There is a table of data that consist of date and city.
The city may appear more than once in a date.
I want to make a new table with FILTER or UNIQUE or some other formulas that can get a new table that consists of date and unique city (without duplicates)
The example can be seen in this link: https://docs.google.com/spreadsheets/d/15-PauS118Nm9CWNaIEwwsOvyX0jWVzfeZHIJMmZ_j9k/edit?usp=sharing
