How to Convert Excel to KMZ: A Step-by-Step Guide

Converting Excel to KMZ is a process where you take spreadsheet data and turn it into a file that can be viewed on mapping software like Google Earth. To do this, you’ll need to ensure your Excel file is properly formatted, convert it to a CSV file, then use a conversion tool or software to create the KMZ file.

After completing the conversion, you’ll be able to import the KMZ file into mapping software, where it will display the spreadsheet data as placemarks on the globe. This is particularly useful for visualizing geographic data or creating interactive maps.


Ever had a bunch of data in an Excel spreadsheet that you wished you could visualize on a map? Well, that’s where converting Excel to KMZ comes in handy. KMZ is a file format used by Google Earth and other mapping software to display geographic data on a 3D globe. It’s ideal for anyone working with location data, whether you’re a scientist tracking animal migrations, a market analyst looking at store locations, or a travel enthusiast mapping out your next adventure.

Now, you might be wondering why we would want to convert an Excel file into a KMZ file. The answer is simple: visualization. Excel is great for organizing and analyzing data, but when it comes to presenting that data in a way that’s easy to understand and visually appealing, a map can’t be beaten. Plus, with a KMZ file, you can add layers, styles, and other elements that make your data come to life.

So, whether you’re a professional needing to share geographic data with colleagues or a student presenting a project, learning how to convert Excel to KMZ is a skill that can elevate your data game. Let’s dive into the step-by-step tutorial on how to make that happen.

Step by Step Tutorial on How to Convert Excel to KMZ

Before you start the conversion process, make sure your Excel file is prepped and ready. This means your location data should include columns for latitude and longitude coordinates. Once that’s set, here’s a simple guide to take you through the conversion:

Step 1: Save the Excel file as a CSV

The first step is to save your Excel spreadsheet as a CSV (Comma Separated Values) file. This format is compatible with many conversion tools and is necessary for creating a KMZ file.

Saving your Excel file as a CSV is straightforward. Just click on ‘File’, navigate to ‘Save As’, and choose CSV from the dropdown menu. Make sure all your data is properly organized in columns, with the first row containing headers for each column.

Step 2: Use a Conversion Tool

Now, it’s time to convert that CSV file into a KMZ file. There are various online tools and software available for this purpose, like ‘CSV to KML Converter’ or ‘Earth Point’.

Choosing the right conversion tool can make a difference. Look for one that’s user-friendly and offers options for customizing how your data will appear on the map. Once you’ve selected a tool, upload your CSV file, follow the instructions provided, and download your new KMZ file.

Step 3: Open the KMZ File in Google Earth

Finally, open Google Earth or any other compatible mapping software, navigate to ‘File’, and click on ‘Open’. Select your KMZ file, and voilà! Your Excel data is now beautifully plotted on the globe.

Opening your KMZ file in Google Earth should be a seamless experience. It gives you a chance to see your data in a whole new light and share it with others. You can even add additional information to each placemark, like images or descriptions, for a more interactive map.


Enhanced VisualizationConverting Excel to KMZ allows you to see your data represented visually on a map, which can make it easier to identify trends, patterns, and outliers.
ShareabilityKMZ files can be easily shared with others, making it simpler to collaborate on geographic data projects.
Interactive MapsWith KMZ files, you can create interactive maps that include additional information, images, and styles, providing a richer experience for viewers.


Potential for Data LossIn the conversion process, there’s a risk of losing some data or formatting, especially if the Excel file is not set up correctly.
Limited EditingOnce in KMZ format, it’s harder to make changes to the data compared to when it’s in Excel.
Software DependencyYou need access to mapping software like Google Earth to view KMZ files, which may not be readily available to everyone.

Additional Information

Converting Excel to KMZ can be a game-changer for anyone dealing with geographic data. However, it’s important to keep a few key points in mind. First, ensure your latitude and longitude data is accurate; even small errors can result in misplaced placemarks. Also, be mindful of privacy concerns; if your data includes sensitive information, consider how sharing a KMZ file might impact privacy.

Remember, KMZ is just one of many geographic data formats; depending on your needs, you might find others like GPX or KML more suitable. Lastly, don’t forget to back up your original Excel file before starting the conversion process. You never know when you might need to revert or reference the original data.


  1. Save the Excel file as a CSV.
