Extract text from NMEA 2000 data files (N2K)
To convert N2K data files to another format, you need Maretron N2KView or other Data software.
To convert other file formats to the "Marine Telemetry File" file type, you need software like Maretron N2KView or a similar tool.
The .N2K file format is a specialized data log containing telemetry and configuration data from NMEA 2000 marine networks. It records raw Controller Area Network (CAN bus) traffic, capturing real-time parameters like GPS coordinates, engine RPM, fuel flow, and wind speed from various vessel sensors.
You typically need proprietary marine navigation software such as Maretron N2KView or Coastal Explorer to read these logs natively.
This format presents significant disadvantages for data analysis. Because .N2K files store data in raw CAN frames and hexadecimal Parameter Group Numbers (PGNs), they are completely unreadable in standard text editors. You cannot natively import this data into database tools or spreadsheets to track fuel efficiency or map navigational routes. Furthermore, parsing the binary payloads requires complex decoding libraries, locking your data inside niche maritime software.
Converting .N2K to CSV, JSON, or XML is the best solution for extracting the telemetry. A CSV conversion flattens the hierarchical PGNs into columns, making it easy to analyze the vessel's performance in Microsoft Excel. Keep in mind that some proprietary vendor-specific PGNs might not be fully decoded during conversion and could be omitted.
Due to the strict encoding of NMEA 2000 protocols, standard online converters often fail to identify or translate the raw network frames. Our platform can inspect the underlying data structures of your .N2K files, extract embedded text, and help you convert supported PGNs into universal formats.
Convert.Guru analyzes your N2K file, detects the exact format, and lets you read the text inside.
Users also converted EHI, RDT and SVB files.
If you want to convert N2K file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Maretron N2KView or similar software from the "Marine Telemetry Data Storage" 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 N2K, try Maretron N2KView or another comparable tool in the "Marine Telemetry Data Storage" category.
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 N2K converter.
