Make changes to the data file comparison project already completed.

This is an update to already completed project. This will be a private bid available only to the freelancer (alquarizm) who completed the original project. 1. Change the input and output format into CSV file. Instead of reading/writing to excel i would like the new version to read from and write into a csv file. (The format would be exactly the same as in excel file I've sent previously). User should have the following interface controls: a) Select Vantage file: (this is the file with 9 character entries where last character on the right has to be removed) b) Select Sigma file: (this is the file with 8 character entries) c) Choose destination file: (user should be able to choose the destination and name for the output CSV file). 2. Add stats: I would like to provide the following summary at the end of the output file: a) Total number of entries processed: #; b) Number of exact matches: #; c) Number of instances where there are entries in Sigma (second file) but no entries in Vantage (first file): #; d) Number of instances where there are entries in Vantage but no entries in Sigma: #; Please create this as a separate project from the first one. Please send me two separate archives with both complete projects, i will install netbeans and go over the code - I am very interested in how it is done programmatically. Thank you very much, Yan.
