Determining the Data Type of a Cell
In some situations you may need to determine the type of data in a cell. Excel provides a number of built-in functions that can help. These include ISTEXT, ISLOGICAL, and ISERROR. In addition, VBA includes functions such as IsEmpty, IsDate, and IsNumeric.
The CellType function (VBA code is listed below) accepts a range argument and returns a string that describes the data type of the upper left cell in the range. The function returns one of the following strings: Blank, Text, Logical, Error, Date, Time, or Value.
The CellType function
Function CellType(c)
' Returns the cell type of the upper left
' cell in a range
Application.Volatile
Set c = c.Range("A1")
Select Case True
Case IsEmpty(c): CellType = "Blank"
Case Application.IsText(c): CellType = "Text"
Case Application.IsLogical(c): CellType = "Logical"
Case Application.IsErr(c): CellType = "Error"
Case IsDate(c): CellType = "Date"
Case InStr(1, c.Text, ":") <> 0: CellType = "Time"
Case IsNumeric(c): CellType = "Value"
End Select
End Function
Using the CellType function
To use this function in a worskheet, just copy the code and paste it to a module. Then, you can enter a formula such as:
=CellType(A1)
