Professional GeoJSON Tools for Developers

GeoJSON is a format for encoding geographic data structures using JavaScript Object Notation (JSON). It's important because it provides a standardized, lightweight, and human-readable way to represent geographic features like points, lines, and polygons. GeoJSON is widely supported by web mapping libraries, GIS software, and location-based services, making it essential for modern web mapping applications.

Our GeoJSON validator performs comprehensive checks including JSON syntax validation, GeoJSON structure compliance, geometry type validation, coordinate array validation, and feature property checking. It provides detailed error messages with specific paths to help you identify and fix issues. The validator checks against the RFC 7946 specification and provides warnings for best practices.

GeoJSON supports seven geometry types: Point (single location), LineString (connected line segments), Polygon (closed shape), MultiPoint (multiple points), MultiLineString (multiple line strings), MultiPolygon (multiple polygons), and GeometryCollection (collection of geometries). It also supports Feature (geometry with properties) and FeatureCollection (array of features).

Yes, our formatter can efficiently handle large GeoJSON files. All processing happens locally in your browser using optimized algorithms, so there are no server-side limitations. The tool provides real-time statistics and can process files with thousands of features while maintaining good performance.

Absolutely. All GeoJSON processing happens entirely in your browser - your data never leaves your device or gets sent to our servers. This ensures complete privacy and security for sensitive geographic data. You can use the tool offline once the page is loaded.

Formatting (beautifying) adds proper indentation, line breaks, and spacing to make GeoJSON human-readable and easier to debug. Minifying removes all unnecessary whitespace, line breaks, and formatting to create the smallest possible file size, which is ideal for production use to reduce bandwidth and improve loading times.

GeoJSON can be used with popular mapping libraries like Leaflet, Mapbox GL JS, OpenLayers, and Google Maps. You can load GeoJSON data directly into these libraries to display points, lines, and polygons on interactive maps. The formatted and validated GeoJSON from our tool is ready to use in any mapping application.

A bounding box (bbox) is an optional array that defines the minimum rectangle that contains all the coordinates in a GeoJSON object. It's formatted as [minX, minY, maxX, maxY] or [west, south, east, north]. Our tool can automatically calculate and add bounding boxes to improve performance in mapping applications.
