KML is a vector GIS format, so it isn't always the format the next tool expects. Converting it to CSV lets you open the attributes in Excel or a spreadsheet without redrawing or re-collecting anything. Because GISConverter runs a full GDAL engine in your browser, the geometry and attributes carry across faithfully, and the file never leaves your device.
KML (.kml): KML is the XML-based format Google Earth and Google Maps use to describe points, lines, polygons, labels and styling. Because it is plain text it is easy to read, edit and share, and it stores coordinates in WGS84 longitude/latitude by default.
CSV (.csv): CSV is the universal spreadsheet exchange format: rows of plain-text values that open in Excel, Google Sheets or any text editor. For mapping, a CSV becomes spatial when it carries coordinate columns — typically latitude/longitude, or an X/Y pair — that a GIS can turn into points.
