If I have two speadsheets. One with multiple columns and some rows have missing data. So if I have spreadsheet one with 10 fields and two of them are "Email" and "Website" and lets say, quite a few are missing email data. Now I have spreadsheet 2 which only has 2 columns; "Email" and "Website". So can I merge these so that everywhere "Website" on spreadsheet 2 matches spreadsheet 1, it fills in the missing email data? For example: Spreadsheet 1: Spreadsheet 2: How could I take those two and merge them correctly.
