Shapefile vs CSV: GIS Format vs Tabular Data
Shapefile stores rich vector geometry (points, lines, polygons) with attributes. CSV stores rows and columns of data — it can represent point geometry using latitude and longitude columns but cannot store line or polygon geometry.

Bottom line
Use Shapefile for any spatial analysis involving non-point geometry. Use CSV when exchanging point data with non-GIS tools like Excel, databases, or data science workflows.
Shapefile vs CSV: feature comparison
| Feature | Shapefile | CSV |
|---|---|---|
| Geometry support | Points, lines, polygons | Points only (via lat/lon columns) |
| Human readable | No (binary .shp) | Yes (plain text) |
| Opens in Excel | No | Yes |
| GIS analysis ready | Yes | Requires import/parsing |
| File size | Compact binary | Text (larger for same data) |
| CRS metadata | Yes (.prj file) | No (must be known) |
ShapefileWhen to use Shapefile
- Any geometry beyond simple points
- Spatial analysis workflows requiring topology
- Sharing with GIS professionals
CSVWhen to use CSV
- Point datasets shared with non-GIS users
- Integration with databases, Excel, or data science tools
- Quick data exchange where geometry is just lat/lon

Frequently asked questions
Q.Can CSV store polygon data?
Not directly. CSV can store geometry as WKT in a column, but standard GIS tools expect lat/lon point columns. For polygons, use GeoJSON, Shapefile, or GeoPackage.
Q.How do I convert Shapefile to CSV with coordinates?
Maparz converts Shapefile to CSV. For point geometries, the output includes latitude and longitude columns. For line/polygon geometries, Maparz exports geometry as WKT.
