Answer 1

Pivot tables: the single most underutilized and powerful feature of excel.

• File menu:
• Insert
• Pivot Table
• Select range
• Fill in as indicated in image below

Step by Step:

• Place cursor in cell to right of all data on sheet.
• Select insert from menu
• select pivot table icon
• select pivot table from pop-up of icon
• use the button to select the range of cells included (all 600+ rows in 2 columns) (or just enter $A:$B)
• select ok
• A pivot table field list appears on the right:
• Drag and drop row 1 into row labels.
• drag and drop row 2 into values area.
• left click on "... of Row 2"
• select value field settings
• select "Max" instead of count or sum
• select ok and you should have desired results.

The pivot table will find the max value in row 2 for each unique value in row 1 which is what I believe you are after.
