The above screenshot shows a simple example. The data is in the range B5:D22. The goal is to identify the rows in the data zone which are appearing in the Resigned Members list, in column F. You can delete these unnecessary rows later.
Steps:
- Firstly, select Cell D5.
- Then, insert the following formula.
Here, the COUNTIF function of the formula will return 1 if it (bold part) matches a list value(Cell range F5:F11) with a data value (Cell C5). If this part returns 1 or more, then the IF function will return “Resigned”, otherwise nothing.
- After that, press ENTER and drag down the Fill Handle tool to AutoFill the formula for the rest of the cells.
This whole formula will display the word “Resigned” if the “Member Num” in column C is found in the “Resigned Members” list. If the Member number is not found, it returns an empty string.
- Now, this whole formula will display the word “Resigned” if the “Member Num” in column C is found in the “Resigned Members” list. If the Member number is not found, it returns an empty string.
You can sort the list by column D, the rows for all Resigned Members will appear together and can be quickly deleted.
