Convert LCM to another file type
To convert LCM Data files to another format, you need Lowrance MapCreate or other Data software.
Convert a file to LCM
To convert other file formats to the "Proprietary Equipment Data" file type, you need software like Lowrance MapCreate or a similar tool.
About LCM files
The .LCM file extension is plagued by format collision, meaning it serves entirely different purposes depending on its origin. Primarily, it functions as a Chartplotter Map Data file used by Lowrance marine electronics for underwater navigation and GPS mapping. Alternatively, it is a Liquid Chromatography Method file utilized by high-end laboratory software like Shimadzu LabSolutions or SCIEX Analyst. Less commonly, it stores laser cutting parameters for Friendess CypCut, robotics logs for Lightweight Communications and Marshaling (LCM), or game camera data for Capcom MT Framework. The primary disadvantage of .LCM files is their strict, proprietary nature. Lowrance map files are locked to specific GPS hardware ecosystems and cannot be natively opened by web browsers or standard GIS tools. Similarly, chromatography method files require expensive, specialized lab software subscriptions to simply view experiment parameters. This creates massive bottlenecks when sharing data with peers, moving routes to mobile phones, or archiving scientific results. To solve these interoperability problems, conversion is mandatory. For marine navigation, convert to GPX or KML to utilize your routes and waypoints in standard mapping applications like Google Earth. For laboratory data, export or convert to CSV for analysis in standard spreadsheets or .PDF/A for immutable archiving.
Convert.Guru analyzes your LCM file, detects the exact format, and lets you read the text inside.
If you want to convert LCM file to BCM, HCF, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF or DAT, you can use Lowrance MapCreate or similar software from the "Chartplotter Map & Lab Data" 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 LCM, try Lowrance MapCreate or another comparable tool in the "Chartplotter Map & Lab Data" category.
The LCM 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 LCM converter.
