About GeoJSON Sequences

GeoJSON Sequences (also called newline-delimited GeoJSON or GeoJSONL) is a streaming format where each line of a text file is a complete GeoJSON Feature. It is designed for efficient processing of large datasets with line-oriented tools, streaming APIs, and big data pipelines.

You might convert from GeoJSON Sequences when you need to load the data into a GIS that expects a conventional GeoJSON FeatureCollection, when you want to import the features into a database, or when a downstream tool does not support the newline-delimited variant of the format.

Frequently asked questions

What is the difference between GeoJSON and GeoJSON Sequences?

Standard GeoJSON is a single JSON document containing a FeatureCollection array. GeoJSON Sequences uses one Feature per line as a self-contained JSON object, making it possible to process very large datasets line-by-line without loading the entire file into memory.

What file extensions do GeoJSON Sequences files use?

Common extensions are .geojsonl, .geojsons, and .ndjson. Some tools also use .json. The format is sometimes called NDJSON-GeoJSON.

Can I open a GeoJSON Sequences file in QGIS?

Yes — QGIS recognises the .geojsonl extension natively. You can also use the Add Vector Layer dialog and select the GeoJSONSeq driver manually for other extensions.
