（谷歌表格或excel）如何在当前单元格上方找到最接近的匹配值，并在同一行中返回不同的列？

Question

I asked this question here , but I've hit another roadblock. I've included a visual below of what I'm trying to achieve.

For any row where Column A=x, just return the value in Column B to Column "Results". If Column A does not equal x, I want to return the closest (in distance) Column B value above the current row where Column A=x and Column B is any 3 digit number. The first part (where Column A=x) is simple, but I'm having trouble with the second part, where Column A <> x. In the linked question, I was able to use the solution to find the closest value above the current cell where Column A=x, but I have not been able to figure out how to find the closest value above the current cell where Column A=x AND Column B is any 3 digit number. Any suggestions would be much appreciated! Thank you!

Answer 1

try:

=INDEX(IF(B:B="",, VLOOKUP(ROW(B:B), 
 IF(ISNUMBER(1*B:B)*(LEN(B:B)=3), {ROW(B:B), B:B}), 2, 1)))

ISNUMBER will check for the digits and LEN will check for 3 numbers
