Finding the 10 largest values in Excel without sorting 
also applies to dates and text as well
For any selected range containing numeric data, you can quickly list the ten amounts which are the most (largest) values within the range. If you wish to list a number of values other than 10, just specify the quantity (e.g. 5, 20, 50, etc.) on the "Other" text box. This technique provides the auditor a quick way to identify such values.
Note that the data does not need to be "pre-sorted".
First, select a range in Excel which contains the numeric values to be tested:
Step 2 - Select the menu item "Numeric tests|Extreme Values"
Step 3 - Specify the name of the Excel work book
Step 4 - Using an Explorer type interface - locate the workbook
Step 5 - Select the name of the sheet containing the data
Step 6 - Select the numeric column to be tested
Step 7 - Specify the number of items - e.g. top 10
Step 8 - Click the "Run" button.
Step 9 - View the results in a grid. Note that the results are also written out to a text file for easy import back into Excel.
