After the 19 May 2026 rebrand, the Fitbit app became Google Health. The export format didn't change, but your search query did. Same Takeout ZIP, same JSON files inside, same problem. Wearable Converter turns it into CSV in your browser.
If the Fitbit logo on your phone disappeared and you now see the Google Health icon, you're in the same boat as before. The app is rebranded, but the export structure is identical. Google Takeout still spits out a folder of JSON files, and you still need them as CSV before anything useful can happen.
This page covers both reasonable destinations for that data, since "Google Health to CSV" can mean a few different things depending on what you actually want next.
Two paths, same source data, same browser-based conversion.
Google Health is fine, but you want a real device. Or you've already bought a Garmin and just need your history moved across. The converter outputs Garmin Connect's required CSV format directly.
Garmin migration →You're not switching to Garmin, you just want your data outside Google's walls. Year-split CSV files plus a branded XLSX workbook with monthly and yearly summaries already calculated.
Spreadsheet export →On 19 May 2026, Google rebranded the Fitbit app to Google Health. Same servers, same accounts, mostly the same UI. A handful of features got removed or moved behind a $9.99/month AI Coach paywall, but the data export pipeline is unchanged.
That means if you used the Fitbit app before the rebrand and Google Health after, your Takeout export looks the same in both cases. The folder is still called Fitbit/. The JSON files are still named the same way. Same daily activity, sleep, heart rate, body composition records.
If you were on the original Fitbit app and never migrated your account to Google, the 15 July 2026 data deletion deadline still applies to you. Export before then or lose the data.
Same problem, different framings. Helpful if your specific search query isn't quite this one.
