excel - How to filter symmetric words from a column of data?

Question

I have a list of words and I would like to find all symmetric words and some how put value 1 for each of them (see the picture).

Answer 1

This does the trick:

=1*(A1=CONCAT(MID(A1,LEN(A1)-SEQUENCE(1,LEN(A1),0),1)))

It reads the string in a cell backwards using MID and SEQUENCE, and compares the CONCAT result with the original to see if it is the same, i.e. the string is symmetric.

Multiplying by 1 forces the Boolean into an integer.
