How to allow only numbers to be input in text box?

Author Xiaoyang Last modified

In Excel, we can apply the Data Validation function to allow only numbers to be entered into cells, but, sometimes, I want only numbers to be typed into a textbox as well as in cells. How to accept only numbers in a textbox in Excel?

Divide a range of cells by a number with Paste Special function

The following VBA code can help you to enter numbers, period (.) and a negative sign only into a textbox, please do as this:

1. Create a textbox by clicking Developer > Insert > Text Box (ActiveX Control), and then draw a textbox as you need, see screenshot:

insert textbox from Developer tab

2. Then right click the textbox and select View Code from context menu to open the Microsoft Visual Basic for Applications window, and then replace the original code with the following VBA code into the blank module:

VBA code: Allow only numbers to be input into the textbox:

Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
    If KeyAscii > Asc("9") Or KeyAscii < Asc("0") Then
        If KeyAscii = Asc("-") Then
            If InStr(1, Me.TextBox1.Text, "-") > 0 Or _
               Me.TextBox1.SelStart > 0 Then KeyAscii = 0
        ElseIf KeyAscii = Asc(".") Then
            If InStr(1, Me.TextBox1.Text, ".") > 0 Then KeyAscii = 0
        Else
            KeyAscii = 0
        End If
    End If
End Sub

click View Code to insert vba code

3. Then save and close the code window, and exit the Design Mode, now, only numbers, period symbol and negative sign can be entered into the textbox, see screenshot:
