It'll work with file format converters but some data will be missing. Notably time stamps. Occasionally when Strava and/or Wahoo Fitness apps failed, I've fallen back on Google maps timeline data to recreate the ride for Strava. It sorta works but lacks the time stamps for segment times. But it does recreate the total route pretty well.
For this to work you'd need to enable Google maps timeline to track your activities by default. I've done this all along with my Android phone so I'll have some backup evidence in case something happens and I'm unconscious and can't remember what happened or where it happened.
That was useful last year when I was hit by a car. I didn't lose consciousness but it did confirm my version of events. And Google maps timeline also records all of my locations so I have a tamper-proof diary of my many medical appointments related to the injury. Very handy because I don't always remember to manually enter notes in my journal, especially on bad days or when I was in the hospital.
Google data can be downloaded and edited, but the original data recorded and stored by Google cannot be tampered with by users. We can delete it entirely, but not tamper with the original data file. So that may be admissible in court if necessary.
Google maps timeline tracking can be set to private by default. Only you, Google, the NSA and every hacker in Russia and China will know. That's about as private as data gets nowadays. We can choose to make our activities public but I don't.
