Turn CSV tables with coordinates into a Shapefile that opens in any desktop GIS. Free, private and processed right in your browser.
Three steps, no software to install. Works on Windows, macOS, Linux and mobile.
01
Drop a .csv file with coordinate columns into the converter, or click to browse. Files up to 100 MB are supported.
02
Click Convert to Shapefile. The file is processed locally, so your data is never uploaded to a server.
03
The Shapefile file downloads straight to your device. Need another format? Pick a converter below.
Converted your CSV file? Upload it to GISCARTA and turn it into an interactive map your team or clients can actually use.
Colour by attribute, cluster thousands of points, switch on 3D.
Charts and key numbers next to the map, updated as you filter.
Animate dated features and compare how places change.
Publish a read-only map, embed it on your site, or keep it private with role-based access.
No credit card. No GIS degree. Upload your data and start mapping in minutes.
CSV is built for spreadsheets, databases and BI tools. Shapefile is built for exchange with ArcGIS and other desktop GIS.
CSV
CSV (comma-separated values) is plain text where each line is a row and commas separate the columns. Location is stored in coordinate columns, such as latitude and longitude, or as WKT geometry text.
Every spreadsheet, database and BI tool reads CSV, which makes it the universal hand-off format. It has no data types, styles or coordinate system metadata.
Shapefile
The Shapefile is Esri's vector format from the early 1990s. One dataset is a set of files — .shp (geometry), .shx (index), .dbf (attributes) and .prj (coordinate system) — usually shared as a .zip.
It is still the most widely supported GIS format, but it has hard limits: one geometry type per file, field names of up to 10 characters and a 2 GB size cap.
Your CSV file
The CSV needs coordinate columns (latitude/longitude or X/Y) or a WKT geometry column, so every row can be placed on the map.
The Shapefile output
Shapefile field names are limited to 10 characters, so longer names are shortened, and each file holds a single geometry type.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Hand over CSV data in the format every ArcGIS and QGIS user can open.
Many government agencies and clients still ask for Shapefile deliverables — send CSV data the way they expect.
Use the CSV data in geoprocessing tools and older workflows built around Shapefiles.
Every converter runs in your browser and keeps your files on your device.
