Excel workbooks (.xlsx, and legacy .xls) are where most location lists start life — customer lists, store addresses, site inventories and survey results. For mapping, each row is one place with latitude and longitude columns plus any attributes you want to keep. Converting between Excel and GIS formats lets you send a spreadsheet to Google Earth or GIS software, or pull mapped data back into a workbook for reporting.
Need the other direction instead? KMZ is a zipped, self-contained KML — the Google Earth delivery format. KMZ is simply a KML file (plus any referenced icons or overlays) compressed into a single ZIP archive with a .kmz extension. It's the format Google Earth produces when you save a place, because bundling everything into one compact file makes maps easy to email and share. Under the hood it's still KML, so a KMZ converts cleanly to and from every other geographic format.
Excel files are read from the first worksheet, and each row needs latitude/longitude columns (or a WKT geometry column). On export, points get longitude/latitude columns and lines or polygons are written to a geometry column as WKT.
