How it Works

01Paste or Upload Your CSV

Paste CSV text or upload a .csv file with geographic point data. Your CSV should have columns for latitude, longitude, name, and any description fields.

02Map Columns to KML Fields

Select which CSV columns correspond to the KML Placemark name, description, latitude, and longitude fields. The converter handles the mapping automatically.

03Preview the KML Output

The tool generates a valid KML document with a Folder element containing one Placemark per CSV row — each with Point coordinates and the mapped properties.

04Download the KML File

Download the .kml file ready to import directly into Google Earth, Google Maps My Maps, ArcGIS, or any KML-compatible mapping application.

What is a CSV to KML Converter?

Data conversion is one of those tasks that should be simple but often isn't — especially when formats have subtle variations, edge cases, and encoding quirks that trip up manual approaches. Our CSV to KML Converter was built to handle these real-world complexities cleanly, giving you accurate, properly formatted output every time without requiring technical expertise or specialized software.

The tool supports all the common variations and configurations you're likely to encounter, with automatic detection of common format quirks and clear error messaging when inputs don't match expected patterns. Whether you're converting a handful of records or a large dataset, the process is the same: paste or upload your input, optionally adjust any settings, and download or copy your converted output.

Built for developers, data analysts, students, and business users alike, this converter prioritizes accuracy and ease of use above everything else. It's completely free, runs in your browser, and never stores your data after processing. Bookmark it — you'll come back to it.

How It Works?

Source Input: Paste your raw data or upload your source file into the input editor for processing.
Validate Data: Our system automatically checks for formatting errors and prepares the data for transformation.
Set Target Format: Choose your desired output format and any specific delimiters or styling requirements.
Export Results: Copy the transformed code directly to your clipboard or download the converted file for immediate use.

The formula

Each CSV row becomes one KML Placemark. Required columns: latitude, longitude (decimal degrees). Optional: name, description, altitude. Multi-geometry types (LineString, Polygon) require ordered coordinate sequences.
Real-World Example

Calculation In Practice

Input CSV: name,lat,lon
"Coffee Shop",40.7128,-74.0060
"Central Park",40.7851,-73.9683

Output KML contains two Placemarks with coordinates and labels ready for Google Earth or GPS devices.

Typical Use Cases

1
Visualizing business locations or survey points in Google Earth
2
Creating GPS waypoint files for field work or navigation devices
3
Converting spreadsheet geographic data into mapping formats
4
Building KML overlays for drone flight planning or delivery zones
