Answers to Questions

How to remove doubles in a list?

Indicate / copy-paste items in the List field. dCode detects if the list is a list of terms (one per line) or a list of words (with separator) and finds redundant items repeated more than once in order to un-duplicate.

Example: A,B,C,D,A,B,C,A,B,A can be deduplicated as A,B,C,D

Be carefull to take into account some options

Option 1: ignore diacritics, in this case words with accents like item and ìtém are duplicates, else not.

Option 2: ignore uppercase and lowercase, in this case item and ITEM are duplicates, else not.

How to count doubles in a list?

By listing items, dCode counts the number of appearance of each, the list can be sorted to detect the most duplicated ones.
