title: Excel Formula finding max/min values
body: <p>I have two columns, a X and Y column, it has data points that when graphed (200+ data points) , it graphs a hand drawn square. My duty is to find (X,y) points of the four corners. To do so, I would need to find the minimum value of X, and the maximum Y point to get the top left corner point </p>
  
  <p>I will need to determine the maximum X point and maximum Y value to find the bottom left corner points and so on. </p>
  
  <p>However, I am not sure how to do this, because I can find the maximum/ minimum value of X/Y, but I will not find the 4 pairs of the corners. Any advice? </p>
  
  <p>Thank you</p>
