I don't think you can specify that directly, though here is a workaround:
- Add another delimiter character to your string. So replace
,
with say,|
- Now when you split with
,
, we know for sure that even empty columns will have a character (in this case|
) - Use replace to substitute the extra delimiter
|
with a blank string - Since output of
split
is an array, you will need to usearrayformula
Here is what the final formula would look like
=arrayformula(substitute(split(substitute(A1,",",",|"),","), "|",""))
