Manual method
Export measurements from a selected Withings profile as CSV.
- Open the Withings app and go to Profile.
- Tap Settings at the top right → Export All Health Data.
- Select the correct user profile and choose Start my archive.
- Download the CSV archive delivered by email and save it with the profile label and date.
Coverage and limitations: Available categories depend on the device. Distance and weight follow account units; temperature exports use Celsius. A household account can contain multiple profiles, so repeat only for profiles you are authorized to preserve.
Size and time to allow
Illustrative small / central / large case: 0.001 / 0.05 / 1 GB (decimal GB). These are planning assumptions, not a measured average per person. 50 MB models years of weight, blood-pressure, sleep and activity tables. Dense continuous measurements would increase this.
Preparation: Withings says an email arrives shortly without a firm SLA. Use a 5–60-minute preparation allowance as an estimate, not a promise.
For the central 0.05 GB example, network transfer alone is approximately:
| Connection | Estimated transfer |
|---|---|
| 10 Mbps | 57 seconds |
| 50 Mbps | 11 seconds |
| 100 Mbps | 6 seconds |
Assumes 70% sustained use of the stated connection. Provider throttling, many small files, retries, local extraction and copying add time. For online backup use your upload speed. These are not estimates of the provider’s preparation queue. See calculation and large-file advice.
Store and verify the archive
The example is small enough for an encrypted USB key, external drive or private cloud folder. Choose a second independent copy as well; a single USB key is easy to lose and a sync folder alone can propagate deletion. For health records, restrict access and avoid shared-family/public-link destinations; keep encryption recovery information separately.
Create withings/YYYY-MM-DD/originals/, preserve the untouched download, and extract a separate working copy when needed. Allow extra free space for archive plus extraction; compressed text can expand far beyond twice its size. Record account/scope, export date, date coverage and missing items in a local README without passwords.
Check profile identity, earliest/latest measurements, units and several data categories. Store original tables separately from edited spreadsheets. Reopen a sample from the second copy before deleting or replacing any source. Storage choices and verification.
