Dear everyone, We have a CSV file with 2 colums: Account Email namlh namlh.ttd1@xxxxxxxxxx tuanlv tuanlv.a2@xxxxxxxxxx tungvm tungvm@xxxxxxxxxx As you see, the first column is the account, the second column is the e-mail address (in fact, there are thousands of rows of account and email). My Windows 2003 already have all the accounts in the account column. Is there any way to create all the email in the email column corresponding to the account in the account column ? This is very urgent. Please help. Thanks so much. Ha.
