VBA Automation for Excel 2019 Cookbook

By: Mike Van Niekerk

Overview of this book

Visual Basic for Applications (VBA) is a programming language developed by Microsoft to automate tasks in MS Office applications. This book will help you to focus on the essential aspects of your role by automating mundane tasks in Excel and other Office applications. With comprehensive coverage of VBA delivered in the form of practice problems and bite-sized recipes, this book will help you to hit the ground running. Unlike most books that assume prior programming experience, this book starts with the fundamentals and gradually progresses to solving bigger problems. You’ll start by becoming familiar with VBA so that you can start recording macros right away. With this foundation in place, you’ll advance to using the full capabilities of the language as you apply loops, functions, and custom dialog boxes to design your own automation programs. You'll also get to grips with embedded macros and other advanced tools to enhance productivity and explore topics relating to app performance and security. Throughout this VBA book, you’ll cover multiple practice projects in Excel, Word, and PowerPoint while exploring tips and best practices to hone your skills. By the end of this book, you’ll have developed the skills you need to use VBA to create your own programs that control MS Office applications.

Using loops

In this final recipe of this chapter, we will show you how to use loops.

Loops are used to automatically repeat a set of statements until a condition is met. There are different types of loops that can be used in VBA:

  • The Do loop
  • The Do-Until loop
  • The For Next loop

    For and For Each loops can both be used to iterate through collections and arrays. Only the For loop can be used to iterate through a range of specified values, for example, 1 to 10. Only the For loop can be used to replace items of an iterated collection or array.

  • Looping through a collection of objects

Getting ready

With ProgramFlow.xlsm still open on Sheet1, press Alt + F11 to switch to the VBA Editor With that open, insert a new module.

How to do it…

The first loop under discussion is the Do loop:

  1. Type the following code into the LoopSample Sub procedure:
    Sub LoopSample()
        Range("A1").Select
        Do
