The macro recorder generates VBA code which you can read and edit, giving you a stepping-stone to learn how to code your own macros from scratch.įor more information, see the article “ How to Record a Macro”. The easiest way to get started with macros is to record them using the Macro Recorder built into Excel. With VBA, macros can be programmed to automate tasks like these, turning a series of manual operations into a single button click. Sometimes these are minor tasks like copy-pasting subsets of data to different sheets, and sometimes the tasks are more complex like uploading data to a website. Users of Microsoft Excel will often find themselves repeating the same series of tasks over and over again. VBA is used to write macros, which automate simple and complex tasks in Excel. The following is a series of frequently asked questions about VBA, with answers for both newcomers to Excel macros and seasoned programmers. When you run a macro it’s this code that Excel reads to replay your actions. VBA is human-readable (and editable) programming code that gets generated when you record a macro. If you’ve ever used macros in Excel, you’ve used Visual Basic for Applications (VBA).

The value of num1 is now 13, and the value of str1 is now "103". In both cases, the result is assigned to the first variable. The second part uses += with String variables to concatenate one value with another. The first part uses += with numeric variables to add one value to another. The following example uses the += operator to combine the value of one variable with another. For more information, see Operator Procedures. If your code uses += on a class or structure that overloads +, be sure you understand its redefined behavior. Overloading the + operator affects the behavior of the += operator. The + operator can be overloaded, which means that a class or structure can redefine its behavior when an operand has the type of that class or structure. For details on these conversions, see + Operator. If permissive semantics are allowed, the += operator implicitly performs a variety of string and numeric conversions identical to those performed by the + operator.

For more information on strict and permissive semantics, see Option Strict Statement. For more information on these conversions, see Widening and Narrowing Conversions. This assignment operator implicitly performs widening but not narrowing conversions if the compilation environment enforces strict semantics. Use the &= operator for concatenation to eliminate ambiguity and to provide self-documenting code.

When you use the += operator, you might not be able to determine whether addition or string concatenation will occur.
