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 (repeated terms were removed)

Be carefull to take into account all writing variants of a same element: ignore accents and diacritics allow to treat words like item and ìtém as a same word twice. Also, ignoring uppercase and lowercase allow to detect item and ITEM as a duplication of the same word and delete them.

How to count doubles in a list?

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