Lesson 23: Managing External Data

Managing external Data
One of the most versatile and useful benefits of Excel is its ability to import data from external
sources. In Lessons 26–30 you will see examples of sharing data back and forth with other
Microsoft Office applications from Excel.
Prior to Excel 97, the data that a person would be working with was entered into Excel
manually. An Excel workbook was essentially a self-contained object that produced and stored its
own data, having almost no contact with the outside world except for the person working in
the project.
Starting with Office 97, Microsoft has been devoted to providing more and better tools for
importing and exporting data to the Internet, database programs, and text-related software
applications. Excel leads the way in this effort among all Office applications. In this lesson,
you learn how to use VBA to share data between Excel and other external sources, including
Access, the Internet, and text files.

The Internet as we know it has only been around since the mid 1990s, not that long ago really,
but it’s hard to imagine what life would be like today without the World Wide Web. The
public’s desire is only increasing for access to the galaxy of information that is stored on the Web.
With each new release of its Office suite, Microsoft has improved the capacity of its
applications to interact with web-based information.
When you connect Excel to an external source such as the Internet, you add a
Q uer yTable to your worksheet. Objects that can connect to external data sources
include a cell range, an Excel table, a pivot table, a text file, and a Web query. In
this case, you are adding a QueryTable to a worksheet because you are querying
the Web for information that will be displayed on your worksheet.
