Export history from chome browser
Solution 1:
Close Chrome, then enter the following in your command line (the exact paths will vary, the following are for Mac OS X):
/usr/bin/sqlite3 ~/Library/Application\ Support/Google/Chrome/Default/History > history.log <<EOF
select * from urls;
EOF
The history will then be in a file called history.log in your home directory (or any directory you switched to in Terminal)
Or for a user-friendly alternative, I recommend the History Trends Unlimited extension mentioned in the answer below.
Solution 2:
Also take a look at the History Trends Unlimited extension (full disclosure: I'm the developer). It does some of the analysis for you, but also has the option to export your history so you can do your own.
