If error null excel

If cell is not blank

Summary

To test if a cell is not blank (i.e. has content), you can use a formula based on the IF function. In the example shown, the formula in cell E5 is:

As the formula is copied down it returns «Done» when a cell in column D is not blank and an empty string («») if the cell is blank.

Generic formula

Explanation

In this example, the goal is to create a formula that will return «Done» in column E when a cell in column D contains a value. In other words, if the cell in column D is «not blank», then the formula should return «Done». In the worksheet shown, column D is is used to record the date a task was completed. Therefore, if the column contains a date (i.e. is not blank), we can assume the task is complete. This problem can be solved with the IF function alone or with the IF function and the ISBLANK function. It can also be solved with the LEN function. All three approaches are explained below.

IF function

The IF function runs a logical test and returns one value for a TRUE result, and another value for a FALSE result. You can use IF to test for a blank cell like this:

In the first example, we test if A1 is empty with =»». In the second example, the <> symbol is a logical operator that means «not equal to», so the expression A1<>«» means A1 is «not empty». In the worksheet shown, we use the second idea in cell E5 like this:

If D5 is «not empty», the result is «Done». If D5 is empty, IF returns an empty string («») which displays as nothing. As the formula is copied down, it returns «Done» only when a cell in column D contains a value. To display both «Done» and «Not done», you can adjust the formula like this:

ISBLANK function

Another way to solve this problem is with the ISBLANK function. The ISBLANK function returns TRUE when a cell is empty and FALSE if not. To use ISBLANK directly, you can rewrite the formula like this:

Notice the TRUE and FALSE results have been swapped. The logic now is if cell D5 is blank. To maintain the original logic, you can nest ISBLANK inside the NOT function like this:

The NOT function simply reverses the result returned by ISBLANK.

LEN function

One problem with testing for blank cells in Excel is that ISBLANK(A1) or A1=»» will both return FALSE if A1 contains a formula that returns an empty string. In other words, if a formula returns an empty string in a cell, Excel interprets the cell as «not empty». To work around this problem, you can use the LEN function to test for characters in a cell like this:

This is a much more literal formula. We are not asking Excel if A1 is blank, we are literally counting the characters in A1. The LEN function will return a positive number only when a cell contains actual characters.

Null in Excel

Null is an error that occurs in Excel when the two or more cell references provided in a formula are incorrect, or the position they have been placed in is erroneous. For example, suppose we use space in formulas between two cell references; we will encounter a null error. In that case, there are two reasons to meet this error, one if we used an incorrect range reference and another when we use the intersect operator, which is the space character.

Null in Excel

NULL is nothing but nothing or blank in Excel. Usually, when working in Excel, we encounter many NULL or blank cells. We can use the formula and find out whether the particular cell is blank (NULL) or not.

We have several ways of finding the NULL cells in Excel. Today’s article will take a tour of dealing with NULL values in Excel.

How do you find which cell is blank or null? Yes, we must look at the particular cell and decide. Let us discover many methods of finding the null cells in Excel.

ISBLANK Function to Find NULL Value in Excel

The syntax is straightforward. Value is nothing but the cell reference; we are testing whether it is blank or not.

Note: ISBLANK will treat the single space as one character; if the cell has only space value, it will be recognized as a non-blank or non-null cell.

#1 – How to Find NULL Cells in Excel?

Assume we have the values below in the Excel file and want to test all the null cells in the range.

Let us open the ISBLANK formula in cell B2 cell.

Select cell A2 as the argument. Since there is only one argument, close the bracket.

We got the result as given below:

Then, drag and drop the formula to other remaining cells.

We got the results. But look at cell B7. Even though there is still no value in cell A7, the formula returned the result as a FALSE, non-null cell.

It counts the no. of characters and gives the result.

The LEN function returned the no. of character in the A7 cell as 1. So, there should be a character in it.

Let us edit the cell now. So, we found the space character here. Let us remove the space character to make the formula show accurate results.

We have removed the space character, and the ISBLANK formula returned the result as TRUE. That is because even the LEN function says there are zero characters in cell A7.

#2 – Shortcut Way of Finding NULL Cells in Excel

We have seen the traditional formula way to find the null cells. Without using the ISBLANK function, we can find the null cells.

Let us open the formula with an equal sign (=).

After the equal sign, select cell A2 as the reference.

Now open one more equal sign after the cell reference.

Now mention open double-quotes and close double-quotes. (“”)

The sign double quotes (“”) says the selected cell is NULL or not. If the selected cell is NULL, we will get TRUE. Else, we will get FALSE.

Drag the formula to the remaining cells.

We can see that in cell B7, we got the result as “TRUE.” So it means it is a null cell.

#3 – How to Fill Our Values to NULL Cells in Excel?

We have seen how to find the NULL cells in the Excel sheet. In our formula, we could only get TRUE or FALSE. But we can also receive our values for the NULL cells.

Consider the below data for an example.

Step 1: Open the IF condition first.

Step 2: Here, we need to do a logical test. We need to test whether the cell is NULL or not. So apply A2=”.”

Step 3: If the logical test is TRUE (TRUE means cell is NULL), we need the result as “No Values Found.”

