How to Use ISBLANK Function in Excel for Multiple Cells

Get FREE Advanced Excel Exercises with Solutions!

ISBLANK is the function that we use to check whether a cell in Excel is empty or has value. We may use this for a cell or in a range of cells. In this article, we’ll show you how it is possible to apply the ISBLANK function in Excel for multiple cells. We have used Microsoft 365 to perform all these.

How to Use ISBLANK Function for Multiple Cells in Excel: 4 Suitable Examples

In order to illustrate, we will use a sample dataset. For instance, the following dataset represents the regular customers of a super shop. Depending on the sales of a particular day, the salesmen of that shop may bring several changes to it. We will use this dataset for the first 2 methods.Sample dataset

Method 1: Applying ISBLANK Function for Checking Multiple Blank Cells

We can use the ISBLANK function to find all the blank cells in a dataset. Suppose we wish to find all the blank cells in the above dataset. If the cell is blank, the result will be FALSE. Else it will be TRUE.


  • First, we apply the following formula in the G5.

  •  Then, if we hit ENTER, we get the whole result.

 Formula Breakdown

  • ISBLANK(B5:E13) looks for blank values in the range B5:C13.
  • The result is a new dataset consisting of the same number of rows and columns as the input dataset.
  • In the result, dataset, G5 is the result corresponding to the value B5, H5 to C5 and so on.

Method 2: Merging ISBLANK, MATCH, and INDEX Functions to Find the First Non-Blank Value of an Array

The unique 3 functions ISBLANK, MATCH and INDEX combinedly help us find the first non-blank value in an array. Suppose we want to find the first value in the C10:C13 array. We will follow the following steps to do that.


  • Firstly, we apply the following formula in the G8.

Merging of ISBLANK, MATCH, and INDEX Functions to Find First Value in an Array

  • Then, we hit ENTER and get the result.

Result of Merging ISBLANK, MATCH, and INDEX Functions

 Formula Breakdown

  • ISBLANK(C10:C13) returns an array(4 by 1) of 4 cells containing TRUE and FALSE.
  • MATCH(FALSE,ISBLANK(C10:C13),0) gives the value 3 that implies it found FALSE in the third row.
  • INDEX(C10:C13,MATCH(FALSE,ISBLANK(C10:C13),0)) looks for value from C10 to C13 and returns the value of C12 because the third entity of C10:C13 is C12.

Method 3: Combining ISBLANK and IF Functions for Finding Current Status

Often, we have to make decisions based on the availability of information. For example, in the following example we will check if any course is still available for registration by ISBLANK and IF functions. The dataset is like below.Sample datasetSteps:

  • First, we apply the formula at the E5.

Combining ISBLANK and IF Functions for Multiple Cells

  • Hitting the ENTER key, E5 gets its value.

  • After that, a Plus sign appears in the lower corner of the cell.
  • Finally, we will drag it down and the AutoFill feature fills the remaining cells.

Combined ISBLANK and IF Functions Result

Formula Breakdown

  • ISBLANK(D5) looks for value in D5 and returns TRUE as there is a value in D5.
  • IF(ISBLANK(D5),”Open”,”Closed”) returns ‘‘Open’’ because the argument of IF is TRUE

Method 4: Nesting ISBLANK, NOT, CONCATENATE, and IF Functions for Joining Text with Blank Cells in Excel

ISBLANK along with CONCATENATE function provides a special feature to join texts in Excel. In some cases, we need to combine first names with surnames. However, surnames may not always be available. In that case, we will show just the first name. Otherwise, we will combine first and surname. The dataset looks like the following image.

sample dataset


  • At first, we put the formula in D5.


  • Secondly, we will hit ENTER and D5 gets value.

  • To get the final result, we drag down and the AutoFill feature fills the value up.

Final Result of nesting Excel ISBLANK with Other Functions for Multiple Cells

 Formula Breakdown

  • ISBLANK(C5) gives the value FALSE.
  • NOT(ISBLANK(C5)) converts the value of ISBLANK into TRUE.
  • CONCATENATE(B5,” “,C5) appends Visha and Long with a space.
  • IF(NOT(ISBLANK(C5)),CONCATENATE(B5,” “,C5),B5) the argument of IF function is TRUE and in concatenates B5 and C5 with a space between them.
