You can use my SQL spreadsheet app: https://superintendent.app I had a similar problem at work where I needed to do some formula on a 5 GB CSV file. Excel can't handle more than 1M rows. Database is too clunky. Eventually I built a GUI wrapper on SQLite, and it grew into Superintendent.app. - Source: Hacker News / 26 days ago

Well, shameless plug. https://superintendent.app (paid with free trial) enables you to load a bunch of CSVs and write SQL on those CSV files. It's a much faster to work with if you know SQL well. It can also handle millions of rows easily (e.g. Loading 1GB CSV file takes 10s on Macbook Pro). I initially built it because I had to identify the mismatched transactions between 2 giant CSVs using "full outer join". - Source: Hacker News / over 1 year ago

Once you've extracted it, you'll need a text editor capable of opening very large files. I use glogg which lets you open files like this without loading the whole thing at once. Source: over 1 year ago

I've been using https://glogg.bonnefon.org/. The mark / matches feature is really handy. However there are a few bugs with highlighting and it hasn't been updated in a while. Will have to check this out! - Source: Hacker News / over 1 year ago

There's a multi-platform GUI tool glogg that 's very good for browsing and searching files that break normal editors (long lines in particular tend to kill editors even with word wrap enabled). Source: almost 3 years ago

For a nice GUI log file viewer, I really like glogg ( https://glogg.bonnefon.org/ ) which is avaialble windows/mac/linux. - Source: Hacker News / almost 3 years ago
