I have 2 spreadsheets... One has a total of almost 12,000 urls, the other has about 6,000 URLs from the first list. The smaller list is the urls which I have completed a certain process on. I am trying to figure out a way to remove the 6,000 duplicate entries of the master file to create a list of only the URLs which have not been dealt with yet. For somebody who grew up on oracle and dbase it seems like I should be able to just run a query and make it work, but the solution is evading me. I currently have them in excel format, but can convert them to anything... Was almost there copy and pasting them into one program I have that will easily remove all duplicate entries, thought I had it there.. Then I remembered it's only going to remove 1 set of the duplicates and leave me with the master file... I need it to remove all 6,000 or so from the master list... Any suggestions on how I can do this in an automated fashion? In pseudo code I just need a simple: cross reference all cells from file 1 with cells in file 2. If cell exists in file 2, delete cell from file 1. Else do nothing. Endif.
