How to compare data across calc worksheets

I am looking to compare data from two separate worksheets.

Unfortunately the data is not formatted the same.
One is a do not call list and one is a list of leads.
one is formatted in a single cell as (###)###-#### and the the other is formatted across two cells. first cell area code ### and second cell #######

I am assuming I first need to make the formatting the same in both? If so and suggestions? Macro? Manual data entry (I hope not but do have admin staff…)

Thanks

vlookup didn’t do exactly what I wanted but is workable.

If you compare two cells, it is the values of those cells being compared and not the formatting.

Assuming the data is in columns, I guess you may need to create one or two new columns to manipulate the original values into a common form (edit out the brackets if they are part of the data, combine two cells into one). You can then reliably compare the data in the new columns.
