a loop for my trials with lot of different information

Hello, I need to code a new column (for my trials) from 9 text information (in a line; 1 information in 1 column), and when one of these 9 information text changes then we go to the next trial (the first is one until the last 100) and so on knowing that single piece of information can take 32 different forms of texts without there being twice the same information on a line. Also a trial size (the number of lines for one trial) changes from one trial to another. Have you ever had this type of situation? would you have a track to be effective please?

This question is too abstract. What is "a new column", what are "trials"? "the first is one until the last 100"? What are "forms of texts"?

I've never had this type of situation.

Ok, here I give you an example, I want to find the numbers in the red column with the yellow information. It is only when at least one of these information changes I "add 1" on red column knowing that the yellow information can never be the same. Do not hesitate if need further information.
