What type of data is being provided and how to process it?

Question

I want to export parcells from a turkish website (https://parselsorgu.tkgm.gov.tr/) to process them in my local GIS. When I press the "download coordinates" (Koordinat İndir) button, I receive the following Code as a .txt-File.

Does anyone know what to do with it?

Answer 1

Looks like GeoJSON file, You can view it by copy pasting the feature in geojson.io. Save the file with the .JSON extension instead of the .txt and you should be able to use it.

Answer 2

That's data in GeoJSON format. You can use it for example in the free GIS suite QGIS.
