The AND function is another of Excel's Logical Functions. In general, a logical function only gives you a true or false answer. It evaluates the data in a spreadsheet cell to see if that data meets the specified criteria. If it does, the function returns a True response in the cell where the function is located. If not, a False statement is returned.

The AND function allows you to specify up to 255 criteria to be evaluated. All of these criteria would need to meet the specified criteria for the function to give you a True response.

As with the OR function, the AND function, by itself, has limited usefulness. When by combining it with another function, such as the IF function, the AND function can greatly increase the capabilities of your spreadsheet.

To find out how to use this function, read this short article on the Excel AND Function.

Nested IF Functions in Excel

Wednesday October 1, 2008
Believe it or not some people shy away from using the IF function because of its apparent complexity. In doing so, they are missing out on one of the most useful functions available in spreadsheet programs like Excel.

Using the IF function adds flexibility to a spreadsheet by introducing decision making. What the IF function does is test to see if a certain condition is true or false. If it is true, the function enters one result in a specific cell. If the condition is false, it enters a different result into that cell.

To further increase the flexibility of your spreadsheets, it is possible to Nest or place one IF function inside another.

The IF function works by testing to see if a certain condition is true. If it is, the function enters one result in a specific cell, if it is not; it enters a different result in that cell.

Excel 2007 QUOTIENT Function

Sunday September 21, 2008
The QUOTIENT function is another of Excel's functions that can be used to carry out mathematical operations in a spreadsheet.

In particular, the QUOTIENT function provides a way to divide numbers in a spreadsheet without having to create formulas all the time.

One characteristic of the QUOTIENT function, however, is that it discards any remainder and only shows the integer or whole number as the answer. The function, therefore, can't be used in place of all division operations.

Excel’s Format Painter

Tuesday September 16, 2008
One of the features I really like in Excel, and one that I use frequently is the format painter. My affection for this feature stems from how easy it is to use, and how quickly it allows you to add formatting options to a spreadsheet.

What format painter allows you to do is, with the single click of the icon, copy all the formatting options from one cell and paste them into another cell or cells in a spreadsheet. The cells don't even need to be adjacent to each other when you do this.

In versions of Excel 97 through to 2003, format painter can be found on the Standard toolbar. In Excel 2007, it is located on the Home tab of the ribbon menu. To find out how using this feature can simplify formatting a spreadsheet, read the article on Excel’s Format Painter.
