How do I create a formula in excel that searches for a value in row, and then takes the value from another cell in that column?

Question

Im Trying to write a formula in excel that would basically say: IF you find in row15 the cell showing ! , THEN copy the date value assigned at the top of that column in Row2 to a new cell. Im not knowledgeable enough on excel to write the formula in the right language.

Here's the Gantt chart I'm referring to

Thanks!

Answer 1

使用INDEX / MATCH：

=INDEX($2:$2,MATCH("!",15:15,0))

Answer 2

You can define a range of cells to a variable first, then reference it and use the countif function to see if a certain value is in range. Then you could use an IF statement to see if the value from countif is true. And if it is, then print whatever you want.

range = F4:F10    # for example
=COUNTIF(range,'!')>0    #This returns true if it contains !

then you could throw in an if statement like this to print something if true

=IF(COUNTIF(range,'!'),"Yes","No")    #It will print yes if the range contains '!'

You can change the yes and no outputs to print a certain cell if you want.
