There are times when it is helpful to know if a cell contains something—it doesn't really matter what it contains, just that it contains something. In these instances, there are two ways you can approach the problem.
The first solution is to simply use the LEN function to determine if there is a length to what is contained in a cell. For instance, let's say you wanted to check if there was a value in cell F1. You could use the following:
=IF(LEN(F1)>0,"Found something there","Nothing is there")
If there is nothing in cell F1, then the length will be equal to zero. If there is something in the cell, then the length will be greater than zero.
The second solution is a variation on the LEN approach. All you need to do is check to see if there is anything in the cell. This may sound odd, but it is easier when you see the formula. For example, the following will check to see if there is anything in cell B4:
=IF(B4<>"","Found something there","Nothing is there")
The test in this formula is True if there is anything in the cell. If the cell is empty, then the test fails.
Another solution you can use is the ISBLANK worksheet function. This function returns True if the target cell is blank, and False if it contains anything.
As an example, let's suppose you want to check if the user has entered something in cell D7. You can use the following to make the determination:
=IF(ISBLANK(D7),"Input values missing",D7)
In this case the cell containing this formula would contain the same value as in D7, provided something was there. If there is nothing in D7, then the cell contains the text "Input values missing."

I had a similar problem when I was entering data. I had opted to hide zeros, so I needed to show the cells with zero but not see the value. I did this with a conditional format that used the formula like =NOT(ISBLANK(A1)) that applied a soft pastel colour to the fill when true. Note the lack of $ signs in the formula. This seems to work fine with text, numbers, errors and formulas.

Further to Mike's comment
ISBLANK returns false if aef contains a formula
e.g. if(a1=0,"","Value")

Very useful remark! Thanks!

These 3 methods are not exactly equal!
If the target cell contains just a single quote, the ISBLANK() method will detect it, but the LEN() method and the <>"" method will find nothing. Might be relevant if searching for the last used cell, as Find/Replace doesn't find it either.

Thank you for providing the variety of methods to detect cell content. I usually just jump to the Boolean option (<>), but it's a greater reminder to see the 2 functions, LEN and ISBLANK, as options. You're providing a great service to us in the Excel community! Cheers
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
