GeoJSON is an open standard (RFC 7946) for representing geographic features — points, lines and polygons — together with their attributes as plain JSON. It's the lingua franca of modern web mapping: readable by virtually every GIS tool, library (Leaflet, Mapbox GL, OpenLayers, deck.gl) and programming language out of the box. Its simplicity and human-readability make it the natural hub format to convert to and from.
Need the other direction instead? GeoJSONL is newline-delimited GeoJSON — one feature per line. GeoJSONL — also called newline-delimited GeoJSON, NDJSON or GeoJSON Text Sequence (RFC 8142) — writes one GeoJSON feature per line instead of wrapping everything in a single FeatureCollection. That streaming-friendly layout lets tools like Tippecanoe, BigQuery and DuckDB read enormous datasets line by line without loading the whole file into memory. It's the format of choice for large-scale geospatial pipelines.

GeoJSON to GeoJSONL — FAQ
- How do I convert GeoJSON to GeoJSONL?
- Upload your .geojson file using the converter above (drag & drop or click to browse). GeoMaps converts it to GeoJSONL instantly in your browser and gives you a .geojsonl file to download. No software to install and no signup required.
- Is the GeoJSON to GeoJSONL converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert GeoJSONL back to GeoJSON?
- Yes. Use our GeoJSONL to GeoJSON converter for the reverse conversion — every format on GeoMaps converts both ways.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
