Open kepler.gl JSON without QGIS or ArcGIS
You do not need QGIS, ArcGIS Pro, ArcMap, or any desktop GIS software to open and inspect kepler.gl JSON files. This page is a browser-based kepler.gl JSON viewer: it loads your file locally, renders the geometry and attributes on an interactive map, and never uploads your data to a server. If you just need to look at a dataset, check coordinates, or share what you see, you can skip the desktop GIS install entirely.
- ✓ No installation — open kepler.gl JSON directly in Chrome, Firefox, Edge, or Safari.
- ✓ No QGIS license, ArcGIS Pro subscription, or ArcMap setup required.
- ✓ Private by default — files are processed on your device, nothing is uploaded.
- ✓ Instant preview — drag a file in and see the map render in seconds.
- ✓ Good for one-off checks: a quick look at attributes, geometry, or extent before deciding whether to open the data in a full GIS.
If you later need advanced analysis, editing, or geoprocessing, you can still open the same kepler.gl JSON file in QGIS (free and open source), ArcGIS Pro, ArcMap, or Global Mapper — but for viewing and quick checks, this online kepler.gl JSON viewer is all you need.

Do I need ArcGIS to view kepler.gl JSON files?
No. ArcGIS is one option for working with kepler.gl JSON, but it is commercial software and overkill if you only need to view a file. GeoDataViewer opens kepler.gl JSON in your browser for free, with no account and no upload, so you can inspect the data before deciding whether a full GIS is worth it.
Can I open kepler.gl JSON without ArcGIS Pro or ArcMap?

Is GeoDataViewer a QGIS alternative?
For viewing, inspecting, and converting kepler.gl JSON files, yes — GeoDataViewer covers those needs entirely in the browser with zero setup.

The two complement each other: use this viewer for quick checks and QGIS when you need the full toolbox.
