Can't load JSON file?

Questions

So I tried to load this Phaser 2 example JSON file into Tiled & I get unrecognized File format. How do I import this?

    "platforms": [
        {"image": "ground", "x": 0, "y": 546},
        {"image": "grass:4x1", "x": 420, "y": 420}
    ],
    "decoration": [
        {"frame": 2, "x": 630, "y": 504},
        {"frame": 2, "x": 663, "y": 504},
        {"frame": 2, "x": 697, "y": 504},
        {"frame": 3, "x": 756, "y": 504},
        {"frame": 1, "x": 84, "y": 504},
        {"frame": 0, "x": 252, "y": 504},
        {"frame": 4, "x": 462, "y": 378}
    ],
    "coins": [
        {"x": 147, "y": 525}, {"x": 189, "y": 525},
        {"x": 399, "y": 399}, {"x": 357, "y": 420}, {"x": 336, "y": 462},
        {"x": 819, "y": 525}, {"x": 861, "y": 525}, {"x": 903, "y": 525}
    ],
    "hero": {"x": 21, "y": 525},
    "spiders": [
    ],
    "door": {"x": 231, "y": 546},
    "key": {"x": 525, "y": 336}
}

This does not appear to be a full JSON file. At the very least, it’s missing the opening brace, but it’s also missing any data on the map size, tile size, etc. It looks like this is just the last few lines of what could’ve been a valid file.

I answered on the Tiled Discord this morning, where he also posted this question:

This is an unrecognized file format, because it’s not in a format understood by Tiled. So to load it, you’d need to write a map reader that understands this format. You can currently write a reader in C++ or Python (and I’m working towards enabling writing one in JavaScript).

That said, I’m not sure if this is really what you want to do. I’m not sure about Phaser 2, but as far as I know Phaser 3 supports loading of Tiled maps saved in Tiled’s map format (not sure if TMX or JSON).
