CSV to KML Converter

Google Earth and many GIS tools use KML for geographic data. This converter reads CSV rows with coordinate columns and generates KML placemarks — one per row — that you can open directly in Google Earth.

About the CSV with latitude and longitude columns to KML format

Each row with valid latitude and longitude values becomes a KML Placemark. The name column (or first column) becomes the placemark name. Other columns are included in the description. The output is a valid KML document with a Document wrapper.

Common use cases

  • Visualizing store locations from a spreadsheet in Google Earth.
  • Creating a KML tour from a CSV list of heritage sites with coordinates.
  • Plotting field survey points from a CSV onto a map for a project report.
  • Generating delivery route placemarks from a CSV address list with geocoded coordinates.

How to use this tool

  1. Upload your CSV with latitude and longitude columns file or paste the source content into the text box on this page.
  2. Click the convert button and wait for the browser to parse the input into consistent columns.
  3. Inspect the output preview — check row counts, column headers, and sample values before downloading.
  4. Download the result as KML and continue with your spreadsheet, database, or reporting workflow.

Tips for best results

  • Include a 'name' column for meaningful placemark labels in Google Earth.
  • Coordinates must be in decimal degrees: latitude (-90 to 90) and longitude (-180 to 180).
  • Use KML to CSV for the reverse workflow when extracting data from existing KML files.

Common pitfalls

Rows without valid coordinates are skipped silently. Make sure every row has numeric lat/lon values. Swapped latitude and longitude values place markers in the wrong location.
