望有人可以解答!
----------------------
約40,000個email addresses save左係一個excel file裡面
一行一個entry, like this:
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
當中有d email可能會重覆
有咩最快方法可以搵到重覆左既email,
跟住delete左duplicate emails
雖然我知可以續個續個email Ctrl+F 咁樣search
但40,000幾個entries根本冇可能
有冇高人可指點?
