In this tutorial, we’ll show you how to identify errors in Excel, as well as how to count them. This tutorial provides you with the knowledge and tools you need to efficiently identify and troubleshoot Excel spreadsheet errors.
Suppose that we have an Excel list of data, and in it there are some errors. We want to know which cells contain errors. To do this, we will use the ISERROR function. The ISERROR function in Excel is a built-in function that is used to check if a cell contains an error. It returns a boolean value, which means it will return either TRUE or FALSE. If the cell contains an error, the function will return TRUE, and if the cell does not contain an error, the function will return FALSE.
Here’s an example of how you can use the ISERROR function:
=ISERROR(A1:A7)
You can also use the ISERROR function in combination with other functions and formulas to count the number of errors in a range of cells. For example:
=COUNTIF(B1:B7,”TRUE”)
In this example, the COUNTIF function is counting the number of cells in the range B1:B7 that contain an error, as determined by the ISERROR function.
You can also use the IF function to manipulate and customize your own boolean value. So, instead of “TRUE,” you can change it to the value of “1” and “FALSE” into an empty value. For example:
=IF(ISERROR(A1:A7,”1”,””))
Conclusion
The ISERROR function in Excel is a useful tool for identifying and troubleshooting errors in your spreadsheets. It returns a boolean value, either TRUE or FALSE, depending on whether a cell contains an error or not. This function can be used in combination with other functions and formulas, such as COUNTIF, IF, and so on, to count the number of errors in a range of cells or customize the boolean values. By understanding and effectively using the ISERROR function, you can improve the accuracy and reliability of your Excel data and make your workflow more efficient.
