How to check or determine data type of cell?

In certain case, you may want to know the data type of the values in the cells, such as blank, error, date or something else. May be your first thought is the Type function in Excel, but this function just can check four types of the data which is not incomplete, so here, I can talk about another method to help you solve this task.

Check or determine the data type with User Defined Function

arrow blue right bubble Check or determine the data type with User Defined Function

In Excel, you can create User Defined Function to check the data type, please do with the following steps:

1. Hold down the Alt + F11 keys in Excel, and it opens the Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste the following macro in the Module Window.

VBA code: Check or determine the data type in Excel

Function CellType(pRange As Range)
Set pRange = pRange.Range("A1")
Select Case True
    Case VBA.IsEmpty(pRange): CellType = "Blank"
    Case Application.IsText(pRange): CellType = "Text"
    Case Application.IsLogical(pRange): CellType = "Logical"
    Case Application.IsErr(pRange): CellType = "Error"
    Case VBA.IsDate(pRange): CellType = "Date"
    Case VBA.InStr(1, pRange.Text, ":") <> 0: CellType = "Time"
    Case VBA.IsNumeric(pRange): CellType = "Value"
End Select
End Function

3. Then save and close this code, go back to the worksheet, and enter this formula =CellType (A1) into a blank cell besides your data range, see screenshot:


4. Then drag the fill handle over to the cells which you want to contain this formula, and all data types have been extracted from the cells, see screenshot:
