File search program

I need a program that will scan a .CSV file and create a new .CSV file with all the email addresses from the first file. I have attached a .CSV file with several columns. This file is an export from Outlook 2007. It includes all the emails received over a period of time. One of the columns ("Body") contains a large amount of information. I need a program that will search each column (as defined in the program) and find any and all email addresses in that column. For example, I want to be able to search the "Body" column and find all the email addresses in that column. The program should create a new .CSV file that has a list of all the email addresses from the first file. The only information needed will be emails. The remaining data can be discarded and doesn't need to be recorded. I need to be able to select the file to be searched. I need to be able to select the column to be searched. I need to be able to select more than one column. I need to be able to select the name for the new file. ## Deliverables I have attached the sample file, because the actual file is over 450MB.
