Matching groups of entries (rows) throughout data set <p>I am working with a large data set containing information about certain items</p> <p>The items are structured so that they all have seven main sections. Within each main section their is a variable number of parts, that the items are made of. The items uses only one part from each main section. So all items consists of seven (identical) main sections and seven parts. </p> <p>I am looking to group items togheter which are precisely identical. I mean the items that uses the same part in all the main sections.</p> <p>Is there an Excel/math wizard out there who can help me out with this? I have all the data, but I can't make Excel do this task for me..</p>