Step 4: If the logical test is FALSE (which means the cell contains values), then we need the same cell value.

We got the result as the same cell value.

Step 5: Drag the formula to the remaining cells.

So, we have got our value of No Values Found for all the NULL cells.

Things to Remember

• Even space will be considered a character and treated as a non-empty cell.
• Instead of ISBLANK, we can also use double quotes (“ ”) to test the NULL cells.
• If the cell seems blank and the formula shows it as a non-null cell, then you need to test the number of characters using the LEN function.

What is Null Error in Excel?

Null is an error value in a cell when Excel cannot properly evaluate a worksheet formula or function. This error is shown when you use an incorrect range operator in a formula or when you use an intersection operator. The error value itself plus the Error Option Button, displayed in the error formula, helps identify the problem by showing a small green triangle containing error values. The small green triangle indicates one of the cell contents is violating one of Excel’s errors checking rules.

Excel functions, formula, charts, formatting creating excel dashboard & others

So here below, we will show you how it looks like.

As shown in the above screenshot, the green triangle and a yellow diamond-shaped button which is next to that cell marked with Red Arrows and when you click that Yellow Diamond shaped icon in the cell will show you the Excel’s error options button, which contains the options in the drop-down list to correct the perceived error.

Examples of NULL in Excel

Excel display some of the #Null! Errors which are very common. We will show you the list of those common error values along with some examples.

Example #1

As shown below, we have the employees name in Column A and Productive Hours in Column B, so if we want to get the Total Productive hours of the below employees, we will Sum the hours from Column B2 to B4 but we have to input the Formula (=B2+B3 B4).

We have given space instead of the plus sign(+), so we got the #NULL! Error in Column B5.

Now to rectify the error, we can click the Yellow Diamond Icon, and we will show that we need to input the correct formula in the formula bar, which is (=B2+B3+B4), which will give us the Total Productive Hours and rectify the #NULL! Error. Refer to the below screenshot.

After applying the formula, the result is shown below.

Example #2

Suppose we need to take the Total Gross Profit of the resources in the below example for 12 resources with their gross profits in column B3 to B14.

You can see that in column B13, we are getting the #NULL! Error. This is because, in the Formula bar, we have input the formula (=SUM (B2 B13)).

Suppose you want to rectify the #NULL! error you can add “Colon (:)” instead of “Space” in the formula bar (=SUM (B2:B13)) as shown in the below screenshot.

After applying the formula, the result is shown below.

Example #3

Another example shows where you are adding up Multiple ranges, and instead of adding “Comma”, we give space for those individual ranges, which as a result will give us the NULL Error and rectify that we will use Comma as the Union operator.

We need the Total Gross Profit of resources for both January and February month, so we insert the Sum formula for the Total Gross Profit (=SUM (B1:B12 C1:C12)) in the formula bar, but it will give us the #NULL! Error.

To eradicate the Null Error, input “Comma (,)” between both ranges.

After using the above formula, the output is shown below.

Example #4

In the below example, we have taken two students marks in 5 subjects in 2 different rows, which do not intersect. This is when we get the Null error in Excel.

After using the formula, the output is shown below.

To eradicate the Null Error, input “Comma (,)” between both ranges.

After using the formula, the output is shown below.

Example #5

Intersect operator is basically used when you need the values which come from the intersection of one or more columns or rows. “Intersect Operator” allows performing the calculation on the ranges that intersect.

Let us try to use the intersection operator in the below example where you need to calculate Peter’s sales in February Month. We would input the Formula in the formula bar =(B3:E3 C2:C5) in cell B7.

Once the formula is applied, we will get the sales value for Peter in February month which is 277.

If you want to calculate the sales of Peter for January and April also, you could use=SUM (Peter Jan, Peter Apr), which means we need to input the formula in the formula bar “=SUM (B2:B5 B3:E3, E2:E5 B3:E3)”.

In cell B6, to get the sales value of Peter which is 1276 for both the months. The space between the two named ranges is the Intersect Operator.

Things to Remember About NULL in Excel

• If error checking is turned on in Excel, then you can easily fix your #NULL! error by clicking the Yellow Diamond icon next to the cell, which shows the error. Click on Help or Show Calculation Steps if it’s available and pick the resolution that works for your data.
• Excel #NULL! error will appear in case of two reasons. Whether you have used an incorrect range operator or trying to use the intersect operator where there is no intersection of ranges. #Null! Error gets returned when Excel can’t figure out the range specified in the cell.
• Use of Colon, Comma, Space, and mathematical operator (plus sign (+) needs be to input correctly in the formula to avoid the #NULL! Error in Excel.
• Excel display some of the #Null! Errors which are very common. We will show you the list of those common error values along with some common causes and solutions which will be helpful to correct them. #Null! Error Values occur when incorrectly or unintentionally, a “SPACE” character is used as the intersect operator between two or more cells. This error is shown when you use an incorrect range operator in a formula. The error occurs if the Multiple cell references in a formula are separated by a space instead of a mathematical operator such as a plus sign (+).
• #NULL! error occurs when the intersect operator (the space character) is used intentionally, but specified ranges do not intersect.
