Convert CSV to SHP
Turn CSV / delimited text into Shapefile (zipped) instantly in your browser. No upload, no account, and no file ever crosses the network.
About CSV / delimited text
Delimited table with lon/lat columns, a WKT geometry column, or both.
- With lon/lat output, non-point geometries are written as their centroid.
About Shapefile (zipped)
Real .shp/.shx/.dbf/.prj/.cpg written in the browser, packaged as a ZIP.
- Field names are truncated to 10 characters and text values to 254 bytes (DBF limits).
- Mixed geometry types are split into one shapefile layer per type.
Step by step
How to convert CSV to SHP
- 01
Drop your .csv file
Open the converter and drop the CSV / delimited text 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.
CSV to SHP — questions
Is converting CSV to SHP really private?
Yes. The conversion runs entirely in your browser using a Web Worker — the CSV / delimited text file is never sent to a server, so it works with confidential data and offline.
Do I need an account to convert CSV 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.
