Convert NMEA to another file type

To convert your NMEA file to another format, you need Google Earth or other GIS software.

Convert a file to NMEA

To convert other file formats to the "GPS Data Log" file type, you need software like Google Earth or a similar tool.


About NMEA files

The .NMEA file type is a plain text data log that stores GPS, GNSS, and marine navigation information using the NMEA 0183 interface standard. Originally developed by the National Marine Electronics Association, this format consists of ASCII "sentences" (e.g., starting with $GPGGA or $GPRMC) that encode real-time position, velocity, and time data from sensors. While universal for hardware communication, the raw text format is notoriously difficult for humans to read and is not natively supported by popular mapping visualization tools like Google Earth or fitness platforms like Strava. To visualize your route on a map, analyze speed in Microsoft Excel, or import tracks into a GPS unit, you typically need to convert .NMEA files to GPX (for compatibility), KML (for 3D mapping), or CSV (for data processing).

Convert.Guru analyzes your NMEA file, detects the exact format, and lets you read the text inside.

Users also converted TXT, LOG, TS, NMA, CSV, MP4, MOV, GPX, JPG, CDW and KML files.


FAQ

If you want to convert NMEA file to GPX, KML, CSV, MP4, JSON, XML, YAML, YML, TOML, INI, CFG or CONF, you can use Google Earth or similar software from the "GPS/GNSS Navigation Logging" category. In the File menu, look for Save As… or Export….

To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to NMEA, try Google Earth or another comparable tool in the "GPS/GNSS Navigation Logging" category.



The NMEA Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NMEA converter.
