How to convert GeoJSONL to WKT
- 1
Add your GeoJSONL file
Drag and drop your .geojsonl file onto the box above, or click to browse — you can also paste the raw text directly.
- 2
Convert in your browser
GeoMaps reads the GeoJSONL and rewrites it as WKT locally, on your device. The conversion is instant and your file is never sent anywhere.
- 3
Download your WKT
Click download to save the converted .wkt file, or copy the output text. That's it — no account, no watermark, no limits.
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.
Need the other direction instead? WKT is well-Known Text — the geometry syntax used by spatial databases. WKT (Well-Known Text) is the OGC standard text representation of geometry — POINT, LINESTRING, POLYGON and their multi- variants — used throughout spatial databases like PostGIS, MySQL and SQL Server, and in SQL queries. It describes geometry only, one shape per line, which makes it perfect for pasting features into a database or pulling geometry out of one.
WKT encodes geometry only — feature attributes/properties are not part of the format and are dropped on conversion to WKT.

GeoJSONL to WKT — FAQ
- How do I convert GeoJSONL to WKT?
- Upload your .geojsonl file using the converter above (drag & drop or click to browse). GeoMaps converts it to WKT instantly in your browser and gives you a .wkt file to download. No software to install and no signup required.
- Is the GeoJSONL to WKT 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 WKT back to GeoJSONL?
- Yes. Use our WKT to GeoJSONL converter for the reverse conversion — every format on GeoMaps converts both ways.
- Anything to know about WKT output?
- WKT encodes geometry only — feature attributes/properties are not part of the format and are dropped on conversion to WKT.
- 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.
