There are many times when writing macros that you need to convert strings to numbers. You can do this with the Val() function. This function returns the value of a string, up to the first nonnumeric character. The following are examples:

This article is written for users of the following Microsoft Excel versions: 2007, 2010, 2013, and 2016. If you are using an earlier version (Excel 2003 or earlier), this tip may not work for you. For a version of this tip written specifically for earlier versions of Excel, click here: 
A = Val(MyString)
B = Val("-12345.67")
C = Val("9876")
D = Val(" 4 5 2 1")
The first line converts MyString into a value, placing it in A. The second line results in B being set to —12345.67. The third places the value 9876 into C, and the final line sets D equal to 4521. Notice that spaces are ignored in the conversion; this is why the final line works the way it does. You should also note that trying to use formatted numbers in a conversion will confuse the Val() function. Thus, Val("1,234") would not return a value of 1234 (as one might hope), but a value of 1. The conversion stops at the first nonnumeric character, in this case the comma.

I thought this tip was going to be along the lines of when you import data and the values arrive as text. The operations above are doable but I usually drop a numeric "1" into a blank cell, copy it and paste special-multiply the text values. This is an old trick but Excel now flags anomalous looking number values that are actually text and gives you that adjoining drop-down box to convert text to numbers. Even if the data column contains some text and some numeric values, the Excel-provided conversion still works.
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
