Return a Blank Cell in Excel

Understanding Blank Cells

Excel recognizes different types of "blank" cells. A cell can appear blank but may contain an invisible character or a formula. Excel does not have a null constant, making it challenging to handle blank cells. However, several methods and formulas can be utilized to return or identify blank cells effectively.

Formulas to Return Blank Cells

To return a blank cell in Excel, use the formula =IFERROR(MID(Q2, FIND("",Q2), FIND("",Q2) - FIND("",Q2) + 1), ""). This formula extracts text from a cell (Q2 in this case) and returns a blank if an error is found, which happens if the text to find is not present. Another method is to use =IF(A1=1,B1,""), which will leave the cell visually blank if the condition is not met, although not truly blank.

Checking for Blank Cells

To check if a cell is empty, apply the =COUNTBLANK(C1)>0 formula, which will return true if C1 is blank or contains an empty string (""). The LEN function is also a viable option to check for non-visible characters in a cell. The =LEN(C1)=0 formula will return true if the cell is empty.

Truly Blank Cells

To make a cell truly blank, where it is "blank" due to a formula, use the =N(C1) function. This function will return a blank cell when the targeted cell contains a formula that otherwise leaves it visually blank.

Splitting Text and Returning Blank

The formula =IF(A1>"", MID(A1, 1, FIND(" ", A1)-1), "") is used to split text from a cell if it's not empty and return a blank value if the cell is empty. For instance, it returns "Hello" from cell A1 containing "Hello World" or a blank if cell A1 is empty.

Using Macros for Blank Cells

The clearBlanks VBA macro can be employed to remove contents from cells that display an empty string (""). This is an advanced method suitable for cleaning up multiple cells at once.

Common Use Cases

• 
  Creating cleaner looking data by avoiding display of zero values
• 
  Generating reports that only show cells with significant data
• 
  Preparing spreadsheets for presentation where only non-empty cells are relevant
• 
  Facilitating the use of functions that need to ignore blank cells
• 
  Streamlining data visualization by excluding blanks from charts or graphs
