Number of users per OS major version

This tool currently does one thing — count the number of users per major OS version. To do that you need to prepare some things.

Pull your data from Google Analytics

Go to Google Analytics and export your user data as a CSV. At the time of writing you can do that by going to your project, then Reports > User > Tech > Tech details: OS version, then press the "Share this report" icon somewhere in the top right corner. Then select Download File > Download CSV.

Clean your data

Open the file you downloaded, called data-export.csv (by default) and clean it like this:

• Remove everything from the top down to the # All Users section.
• Remove all the comment # headers in the # All Users section, including # All Users comment.
• Leave the OS version,Users,New users,Engaged sessions,Engagement rate,Engaged sessions per user,Average engagement time,Event count,Conversions,Total revenue header in place.
• The header row should be on the first line.
• Make sure that the rows below the header are all data rows.
• After the data rows there should be nothing more.

Run this application

cargo run -q -- < /path/to/cleaned-data-export.csv

Result

It will output the stats per major version of the OS for the data in the CSV.
