I have a google sheet https://docs.google.com/spreadsheets/d/1mUV9DpVJHC2UbyqOG49wUIRj3EflTlB9etJQFssRLvo/ with a column "Floor", it contains the number and also character, I want to query the column and remove all empty cell, =unique(query(A:A,"SELECT A WHERE A IS NOT NULL ORDER BY A"))
only the number be queried and all characters have been removed.
Can anyone advise how I can query all with unique and sort function?
