This isn't geojson either, it is just plain json.

See:
https://en.wikipedia.org/wiki/GeoJSON

You would need some javascript (or python) to load such object and then
based on the polygon or rectangle create n FeatureCollection/geojson
object from it (check it here: http://geojson.io).
Note that your polygons do not close (last x,y is not first one), and
your rectangles have only the bottom and top corner. So you need some
coding..

If you save that to file you can just load it into QGIS as vectordata.
