In a list of emails (one per line), similar to this:

How to use regex to mask the emails (for GDPR) by replacing every character between the first and last before @ with * ?

So we get this:

Or alternatively, just insert a set number of asterisks (for example, 5) after the first character and @, like this:

I’ve been struggling with this the whole morning and got nowhere…

Please help :(

  • For your first goal, I propose this regex S/R :

    • SEARCH (?!^).(?=.*.@)

    • REPLACE *

And you end up with this OUTPUT text :

e****1@gmail.com
s***********l@icould.com
t********l@yahoo.com

  • For your second goal, I propose this regex S/R :

    • SEARCH (?!^).(?=.*@)

    • REPLACE *

And you end up with this OUTPUT text :

e*****@gmail.com
s************@icould.com
t*********@yahoo.com

For each case, check the Regular expression search box !

Best Regards,
