CSV Analysis

Please quote on the following. It will be windows software that uses and analyses .csv files. I have attached 3 .csv's In each one, grab column 'B' (keyword) and column 'I' (Ad Count) Then combine the csv files and list the keywords in alphabetical order, deleting duplicates, and keeping the right Ad Count with each keyword. There would be two columns for; Ad Count | Keyword and a column for each csv filename Ad Count | Keyword | adbrite | bidvertiser | clicksor I want to see the common keywords in each csv file eg Ad Count | Keyword | adbrite | bidvertiser | clicksor 21 advertise on the internet x x x 20 advertise on web x 20 advertising affiliate program x x There may be more than 3 .csv files at a time so a column for each one. Would like to be able to filter. Show results that match 'x' columns i.e. show results that are only in one column, or all three columns etc. Ability to delete keywords. And export .csv
