Step by step
How to convert NDJSON to SHP
- 01
Drop your .ndjson file
Open the converter and drop the GeoJSON Lines (NDJSON) file — parsing happens locally in a Web Worker, so nothing is uploaded.
- 02
Choose SHP as the output
Pick SHP, reproject to any of 180+ coordinate systems if needed, trim attributes and preview the geometry on a map.
- 03
Download the .zip file
Save a single file, or convert a whole batch and download everything as a ZIP. Nothing is stored after the download.
NDJSON to SHP — questions
Is converting NDJSON to SHP really private?
Yes. The conversion runs entirely in your browser using a Web Worker — the GeoJSON Lines (NDJSON) file is never sent to a server, so it works with confidential data and offline.
Do I need an account to convert NDJSON to SHP?
No. There is no signup, no email and no install. Open the converter, drop the file and download the result.
What happens to attributes and coordinate systems?
Field names are truncated to 10 characters and text values to 254 bytes (DBF limits). You can also reproject between 180+ coordinate reference systems or add a custom proj4 definition before writing.
