VBA String to Date

Excel VBA String to Date

In Vba there is a method through which we can convert a given string to a date, and the method is known as CDATE function in vba, this is an inbuilt function in VBA and the parts required for this function is to first convert the string to a number and then we convert the given number to a date. The result format depends on system date format only.

One of the common problems we all face with excel is “Date & Time” and are often stored as text values and go unnoticed initially. But when they are required to use that time we will get to know that those values are stored as text and don’t know how to deal with them at all. “Date & Time” are two combined things in one element but once those values are stored as text values it is pain to work with.

How to Convert String Values to Date?

Example #1

Once the VBA variable is declared and assigned as String, anything assigned to that variable will be treated as string only. For an example look at the below code.

Code:

Sub String_To_Date()

  Dim k As String
  k = "10-21"
  MsgBox k

End Sub

In the above code variable “k” defined as “String” data type and for this variable we have assigned the value as “10-21”.

Ok, let’s run the code and see what we get in the message box in VBA.

We got the value as 10-21 only, but usually, these values are a date, not string values. So even though the data type assigned is “String” we can still convert to date by using data type conversion function “CDATE”.

Code:

Sub String_To_Date()

  Dim k As String
  k = "10-21"
  MsgBox CDate(k)

End Sub

In the above, before we show the result of the variable “k” in the message box we have assigned the CDATE function. A small adjustment is made, let’s see how big an impact it makes.

Now we would see the result as “Date” no longer as “String” value.

Example #2

Now, look at the below code for an example.

Code:

Sub String_To_Date()

  Dim k As String
  k = 43599
  MsgBox k

End Sub

At this point in time above code would show the result as “43599” as we assigned above.

But once we use the CDATE function it will convert to date value.

Code:

Sub String_To_Date()

  Dim k As String
  k = 43599
  MsgBox CDate(k)

End Sub

The result after applying the CDATE function is as follows.

Since excel stored the date as serial numbers our assigned serial number 43599 is equal to the date 05/14/2019 when the date format is applied.

We can also apply the format to the date as “DD-MMM-YYYY” to read the date accurately.

Code:

Sub String_To_Date1()

  Dim k As String
  Dim DateValue As Date

  k = 43599
  DateValue = CDate(k)
  MsgBox Format(DateValue, "DD-MMM-YYYY")

End Sub

In the above, I have declared one extra variable to store the result. For this variable, I have applied the CDATE conversion function.

Next, I have used FORMAT function to apply the format of the “DD-MMM-YYYY” format and the result will be as shown below.

With this, we can clearly read the daypart and month part. It also depends on your system date format, since my system date format was “MM-DD-YYYY” it was showing like that but that should not be a hindrance to format.

Example #3

Now we will see actually how dates are formatted as text values in worksheet cells. Below is the image of the dates stored as text in a worksheet.

In column A from A2 to A12 we have date looking values but when we look at the format tab it shows “Text” format. Now we need to convert these values from text to date.

Below is the code I have written to convert the text-formatted date values to actual dates.

Code:

Sub String_To_Date2()

Dim k As Long

 'Data is in more than one cell, so need to loop through each cell
 'Open For Loop

For k = 2 To 12
 'Data starts from 2nd row and ends at 12th row, so 2 to 12
   Cells(k, 2).Value = CDate(Cells(k, 1).Value)
Next k

End Sub

If you run the code it will give us the below result.

Things to Remember

• CDATE is a data type conversion function but can be used to convert VBA string stored date to actual date values.
• The result of the CDATE function format depends on system date format only.
• Dates are stored as serial numbers in excel, so formatting is required to show them as dates.
