compartmental Aug 2020 6:49pm, 29 Aug 2020 49 posts	0 compartmental Hi everyone, I’m a bit stumped & reaching out to the Fetch hive mind. I’m trying to consolidate all my run data from the three phase of my running life (MapMyRun, polar, Garmin) into Fetch. I’ve managed the .tcx files from MMR & the Garmin .fit files, which leaves me with 3 years worth of Polar files, which Polar have provided as .json files (naturally). The previous forum post I’ve seen have been about uploading the .gtx files from Polar & separate heart rate files but I can’t find anything about what to do with .json files. Alternatively, is there a way to get Polar to provide all that lovely data in a format I can actually use? Thank you Fetchies :D

Cerrertonia Aug 2020 6:53pm, 30 Aug 2020 13,153 posts	0 Cerrertonia You can go to an individual training session on flow.polar.com and click on the button that says export session. You can then choose whether you want .gpx, .tcx or .csv format. Obviously doing it for each session individually is painful, so I guess you're using the download all of my data feature? This seems like they're doing it to comply with EU GPDR regulations, and presumably it is what is giving you .json files. There are a couple of web services available that will download data from polar for you (findable with google) e.g. flow-exporter.ddns.net There are also various repositories on github with conversion code of the kind Sam is offering to help with.

It converts the .json files you find in your Polar Flow export into the Garmin FIT file format, mostly lossless! Garmin FIT is more common in general and you can upload those files to a lot of platforms then. tredict.com Hope you find is useful. Aldi
