Excel VBA ASC Function to get ASCII value of text

This page explains how to use Excel VBA ASCFunction to get ASCII value of a text, and how to check if a text contains an alphabet, number or symbol

What is Excel VBA ASC Function?

Excel VBA ASC Function returns the ASCII value of the first character in a text. ASCII (American Standard Code for Information Interchange) uses 8-bit code units, an old encoding system which stores mainly numbers, lowercase letters a to z, uppercase letters A to Z, basic punctuation symbols, control codes. Many old systems still use this encoding system. 8 bit means the computer memory uses “8” digits with 1 and 0 combination (binary) to represent a character, 8 bits memory is equal to 1 byte.

Refer to the below table, Excel ASC Function will convert the “Char” value to “Dec” value.

Why do you need Excel VBA ASC Function?

The main use of Excel Code Function is to convert alphabet into number. For example, you may want to know if a string contains A to Z, you can simply check if ASCII code is between 65 to 90, same for symbols.

Another use is to check unknown text. Some text looks like a space but underneath it may be something else, which is caused by conversion of other database type to Excel. After checking the ASCII code of that string, you can use Replace function to get rid of it.

Syntax of Excel VBA ASC Function

ASC(text)

Text The text which you want to convert into ASCII code

Note that ASC Function only returns the ASCII code of the first character in the text.

In Excel worksheet, ASC Function is called Code.

Example of Excel ASC Function

VBA Code	Result	Explanation
ASC(“A”)	65
ASC(“Z”)	90
ASC(UCASE(Range(“A1”).Value))>=65 AND ASC(UCASE(Range(“A1”).Value))<=90)	TRUE (assume A1 contains text “B”)	Check if the first text in Cell A1 is an alphabet

Loop through each character in a text to see if the any character contains an alphabet, disregard case sensitivity.

Public Function wCheckAlphabet(var)
    For i = 1 To Len(var)
        If Asc(Mid(UCase(var), i, 1)) >= 65 And Asc(Mid(UCase(var), i, 1)) <= 90 Then
            wCheckAlphabet = True
            Exit Function
        Else
            wCheckAlphabet = False
        End If
    Next i
End Function
