By using the `IF` and `MATCH` capabilities together with arrays, you may create a customized method that effectively identifies and removes duplicate information.
Constructing a Customized Array System
To start, choose the cell the place you wish to create the method and enter the next line of code: “`=IF(FREQUENCY(IF((A:A<>“”),A:A),IF((B:B<>“”),B:B))>1,”Duplicate”,”Not Duplicate”)“` This method performs the next steps:
It first checks if the worth in column A (cell A1) isn’t clean and selects all non-blank values in column A utilizing the method `IF((A
A<>“”),A:A)`.
- Subsequent, it calculates the frequency of every worth within the chosen vary utilizing the `FREQUENCY` operate, which returns an array containing the frequency of every worth.
