Using Google Maps to track total time spent at a specific location

Question

I'm trying to use the location data of Google Maps to track the amount of time spent at a specific location. My aim is to calculate the total number of hours at my place of work, since Google Maps provides an estimate of the time I arrived and left there. I've been able to export my Maps location data using Google Takeout, but these resulting files do not appear partiularly useful. Ideally what I want is to be able to put into a spreadsheet the time I have arrived and left my place of work each day. Is there a relatively easy way to fish this out of my location data without having to manually enter the time each day? Thanks in advance
