Count items within a cell

MThebeau

Looking for a formula that can count the number of items in a cell, that are separated by commas and I am stumped. So in the example below, row 2 has 3 items, row 5 has 0, the other rows have XX items. Any suggestions?

CASE WHEN `field` = '[]' THEN 0
ELSE (LENGTH(`field`) - LENGTH(REPLACE(`field`, ',', ''))) + 1

Some string manipulation options to assist.

If it's an empty array list, return 0, otherwise determine the length of the string and subtract the length of the string with the commas removed (count the number of commas). Add one because it's always one more field than the number of commas.
