Take a look and see if you can spot them! Concatenating strings and numbers to represent cells is the key component of automating Excel.Īlmost every VBA article I write has some element of string concatenation. This is where the value of concatenation becomes evident. This combines the variables in such a way that it checks all the values in cells A1, A2, …, A100. Notice how I’m concatenating the string "A" with the integer i. Sub VBA_Loop_Through_Rows () dim i as Integer For i = 1 To 100 If Range ( "A" & i ) = "Waldo" Then 'you're concatenating MsgBox "You found Waldo!" End If Next i End Sub While it technically works when you have all strings, it won’t work the way you want it to when you trying combining strings and numbers. You must have a space before and after your ampersand to concatenate strings!Īnother mistake I see people make is trying to combine strings with the + symbol. This is by far the biggest mistake I see when people are trying to concatenate strings. Your line of code will turn red and you’ll get an error, like this: Let’s go up to my first example and try to remove the space between str1 and &. This is a very old feature of VBA that still exists for backward compatibility. When a variable is immediately followed by an ampersand (with no space), it tells VBA you are trying to declare the variable as a Long data type. This is extremely important because the ampersand has more than one meaning in VBA. Notice in all my examples there’s a space between the variable and the & operator. I know it’s tough, but it’s just one of those little things you have to memorize if you want to show quotation marks in your concatenated strings. Sub VBA_quotation_marks () strSound = "oink" MyString = "My pig goes " & " "" " & strSound & " "" " MsgBox MyString End Sub This article will be the first time I’ve actually explained what the ampersand operator is and why concatenation is so valuable to understand.įor more tips and tricks for handling strings, check out my Working with Strings series. If you’re familiar with my VBA tutorials, you no doubt have seen me use “&” to concatenate strings. Just like most other VBA tasks, there are many different ways to combine VBA strings, but the & operator is the best way. How you concatenate strings varies by programming language, but in VBA you simply add an ampersand between your strings to combine them into one string. When you concatenate strings, you are joining them together into one string. The word “concatenate” is used in almost all programming languages. “Concatenate” is just a fancy way of saying “combine” or “join.” This isn’t just a VBA thing. In VBA, you concatenate strings into a single string using the &, or ampersand, operator. ![]()
