Need Help Parsing 10M list

[cityscab]

There is a very large list of passwords that has been posted online.  I opened this file in notepad++. (it took a while to load)  When I went over it, I noticed something.  It still had all the user names listed, all the username data had been replaced with zero's.  I thought I could get around this by using --username, but some of the listings don't have any spacing between passwords and usernames, and it didn't work.  I used the gate utility to chop it up into pieces, then used notepad++ regex editor to turn tabs into newlines, so i could at least run the list against hashcat in plaintext, but unfortunately this means I am unable to run a mask without picking up 250k false positives from all the username data.  I need help parsing this list.
