I have not bright idea about what you plan to do, but I suggest to add also numeric strings into your test data

{ "type": "Feature", "properties": { "prop0": "42" }, "geometry": { "type": "Point", "coordinates": [ 102.0, 0.5 ] } } and the common pitfall of leading zeroes { "type": "Feature", "properties": { "prop0": "0042" }, "geometry": { "type": "Point", "coordinates": [ 102.0, 0.5 ] } }
