Uploading GeoJSON file (*.json)

[NirInbal]

How do you upload a GeoJSON (*.json) file prepared in QGIS to a project?
What Datum is used/needed?
Is the location (coordinates) format relevant?
Are ITM coordinates (Israel...) is OK?

If you can export from QGIS the coordinates in lat/long format, that feature is working right now. If you need some other formats, please upload one here and i will see what i can do.
