I have a large database of car makes and models color auto code structured in these columns: Make - Model - Description - Code and about 8000 rows.
I need to have the database with only the first occurrence of each Make - Model - Desc - Cod with same Make - Model
example:
MAKE - MODEL - DESC - CODE
Alfa romeo - 145 - Blue - 205
Alfa romeo - 145 - Black - 201
I Should only have the first row of each individual make and model in my libre office Calc sheet
so in the above example I should have only
Alfa romeo - 145 - Blue - 205 and so on for every make and model…
How could I do?
I tried with the simple filter, inserting the two affected columns equal to non-empty and arriving the duplication, but not work I tried with the countifcondition, but I didn’t quite understand how to use it in this case.
Thanks for help
