Chapter 27. Manipulating Files with VBA

In This Chapter

In this chapter, I describe how to use Visual Basic for Applications (VBA) to perform common (and not so common) file operations and work directly with text files.

  • A basic overview of VBA text file manipulation features

  • Performing common file operations

  • Various ways to open a text file

  • Displaying extended file information, such as details for media files

  • Examples of reading and writing a text file with VBA

  • Sample code for exporting a range to HTML and XML format

  • Zipping and unzipping files

Excel, of course, can import and export several types of text files. In many cases, however, Excel’s built-in text file handling isn’t sufficient. For example, you might want to export a range of cells to a simple HyperText Markup Language (HTML) file.

Performing Common File Operations

Excel provides two ways to perform common file operations:

  • Use traditional VBA statements and functions. This method works for all versions of Excel.

  • Use the FileSystemObject object, which uses the Microsoft Scripting Library. This method works for Excel 2000 and later.
