COUNTBLANK Function in Excel
In this tutorial, you will learn the usage of the COUNTBLANK excel formula. COUNTBLANK function in excel is useful to count how many blank cells that you have in a range.
Why do We Need to Learn COUNTBLANK Excel Formula?
When using spreadsheets, sometimes we want to check whether there is a blank cell in our range and if there is, then how many are the blank cells. The checking process can be needed for some reasons such as making sure there is no wrong or error processing result if we use a formula to process every data entry in the range or check whether there is still incomplete data if we get the data from external sources.
As an example of the need in our work, imagine we are doing a lookup process for a data variable of our company’s products to complete the analysis that we do by using the reference of the company’s products detail information table in the spreadsheet. If we want to use formulas like INDEX MATCH or VLOOKUP to help speeding up the process, then we must make sure that all the data which is made as the lookup value for the search process is there for each product and all the data that we want to find are there in the reference table. However, there might be some blank cells in our database or reference that can be undetected considering the very high amount of data entries that we must see in the database or reference. This is, of course, dangerous because it can give a negative impact on the result from our data analysis if the data of even just one product cannot be found so it will produce an error from the usage result of our formula.
If we need to see one by one manually to make sure there is no empty cell, then it can take a long time to do it, especially if there are many data entries to check.
Because of that, to help you in faster empty cells checking in a range on the spreadsheet significantly, you can use COUNTBLANK function in excel. COUNTBLANK excel formula can help you to count how many blank cells are there in your range. It is very useful to be learned if you often deal with things related to the counting of empty cells in your data processing as in the above case.
