About

Excel

Microsoft Excel format (.xlsx and .xls) is the most commonly used spreadsheet format. Similar to CSV, coordinate columns in Excel files can be used to create geographic features. XLSX is the modern Office Open XML format, and XLS is the traditional binary format. Excel format offers advantages over CSV including multiple worksheets, data type validation, and formatting.

KML

KML (Keyhole Markup Language) is an XML-based geographic markup language originally developed by Keyhole and later acquired by Google, becoming an OGC standard. KML can describe points, lines, polygons, image overlays, 3D models, and other rich geographic content. It is the native format for Google Earth and Google Maps. KML files organize geographic data using tags and attributes, and support style definitions and network link functionality.

Conversion trade-offs

Excel: limitations to know

  • Binary format, larger file size than CSV
  • Requires specialized libraries for parsing, not as universal as CSV

KML: what you gain

  • Deep integration with Google ecosystem, can be displayed directly in Google Earth
  • Supports NetworkLink for dynamic data updates

Why convert Excel to KML?

Converting Excel to KML is one of the most common workflows in GIS. Excel data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while KML is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your Excel files, keeps geometry and attributes intact, and writes clean KML output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the Excel to KML converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting Excel to KML?

By default the output keeps the source coordinate system. If your Excel file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.

Can I convert multiple files at once?

Yes — drop several Excel files at once and each one produces its own KML output.
