Since there is only one argument close the bracket We got the result as given below: Drag-drop the formula to other remaining cells.
We got the results but look at the cell B7, even though there is no value in the cell A7 still formula returned the result as a False, i. It calculates the number of characters in a given string as input. It counts the no. LEN function returned the no. So, there should be a character in it. Please select the batch. You can compare null values for equality , but the null is only equal to null:.
If either or both operands are null , the result is the null value. So, what is the catch? The if…then…else statement uses some logical value after the if word:.
When we compare almost any values of the same type, we receive the logical result: true or false. But not in the case of null — we receive a logical value as the result of comparison only when we compare null for the equality :. BUT when we compare the null for relation to the SomeValue, then the result is not logical it is null , and the if…then…else statement raises an error:. So, how to avoid this error if your data can contain nulls and replacement of the null with other value is not an option for you?
From the statements above it is obvious that we need to check value for equality with null , and if it is not equal null, then perform a relational comparison. You need to construct the correct comparison criteria, adding checking for the nulls in the first place. In my case it should look like this:. Be sure to perform the check for null in the first place! Because if…then…else construct performs consecutive calculation of criterias, and if we put the relational comparison in the first place, then the error raises and propagates to the end of the calculation chain:.
Put the null equality check in the frist place, otherwise there could be an error. Maxim Zelensky May 17, Zach Ehmann February 24, - Thanks for writing this!
It helped me understand why the null was causing the error. I also found another solution I wanted to share. In my case, the final formula looked something like this:. Edi September 20, - Maxim Zelensky October 9, - Hi Edi, cell in Excel could look like it is empty but can contain an empty string i.
For the Power Query, it means it is not empty because it contains a value. Roman July 3, -
