Microsoft Excel Tutorial: Excel Custom Number Formatting Zones Based on Conditions.

Welcome back to another episode of the MrExcel netcast! In this video, we're going to dive deeper into custom number formats and learn how to create our own zones for highlighting data in Excel. If you missed our previous video, we discussed the four default zones for positive, negative, zero, and text values. But what if you want to create your own zones based on specific criteria? Well, that's exactly what we're going to cover today.

Let's say you want to highlight all numbers above 90 as good and anything below 80 as bad. With custom number formatting, you can easily achieve this by defining your own zones using square brackets. For numbers greater than 90, we'll use the format [>90] in green with a star symbol and the number. Similarly, for numbers less than 80, we'll use the format [<80] in red with an exclamation mark and the number. And for any other numbers, we'll use the format [Blue] with just the number. Once you click OK, you'll see the high numbers highlighted in green, low numbers in red with exclamation points, and everything else in blue.

Now, this may seem like a primitive method compared to conditional formatting, but it's still a clever way to control the color and appearance of your data. Plus, the important thing to note is that the actual value of the cell remains unchanged. This means you can still use formulas to work with these numbers. So, whether you want to add them up or perform any other calculations, it's all possible with custom number formatting.
