Turn CSV tables with coordinates into a KML file that opens in Google Earth. 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 KML. The file is processed locally, so your data is never uploaded to a server.
03
The KML file downloads straight to your device. Need another format? Pick a converter below.

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. KML is built for viewing and sharing in Google Earth.
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.
KML
KML (Keyhole Markup Language) is an XML format created for Google Earth and adopted as an OGC standard in 2008. It stores placemarks, paths and polygons together with their styles and descriptions.
KML is the easiest way to show geographic data to people who don't use GIS software, but it is built for display rather than analysis.
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 KML output
KML only supports WGS84, so coordinates are written as longitude/latitude.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Let clients and colleagues explore CSV data in Google Earth — no GIS skills needed.
Import the file into Google My Maps to annotate it and share a link.
Turn CSV data into a clear, styled visual for meetings and reports.
Every converter runs in your browser and keeps your files on your device.
