NMEA format is supported in Google Earth client at least in the Desktop version.

Go to File > Open, choose your data file, and press “Open.”

If you want to drag/drop file onto Google Earth try renaming it to have a .log extension.

You can find details for importing data from GPS devices in this related Google Earth help article:

The $GPGGA, for example, provides the essential fix data with 3D location and accuracy.

$GPGGA,123804.000,3217.2462,N,03451.8365,E,1,10,0.9,46.7,M,17.5,M,,0000*60

where:
    GGA          Code for GPS Fix Data
