Workout App Export JSON

If you search for workout app export json, you usually care about portability: you want your plan and history to survive app changes. This guide covers what to look for when you want to workout app export routine data.

This is not only a “power user” concern. Even if you never touch the export file, a clear export story is a signal that the product respects data ownership and long-term trust.

What people mean by “JSON export”

A portable file format you can store yourself
A documented workout json format (not an opaque blob)
A stable way to re-import or migrate later

What should be exportable?

“Export routine” is often shorthand for multiple things. If you are evaluating any workout app, check whether you can export:

Routines/workouts (the plan: exercise order, sets, reps, time blocks)
Exercise library (the names + notes you rely on)
Training log/history (what you actually completed)

What makes a good workout JSON format

A good format is boring in the best way: consistent, versioned, and easy to interpret later. The goal is portability without guesswork.

Versioned schema so old exports don't break
Stable IDs so exercises and logs stay connected
Human-legible fields (not just compressed blobs)
Clear unit semantics (kg/lb, seconds, rounds)

Example structure (illustrative)

You don't need this exact shape. But you want something that looks like structured data, not a mystery string:

{
  "schemaVersion": 1,
  "workouts": [
    {
      "name": "A Day",
      "blocks": [
        { "type": "setsReps", "exercise": "Pull-ups", "sets": 5, "reps": 5 },
        { "type": "timer", "label": "Rest", "seconds": 120 }
      ]
    }
  ]
}

Open formats and APIs

Some searches are specifically about an open workout format app or a workout tracker with api. Others are about being able to run the whole thing yourself, like a self hosted workout tracker alternative. These are valid requirements if you have strong data ownership needs.

If you truly need an API, be clear about the use case: sync to a spreadsheet, build dashboards, connect to your own coaching tooling, or just keep a long-term archive. “Has API” can mean anything from a private endpoint to a well-documented public interface.

Portable routines

If you want portable workout routines, look for products that make export and migration explicit: documented formats, predictable structures, and a commitment to compatibility.

Can you export without a paid tier?
Can you export from both iOS and Android?
Can you restore from export on a new device?

How this connects to privacy

Export is also a privacy signal. If you care about local-first behavior, look for clear statements about where data is stored and how backups work. Start here: Privacy Policy.

FAQ

Is JSON export the same as an open format?
Not necessarily. JSON is a container. “Open format” is about documentation, stability, and compatibility over time.

Do I need an API?
Only if you want integrations. Many people just want a file export so their routine and history are portable.

What if I only want to export routines, not logs?
That can be enough if you mainly care about planning portability. If you care about progress review, exportable logs matter too.

What should I store from an export?
Keep it like any other important file: in your normal backup flow (cloud drive, encrypted archive, external drive).
