Convert KMZ to CSV

Understanding KMZ and CSV file formats

KMZ is a compressed file format used by Google Earth and other mapping applications to store geographic data, including placemarks, paths, and overlays. It is essentially a zipped version of a KML (Keyhole Markup Language) file, often containing additional resources like images.

CSV (Comma-Separated Values) is a simple text-based format for storing tabular data, where each line represents a row and columns are separated by commas. CSV files are widely used for data exchange, especially in spreadsheets and databases.

Why convert KMZ to CSV?

Converting a KMZ file to CSV allows you to extract geographic coordinates and attribute data into a tabular format. This is useful for data analysis, importing into GIS software, or working with mapping data in spreadsheet applications like Microsoft Excel or Google Sheets.

How to convert KMZ to CSV

To convert a KMZ file to CSV, you need to extract the KML file from the KMZ archive and then transform the geographic data into a table. Here are the steps:

1. Rename your .kmz file to .zip and extract it to access the .kml file inside.
2. Use a conversion tool or GIS software to convert the .kml file to .csv.

Best software and tools for KMZ to CSV conversion

• QGIS (Free and open-source):
  Layer → Add Layer → Add Vector Layer to import the KML, then Layer → Export → Save Features As... and choose CSV as the format.
• Google Earth Pro (Free):
  Open the KMZ, right-click the layer, select Save Place As... and choose KML. Then use an online converter or GIS tool to convert KML to CSV.
• Online converters (e.g., MyGeodata Converter, GPS Visualizer):
  Upload your KMZ file and select CSV as the output format.

Tips for successful conversion

• Check the structure of your KML/KMZ file to ensure placemarks and coordinates are properly formatted.
• After conversion, review the CSV file to verify that all relevant data (latitude, longitude, names, descriptions) has been correctly extracted.
