I have a column which contains a comma-separated list of numbers: "3, 5, 11"
I need like to have a continuous bunch of cells, each with the value true or false based on whether the corresponding cell value exists in the CSV string. IE cell 1 would check for "1" in the string, cell 2 for "2" in the string etc.
SEARCH() isn't a good solution, because searching for "1" would yield true even if only the value 11 exists (and not 1).
So in a sense, it's about doing a SPLIT, then searching the result of that function.
What would be the formula for that in one of those cells?
