Import & export

Your data leaves when you say so.

CSV for a spreadsheet. JSON for the full profile. A password when you want one. And a preview before an import touches a single reading.

Export

Take a copy you can actually use.

Choose the format, the date range, and where the file goes. The app does not upload it.

CSV — weight history

A simple table for a spreadsheet or another app: date, time, weight, unit, notes, and context.

JSON — full profile

A structured export of the profile, with a date range and an optional extra display-weight column.

Password protection

Protect a CSV or JSON export with AES-GCM. The password cannot be recovered; keep it safe.

Plain files are readable by anyone who opens them. Password protection is optional, and a lost password cannot be recovered. If you need the full record including photos, use the local backup.

Import

A preview before the commit.

Import is not a blind overwrite. You see the rows, the errors, and the duplicates before anything changes.

Step 1

Choose a file

Pick a Weight Track Assistant CSV/JSON export or a CSV from another app.

Step 2

Preview first

See valid rows, row errors, duplicates, and the date range before importing.

Step 3

Map the columns

Choose date and weight columns; optionally map time, unit, note, meal, and timezone.

Step 4

Review duplicates

Skip, keep both, or merge. Apply one choice to all, then adjust individual rows.

Step 5

Pick a target

Import into a new profile or merge into the current one. Merging backs up the profile first.

Step 6

Import & report

Invalid rows must be fixed or removed. Save the error report if you need to edit outside the app.

Bring data in

CSV from another app is welcome.

Already have a weight history in a spreadsheet or another app? Map its date and weight columns, set a unit and timezone if the file lacks them, and review the preview.

  • Weight Track Assistant CSV or JSON exports are recognized directly.
  • Other apps’ CSVs can be mapped column by column.
  • Rows with errors are reported before import; save the report to fix them.
  • Import into a new profile to keep the current one untouched.
Safety net

Back up before you merge.

Merging into an existing profile requires a pre-import backup. Existing readings are not replaced; duplicates follow your review choices. Cancelling makes no changes.

Import into a new profile if you want a clean comparison. The current profile stays as it was.
Back up and restore section with Create backup and Restore backup buttons.

Full backup

A local .zip for the whole profile.

The full backup includes the profile and photos. Restore creates a new profile; existing profiles are not changed.

  • A local .zip file — nothing is uploaded.
  • Includes progress photos.
  • Not encrypted; store it somewhere you trust.
  • Restore creates a new profile, so you can compare before deleting anything.

Scope

What JSON import covers — and what it does not.

Be precise about the format. It saves time and prevents a disappointing restore.

JSON import restores

  • Weight history.
  • Profile details.
  • Delete markers from the export are skipped.

Use full backup for

  • GLP-1 records.
  • Nutrition, hydration, and workouts.
  • Body measurements and progress photos.
No cloud sync. Export and import are files you control. For moving phones, email support if you want help; Android device transfer does not move the app’s health database or photos.

Import & export questions.

Do I need to export/import to update to 4.2?
No. Updating in place upgrades your existing data automatically. Export and import are for backups, moving to a new phone, or bringing data in from another app.
What can I export?
CSV for weight history, or JSON for the full profile. Choose a date range, an optional extra display-weight column, and optional password protection. The file goes only where you choose.
What can I import?
A Weight Track Assistant CSV or JSON export, or a CSV from another app with column mapping. The preview shows valid rows, errors, duplicates, and the date range before anything is written.
How are duplicates handled?
For each duplicate you can skip it, keep both readings, or merge. You can apply one choice to all duplicates, then review the rest.
Does JSON import restore everything?
JSON import restores weight history and profile details. Use Restore backup for other modules such as GLP-1, nutrition, measurements, and photos.
Is the full backup encrypted?
No. The full local .zip backup is not encrypted, so store it somewhere you trust. CSV/JSON exports can be password-protected with AES-GCM; the password cannot be recovered.
Can I undo an import?
Cancelling makes no changes. A pre-import backup is required before merging into an existing profile, and importing into a new profile keeps the existing profile untouched.
Does the app upload my export?
No. The file is written where you choose. Weight Track Assistant does not upload it. See the privacy page.
