Hello,
Could you please help me to understand how to export from mapshaper into GEOjason without losing the name (key field) to the polygon and then import to Power BI?
I managed to load OSGB_Grid_1km into mapshaper including the grid name field but when exporting in GEOjson it loses the grid reference numbers (e.g. NG6612). When loading it into powerBI I then have no key fields available to map to my CVS. (see my screenshots below)
Where can i find a OSGB Grid 1km GEOJason shape file (with OSGB_Grid_1km key fields) which I could use in order to reference and then visualise my CVS file?
Unfortunately I am not a GEOJason expert and rely on mapshaper’s export. Any pointers would be greatly appreciated.
Thanks
Polina

Hi @Polina,
As the issue occurs when convert GeoJSON maps into the TopoJSON format use map shaper tool, I would suggest you contact map shaper engineer for help: https://www.npmjs.com/support.
In addition, there is a collection of the TopoJSON map files you can check if one sample suit for you: TopoJSON Map Files for Power BI Shape Map.
Best Regards,
