If we highlight the TRIM function portions of the formula and press F9, we can clearly see a space at the end of the search value. Why does this newly copied and pasted dataset fail? Why did it fail? Let’s see what the reason behind the failure is along with a more robust solution. You copy and paste new data into your worksheet and apply the same function’s logic…and it fails. One of Excel’s versatile text manipulation functions, the TRIM function, can assist with the lookup function to “see” the data without the presence of the extra leading/training spaces. It is these leading or trailing spaces that Excel sees quite easily that our eyes don’t notice without special investigative steps. The number being searched appears to be in the table, yet the lookup function can’t locate it and returns an error.Īlthough this error can be caused by many factors, it is often attributed to extra spaces before and/or after one of the values ( the value being searched for or the corresponding value in the table.)
