CSV formatted data

Hello

First dumb post from me.

We have a script which records out-of-hours logons by staff (e.g when staff log on at the weekend, or at 1.30am, that kind of thing). Each event is recorded as single text file named after that member of staff with the reason the event was logged, in a dated folder.

You'll probably be relieved to hear that these txt files are NOT being used in Power BI! Instead, just after midnight each day, another script runs which amalgamates the previous day's logs in to a single .CSV file which looks like this:

I've changed the names, but the rest of the data is real (yes, someone really did login on Christmas Day!)

Anyway, this data is meant for HR to see if they can identify workload issues, and my idea is to produce an easy to read/use Power BI Dashboard which they can use to click on to see who logged in on a certain date, and/or click on a staff member's name to see how many times that person is logging on outside of normal work hours.

However, I know little-to-nothing about Power BI and so am struggling to understand how to use it to achieve this.

So, my question is, is the data we've got in a suitable format (can this be achieved with a .csv file containing data like the sample above)? I watched a 60 minute long YT video by Avi Singh which seemed really good, but his sample data had what seemed to be a significant advantage in that it was in an Excel format spreadsheet, with separate tables
