Sometimes you'll find yourself working with dates in an Excel spreadsheet that have been pasted or imported into Excel from another datasource.

This lesson looks at several ways you can convert a date which Excel is treating as text into a proper date value in Excel.

This lesson explains how to use Excel's logical operators and logical functions (AND, OR, NOT). These boolean operators can be used in a number of ways, either on their own, or to complement other Excel functions. In many cases, you can even use one of these functions instead of a more complicated function. For example, it is often easy to rewrite an IF statement using either AND or OR. This lesson includes examples of how to do this.
