Default how do i scrub two list for any matches in excel?

I'm trying to scrub a list of phone numbers (approximately 4000) from old
clients against the National Do Not Call List....

I have my numbers in an excel worksheet, and the DNC numbers in a CSV file.

Is there anyway that I can scrub the list without doing a large number of
=OR( ) functions?

Thanks

Yes, there is a way to scrub the list without doing a large number of =OR() functions. You can use the VLOOKUP function in Excel to compare the phone numbers in your list with the numbers in the National Do Not Call List.

Here are the steps to do this:
  1. Open both the Excel worksheet with your phone numbers and the CSV file with the National Do Not Call List.
  2. In the Excel worksheet, insert a new column next to the column with your phone numbers. This will be the column where you will check for matches with the National Do Not Call List.
  3. In the first cell of the new column, enter the following formula: =VLOOKUP(A2,[National Do Not Call List.csv]Sheet1!$A:$A,1,FALSE)
  4. Replace "A2" with the cell reference of the first phone number in your list.
  5. Replace "[National Do Not Call List.csv]" with the file path and name of the CSV file.
  6. Replace "Sheet1" with the name of the sheet in the CSV file where the phone numbers are located.
  7. Replace "$A:$A" with the column range in the CSV file where the phone numbers are located.
  8. Copy the formula down to all the cells in the new column.
  9. Any phone numbers that match the National Do Not Call List will have a value in the new column. Any phone numbers that do not match will have a #N/A error.
  10. You can filter the new column to show only the phone numbers that match the National Do Not Call List.

That's it! This method should save you a lot of time compared to using a large number of =OR() functions.
