이 함수는 Google Sheets에서도 Excel과 동일하게 작동합니다 — 구문과 인수가 같습니다.
NA()The NA function is used to mark cells as intentionally empty or missing data by returning the #N/A error value. This helps prevent calculations from including incomplete data, as any formula referencing a cell with #N/A will also return #N/A.
=NA()결과: #N/A
Returns the #N/A error value.
=IF(A1="", NA(), A1*10)결과: #N/A (if A1 is empty)
Returns #N/A if cell A1 is empty, otherwise multiplies A1 by 10.
It is useful for signaling that data is missing, which prevents other formulas from performing calculations on incomplete information.
