What coordinates: 6 digits, 8 decimals and how to convert to Lat & Lng

Question

I have found a public GeoJSON dataset that uses coordinates I can't identify. The first tuple is:

[146476.39635656,165501.27742543]

This tuple is located in Brussels, Belgium (UTM 31) and is close to [4.35659887, 50.83598669].

There should be crs definition in the geojson file like this: "crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:EPSG::23700" } } — Zoltan, Commented Mar 19, 2020 at 17:36
Thanks, it's EPSG:31370, the Belgian Lambert 72 system. I found out how to convert to Lat &Lng. I guess I can delete the question. — roland, Commented Mar 19, 2020 at 17:45
You can delete your question or you can ask @Zoltan to publish his suggestion as answer and then accept it, so that it can help somebody else with similar problem. — TomazicM, Commented Mar 19, 2020 at 19:26
@Zoltan Please publish your comment as answer. You can also elaborate on how to convert from 1 standard to another one. This is what I immediately did after having identified the standard.. — roland, Commented Mar 20, 2020 at 9:29
