Wer mit Geodaten arbeitet, kennt das Problem: JSON-Exporte aus Datenbanken, APIs oder CAD-Systemen lassen sich nicht ohne Weiteres in GIS-Anwendungen einlesen. GeoJSON schafft hier Klarheit – das Format definiert Geometrien und Eigenschaften in einer Struktur, die von QGIS, ArcGIS und zahlreichen Web-Kartendiensten direkt verarbeitet werden kann. Dieser Konverter übernimmt die Umwandlung vollständig im Browser. Es werden keine Dateien hochgeladen oder auf externen Servern gespeichert – ein Punkt, der gerade im behördlichen und unternehmerischen Umfeld keine Nebensache ist. Das Ergebnis ist eine valide GeoJSON-Datei, bereit für die weitere Verarbeitung.
- Aufbereitung von Vermessungsdaten für kommunale Bauleitplanung
- Export aus AutoCAD Civil 3D zur Weiterverarbeitung in QGIS
- Visualisierung von Infrastrukturnetzen in OpenLayers-Webanwendungen
In der DACH-Region wird GeoJSON zunehmend als Austauschformat zwischen Ingenieurbüros und Behörden genutzt, da es sich problemlos in die verbreiteten Geoportale der Bundesländer und Kantone einbinden lässt. Besonders in der Schweiz unterstützen kantonale GIS-Plattformen wie map.geo.admin.ch den direkten Import von GeoJSON-Dateien.
About JSON to GEOJSON Conversion
Short answer: yes, you can convert JSON to GEOJSON online for free, and quality is well preserved with the right settings. Just upload your .json file to CocoConvert, pick GEOJSON as the output, and click Convert. The whole process takes seconds.
Now for the details. JSON (JavaScript Object Notation) is the universal data interchange format for APIs and configuration. GEOJSON is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your JSON file is decoded and re-encoded as GEOJSON. Converting JSON to GEOJSON maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is JSON to GEOJSON conversion free?
Yes. CocoConvert offers free JSON to GEOJSON conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is JSON to GEOJSON conversion?
Most files convert in 2–10 seconds depending on size. Large code / data files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded JSON file and the converted GEOJSON file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting JSON to GEOJSON lose quality?
Converting JSON to GEOJSON maintains high quality with CocoConvert's optimised encoder settings.
Can I convert GEOJSON back to JSON?
Yes, CocoConvert supports GEOJSON to JSON conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
