GeoJSON Viewer

View and analyze GeoJSON files directly in your browser with our powerful mapping tool. Working from a shapefile? Export it with our Shapefile Viewer first, then inspect the GeoJSON here.

Quick start

  1. 1

    Upload Your GeoJSON File

    Drag and drop a .json or .geojson file into the upload area. If your source data is an ESRI shapefile, export it with the Shapefile Viewer first.

  2. 2

    Explore the Interactive Map

    Your GeoJSON data will be displayed on the map automatically. Use the controls to navigate, zoom, and interact with features. Click on any feature to view its properties.

  3. 3

    Export and Share

    When you've finished exploring, you can export the GeoJSON for sharing or further processing. The exported file will maintain all the original data structure and properties.

Data stays on your device

All processing runs locally in your browser. Nothing is sent to any server.

Our GeoJSON Viewer lets you view and analyze GeoJSON files directly in your browser using Mapbox GL JS. Upload .json or .geojson files, explore points, lines, and polygons on an interactive map, inspect feature properties, and export for sharing. If your data starts as a shapefile, convert it in the Shapefile Viewer first — the full workflow stays private and client-side.

Completely Private

All processing happens in your browser. Your geographic data never leaves your device, ensuring total privacy and security.

Rich Visualization

Explore points, lines, and polygons with interactive controls. Inspect feature properties and view attributes in detail.

Web Standard Format

GeoJSON is the standard for web mapping. View and validate your files before integrating them into web applications.

What GeoJSON formats are supported?

Our viewer accepts both FeatureCollection objects and individual Feature objects. The file should be a valid .json or .geojson file containing standard GeoJSON geometry types including Points, LineStrings, Polygons, and their Multi variants.

Does my data leave my device?

No. All processing happens in your browser. Your geographic data never leaves your device, ensuring total privacy and security.

What is GeoJSON?

GeoJSON is a format for encoding geographic data structures based on JSON (JavaScript Object Notation). It defines several types of JSON objects including FeatureCollection, Feature, and Geometry types (Points, LineStrings, Polygons). Unlike other GIS formats, GeoJSON is designed to be both human-readable and machine-processable.

Can I view shapefiles with this tool?

This page is built for .json and .geojson files. For .shp files or zipped shapefile archives, use the Shapefile Viewer to inspect the source data and export it as GeoJSON.

Understanding GeoJSON

JSON-Based Format

GeoJSON is a format for encoding geographic data structures based on JSON (JavaScript Object Notation). It defines several types of JSON objects:

  • •FeatureCollection — A collection of features
  • •Feature — Contains a geometry and properties
  • •Geometry — Points, LineStrings, Polygons, and their Multi variants

Unlike other GIS formats, GeoJSON is designed to be both human-readable and machine-processable, making it ideal for web applications.
