Regex to only keep email:password

Solution 1:

This will match email only after EmailPass :

• Ctrl+H
• Find what: .+?EmailPass : (\S+@\S+)
• Replace with: $1\n
• UNCHECK Match case
• CHECK Wrap around
• CHECK Regular expression
• CHECK . matches newline
• Replace all

Explanation:

.+?             # 1 or more any character, not greedy
EmailPass :     # literally
(               # group 1
    \S+             # 1 or more non space
    @               # @
    \S+             # 1 or more non space
)               # end group

Replacement:

$1      # content of group 1, the email
\n      # a linebreak, you can use \r\n for Windows EOL
