains an error
sText = Sheet1.Range("A1").Value

To resolve this error you can check the cell using IsError as follows.

Dim sText As String
If IsError(Sheet1.Range("A1").Value) = False Then
    sText = Sheet1.Range("A1").Value
End If

However, checking all the cells for errors is not feasible and would make your code unwieldy. A better way is to check the sheet for errors first and if errors are found then inform the user.

You can use the following function to do this

Function CheckForErrors(rg As Range) As Long

    On Error Resume Next
    CheckForErrors = rg.SpecialCells(xlCellTypeFormulas, xlErrors).Count

End Function

The following is an example of using this code

' https://excelmacromastery.com/
Sub DoStuff()

    If CheckForErrors(Sheet1.Range("A1:Z1000")) > 0 Then
        MsgBox "There are errors on the worksheet. Please fix and run macro again."
        Exit Sub
    End If
    
    ' Continue here if no error

End Sub

 

Invalid Cell Data

As we saw, placing an incorrect value type in a variable causes the ‘VBA Type Mismatch’ error. A very common cause is when the value in a cell is not of the correct type.

A user could place text like ‘None’ in a number field not realizing that this will cause a Type mismatch error in the code.

VBA Error 13

If we read this data into a number variable then we will get a ‘VBA Type Mismatch’ error error.

Dim rg As Range
Set rg = Sheet1.Range("B2:B5")

Dim cell As Range, Amount As Long
For Each cell In rg
    ' Error when reaches cell with 'None' text
    Amount = cell.Value
Next rg

You can use the following function to check for non numeric cells before you use the data

Function CheckForTextCells(rg As Range) As Long

    ' Count numeric cells
    If rg.Count = rg.SpecialCells(xlCellTypeConstants, xlNumbers).Count Then
        CheckForTextCells = True
    End If
    
End Function

You can use it like this

' https://excelmacromastery.com/
Sub UseCells()

    If CheckForTextCells(Sheet1.Range("B2:B6").Value) = False Then
        MsgBox "One of the cells is not numeric. Please fix before running macro"
        Exit Sub
    End If
    
    ' Continue here if no error

End Sub

 

Module Name

If you use the Module name in your code this can cause the VBA Type mismatch to occur. However in this case the cause may not be obvious.

For example let’s say you have a Module called ‘Module1’. Running the following code would result in the VBA Type mismatch error.

' https://excelmacromastery.com/
Sub UseModuleName()
    
    ' Type Mismatch
    Debug.Print module1

End Sub

VBA Type Mismatch Module Name

 

Different Object Types

So far we have been looking mainly at variables. We normally refer to variables as basic data types.

They are used to store a single value in memory.

In VBA we also have objects which are more complex. Examples are the Workbook, Worksheet, Range and Chart objects.

If we are assigning one of these types we must ensure the item being assigned is the same kind of object. For Example

' https://excelmacromastery.com/
Sub UsingWorksheet()

    Dim wk As Worksheet
    
    ' Valid
    Set wk = ThisWorkbook.Worksheets(1)
    
    ' Type Mismatch error
    ' Left side is a worksheet - right side is a workbook
    Set wk = Workbooks(1)

End Sub

 

Sheets Collection

In VBA, the workbook object has two collections – Sheets and Worksheets. There is a very subtle difference

  1. Worksheets – the collection of worksheets in the Workbook
  2. Sheets – the collection of worksheets and chart sheets in the Workbook

A chart sheet is created when you move a chart to it’s own sheet by right-clicking on the chart and selecting Move.

If you read the Sheets collection using a Worksheet variable it will work fine if you don’t have a chart sheet in your workbook.

If you do have a chart sheet then you will get the VBA Type mismatch error.

In the following code, a Type mismatch error will appear on the Next sh line if the workbook contains a chart sheet.

' https://excelmacromastery.com/
Sub SheetsError()

    Dim sh As Worksheet
    
    For Each sh In ThisWorkbook.Sheets
        Debug.Print sh.Name
    Next sh

End Sub

 

Array and Range

You can assign a range to an array and vice versa. In fact this is a very fast way of reading through data.

' https://excelmacromastery.com/
Sub UseArray()

    Dim arr As Variant
    
    ' Assign the range to an array
    arr = Sheet1.Range("A1:B2").Value
    
    ' Print the value a row 1, column 1
    Debug.Print arr(1, 1)

End Sub

 

The problem occurs if your range has only one cell. In this case, VBA does not convert arr to an array.

If you try to use it as an array you will get the Type mismatch error

' https://excelmacromastery.com/
Sub UseArrayError()

    Dim arr As Variant
    
    ' Assign the range to an array
    arr = Sheet1.Range("A1").Value
    
    ' Type mismatch will occur here
    Debug.Print arr(1, 1)

End Sub

 

In this scenario, you can use the IsArray function to check if arr is an array

' https://excelmacromastery.com/
Sub UseArrayIf()

    Dim arr As Variant
    
    ' Assign the range to an array
    arr = Sheet1.Range("A1").Value
    
    ' Type mismatch will occur here
    If IsArray(arr) Then
        Debug.Print arr(1, 1)
    Else
        Debug.Print arr
    End If

End Sub

  1. I am getting a “Run-time error 13- Type Mismatch” in MS project. When I click debug I get “If version > 12 Then call AddPPMToolRibbon”. Need help please

  2. Hi Paul,
    I’m getting a mismatch error for a date. I have a table with lots of different ideas with about 5 possible dates (as the ideas go through stages) and first I’m trying to sort the data for easier reading and eventually equations. I have “Dim hopper as Date” and the row that is flagged/highlighted when the error message pops up is “hopper = ActiveCell.Offset(0,23).Value” . The quotation marks are not included in the code. The information grabbed before this date looks right and the column is the right column, but the cell is blank. Is the error because the date is blank? If so, how do I tell the computer to leave the value of hopper for that idea blank?

    Thank you!

    1. The date cannot be blank. Check if it the cell = “” and if it does then don’t assign the date.
