KML to CSV: Export Placemark Data and Coordinates Safely
Learn what a KML-to-CSV export preserves, how geometry becomes table rows, and how to avoid coordinate and attribute mistakes.
KML to CSV conversion turns each Placemark into a spreadsheet row. A useful export includes the name, geometry type, longitude, latitude, altitude, description, ExtendedData, and—when needed—the complete coordinate sequence. CSV is excellent for attribute analysis but cannot preserve KML styles, folders, tours, or 3D assets.
Core Concepts & Learning Progression
Inspect the Placemark model
Understand names, descriptions, geometry, and ExtendedData before flattening a KML layer.
Choose useful columns
Export explicit longitude, latitude, altitude, geometry type, and a full coordinate field.
Handle lines and polygons
Keep the complete coordinate sequence instead of reducing non-point features to one location.
Open and verify
Use UTF-8 CSV in Excel, Google Sheets, pandas, or a GIS table workflow and retain the original KML.
Essential Technical Definitions
Placemark
A KML feature containing a name, description, geometry, and optional attributes.
ExtendedData
Custom KML fields that can be flattened into additional CSV columns.
Geometry type
The Point, LineString, Polygon, or MultiGeometry category represented by a feature.
Coordinate sequence
The complete longitude, latitude, altitude text for a line or polygon geometry.
