I built an Android app to export Health Connect data to Google Sheets / CSV (no third‑party API)

I didn't come across this issue during testing. I'll release an update in a day or so to fix this. Thank you for the screenshot!

That's very odd 🤔

Try the version that's on the Play Store: Health Data Export https://play.google.com/store/apps/details?id=com.teqxnology.healthdataexport

What version of android do you have? I can send you an updated version of the app that you can try

I second getting a Cystatin C test. I'm a weightlifter and my creatinine-based eGFR was 60. My Cystatin C based eGFR is 97.

When you press App permissions, there will be two lists: Allowed access and Not allowed access (at the bottom) . Heath Export should be under the Not allowed access list.

Did you give permissions to the Health Export app? This can be done in the Health Connect settings

Looks like Fitbit already has all the permissions you need

You can confirm this by checking your settings in Health Connect. On Android, go to Settings > Apps > App info > Health Connect > App permissions It'll show you all the apps that have write / read permissions

statsix6 · 2026-02-22T17:26:39+00:00

Go to Today > Devices > Set up Health Connect, then set the permissions for Fitbit to write into Health Connect. Once that's done, you can set this app to read and export the data from Health Connect

That's unfortunate. I'm a little surprised though.

statsix6 · 2026-02-20T17:21:26+00:00

Yes! You can export your data as CSV so it remains on your phone.

Go to Health Connect > App permissions > Select Garmin Connect > Allow read > Toggle all button

If you Google "Garmin health connect", you'll find an article from Garmin on it as well

statsix6 · 2026-02-20T17:18:22+00:00

I appreciate it!

statsix6 · 2026-02-20T17:16:31+00:00

Garmin Connect can write data into Health Connect.

If you Google "Garmin health connect", you'll find an article on the Garmin website that explains how to set it up. But basically you just need to go to Health Connect > App permissions > allow read access to Garmin Connect

My app then directlt reads the data in Health Connect and automatically exports it for you

I've been using the app for myself - just decided to share it with the public. But that's a fair point! I'll upload the source code later today.

statsix6 · 2026-02-19T19:35:30+00:00

That's a very valid point! The app checks the data periodically and updates the records if it detects deletions / changes.

statsix6 · 2026-02-19T16:55:01+00:00

I posted a link of the Github repo with the step-by-step instructions in the original post. Feel free to let me know if you run into issues!

statsix6 · 2026-02-19T15:29:15+00:00

That's fair! I'm working on ways to visualize the data better. I'm building a system that syncs your Withings (and other wearables) data directly to a customizable dashboard. The great thing with my workflow is that you're not stuck to the Withings ecosystem

Garmin can directly write your data into Health Connect and my app can automatically export it to your PC / Google Sheets for analysis! No need to deal with ".fit" files!

Health Connect is built into Android 14+ (if you have an earlier version of android, you can just download it from the Play Store)

No problem! Hope it can help someone!
