How to Use the GeoJSON Viewer

Our interactive GeoJSON Viewer allows you to instantly visualize geographic data structures on a map without needing desktop GIS software.

Upload a GeoJSON File

You can upload any standard .geojson or .json file from your computer using the file browser or by dragging and dropping the file into the upload zone. The viewer will automatically parse the data and zoom the map to fit all features.

Paste GeoJSON

If you have a GeoJSON string copied to your clipboard, you can use the Paste tab to directly input the JSON code. Click "View on Map" to instantly render the geometries.

View GeoJSON on the Map

Once loaded, the map will display your points, lines, and polygons. You can click on any feature directly on the map to inspect its properties, or browse the list of features in the sidebar panel.

What Is a GeoJSON Viewer?

A GeoJSON map viewer is an essential tool for developers and GIS professionals to quickly inspect geographic data. GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes. Based on JavaScript Object Notation (JSON), it is widely used in modern web mapping. By using our online GeoJSON viewer, you can easily validate your datasets without installing complex desktop software. Whether you need a GeoJSON file viewer or a quick GeoJSON visualizer, this interactive map tool provides everything you need in one place.

Supported GeoJSON Types

This visualizer fully supports the GeoJSON specification (RFC 7946), including:

Geometries: Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, and GeometryCollection.
Features: A spatially bounded entity with associated properties.
FeatureCollections: A list of multiple features within a single JSON object.

Frequently Asked Questions

Is my GeoJSON file uploaded to a server?▼

No. Your GeoJSON file is processed entirely in your web browser. No geographic data is sent to our servers, ensuring your privacy and the security of sensitive datasets.

What GeoJSON geometry types are supported?▼

The viewer supports all standard GeoJSON geometries: Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, and GeometryCollection, as well as Feature and FeatureCollection objects.

Can I inspect the properties of each feature?▼

Yes. You can click on any geographic feature on the map, or select it from the feature list, to view its associated properties and data attributes.

Is there a file size limit?▼

Because processing happens locally in your browser, the maximum file size depends on your device's memory and processing power. However, extremely large datasets with hundreds of thousands of complex features may cause the browser to become unresponsive.
