How do I use Array

Do you mean, containing multiple groups of text in the same cell? For example, use the "|" symbol to split:

Apple|Banana

Then when you use Array.At() to get the text, you can continue to use System expressions tokenAt() to extract the words.

tokenat("Apple|Banana", 0, "|") returns Apple.

-------------------------

If you are not sure how many group there are,

Apple|Banana|Carrot|Durian

you can also use tokencount to get the words count, Then iterate it with System conditions For or Repeat , and then use loopindex expression to get the index.

text = Array.At()

Repeat tokencount(text, "|") times

word = trim(tokenat(text, loopindex, "|"))

-------------------------

As an additional, you can also use trim(), to remove the space between them.

Apple | Banana

So they might be

text = Array.At()

word = trim(tokenat(text, 0, "|"))
