One of the many features of Excel is being nosy. That's right, you can quickly calculate a persons age as long as you have their birth date.

Excel provides built-in tools to help you to find discrepancies like Filters, Conditional Formatting, advanced functions (If and IS, VLookUp, etc.), and Add-ins.

Filters are great tools, but you can't remove specific items from the results. When you need to do this, try Find All in Excel instead.
