In Excel 2010: Data Validation in Depth, author Dennis Taylor shows how to use the data validation tools in Excel to control how users can input data into workbooks and ensure data is entered consistently and accurately. The course covers creating dropdown lists, preventing duplicate entries, and controlling the format of numeric data, dates and times, and text entered into worksheets. Exercise files are included with the course.
If you have access to the course files, you may want to store them in a convenient location--perhaps the Desktop--and open them as I am right now, and choosing, for example, chapter 3. All of the worksheets associated with chapter 3 are stored in this particular file right here. If you do not have these files available, feel free to use your own data as you work through the course.
