Fill missing dates in Google Sheets
问题 I have two columns: Col A Col B 01.02.2020 17 03.11.2020 24 03.11.2020 12 As I stated in another question, I tried to sum Col B, based on the month in Col A. The solution was the following formula (without the sort): =ARRAYFORMULA( SUMIF( MID(A:A, 4, 2), SORT(UNIQUE(MID(FILTER(A3:A, A3:A <> ""), 4, 2))), B:B ) ) Something I missed was the population of missing months. Therefore my question is: How can I populate the result table with the missing months and zeroes until values are entered? The
