The problem

Moving platforms
shouldn't mean
losing everything

Years of health data locked in Fitbit. Garmin's import process is powerful — but only if you know exactly how to prepare your data.

01

Wrong format

Fitbit exports in JSON. Garmin Connect only accepts a specific CSV format that's not documented anywhere obvious. Most people give up here.

02

Multiple files

Your Fitbit history is split across hundreds of individual JSON files — one per data type per month. Merging them manually is hours of work.

03

Unit mismatches

Fitbit stores data internally in imperial regardless of your display settings. Without the right conversions, your data lands in Garmin completely wrong.

How it works

Four steps.
Done.

No technical knowledge needed. If you can download a file and click a button, you can do this.

📦

Export from Fitbit

Request your data from Google Takeout. You'll receive a ZIP file with your complete Fitbit history.

⚙️

Drop your ZIP into Wearable Converter. It runs entirely in your browser — your data never leaves your device.

FAQ

Common
questions.

Is my data safe?
Yes. The converter runs entirely in your browser — your Fitbit data is never uploaded to any server. We never see it, store it, or have access to it. The only thing that touches our servers is the licence key validation.
How do I get my Fitbit data?
You need to request a Google Takeout export that includes your Fitbit data. Go to takeout.google.com, select Fitbit, and request a download. Google will email you a link to a ZIP file — that's what you drop into Wearable Converter. The process usually takes a few minutes to a few hours depending on how much data you have.
How long does conversion take?
For most people with 2–4 years of data, conversion takes 30–90 seconds in the browser. Importing into Garmin Connect takes a few minutes more — you upload one CSV file per year.
Why does Garmin sometimes show an upload error?
This is a known bug in Garmin Connect's importer that affects all CSV uploads — not specific to our files. The data almost always imports successfully despite the error message. Simply retry the upload and it will go through. Garmin is aware of the issue.
What if I need to convert again?
Your licence key gives you unlimited access. If you download a second Takeout ZIP, need to re-run with different settings, or want to re-import after an issue — just come back and use it again.
Why isn't all my data transferring?
Some data types — like heart rate history, sleep stages, and individual workout details — simply cannot be imported into Garmin Connect. This is a limitation of what Garmin's platform accepts, not a limitation of our tool. We transfer everything Garmin allows.
Do I need to create an account?
No account needed. After purchase, you receive a licence key by email. Enter that key on the tool page and you're ready to go.
