Dealing with blank cells or ranges in Excel can be a crucial part of data management and analysis. Whether you need to identify, fill, or skip blank cells, understanding how to check for them efficiently is essential. This guide provides simple yet effective methods to determine if a cell or range is blank in Excel, with practical tips to enhance your data handling skills.

• If a cell is blank then return specific text
• If a cell is blank then stop calculating

Check if a cell is blank

This section is divided into two parts for straightforward identification of blank cells in the specified range. The first part demonstrates how to return specific text when a blank cell is encountered, while the second part shows how to halt formula calculations when encountering a blank cell.

If a cell is blank then return specific text

As shown in the shipment table below, if the item is delivered on time, it will be marked as Delivered in the Shipping Status column. If delayed, the Shipping Status remains blank. To identify the blank cells in this column to check for the delay delivery, you can do as follows.

Select a blank cell to output the result (such as I2 in this case), enter the following formula and press the Enter key. Then select this result cell and drag its Fill Handle down to get the rest of the results.

=IF(ISBLANK(F2), "Delay", "Completed")

If a cell is blank then stop calculating

In certain situations, when a formula encounters a blank cell, it may return an error or unexcepted result, depending on the specific function and settings applied in the sheet. In the example below, I'm using the formula =(C2-B2)/B2 to calculate the percentage change between the previous month and this month for different products. However, when the source cell is blank, the formula produces a #DIV/0! error. This section will guide you on preventing this error when dealing with blank cells.

Select a cell (such as D2 in this case), enter the formula below and press Enter. Select this result cell and drag its Fill Handle down to get the rest of the result.

=IF(ISBLANK(B2), "", (C2-B2)/B2)

As you can see from the above results, all the error values have disappeared although there are blank cells.

Check if a range is blank

If you want to check whether a certain range is blank, the formula in this section can do you a favor.

Here I will take the range G1:K8 as an example. To check whether this range is blank or not, do as follows.

Select a blank cell to output the result, enter the following formula and press the Enter key.

=IF(SUMPRODUCT(--(G1:K8<>""))=0,"It is blank","It is not blank")

Tips: Highlight blank cells

Highlighting blank cells helps easier identify and address blank cells in large datasets. This section will explore how to visually highlight blank cells in your data set using Excel’s Conditional Formatting.

Step 1: Select the range where you want to highlight the blank cells.

Step 2: Open the New Formatting Rule dialog box

Under the Home tab, click Conditional Formatting > Highlight Cells Rules > More Rule.

Step 3: Create a conditional formatting rule

In the New Formatting Rule dialog box, you need to configure as follows.

1. Select Blanks from the Format only cells with drop-down list.
2. Click the Format button to specify a fill color for the blank cells.
3. Click the OK button to save the rule.
   

Result

All blank cells in the selected range are highlighted with specified fill color.

In summary, this guide teaches efficient ways to check and manage blank cells or ranges in Excel.
