Extract text from LCM files
To convert your LCM file to another format, you need Lowrance MapCreate or other GIS software.
To convert other file formats to the "Chartplotter Map Container" file type, you need software like Lowrance MapCreate or a similar tool.
The .LCM extension is shared by several disparate technical ecosystems, creating significant confusion for users. The most common variation is the Lowrance Chart Map file, a proprietary vector format used by Lowrance marine chartplotters to store navigation data like contour lines, waypoints, and shorelines. These files are optimized for embedded hardware, making them difficult to view or edit on a standard PC without discontinued software like MapCreate. Users often struggle to migrate this data to modern mapping tools or Google Earth because the format does not natively support standard interchange formats like GPX or KML.
In scientific environments, .LCM files serve as Liquid Chromatography Method files generated by software such as SCIEX Analyst or Shimadzu LabSolutions. These contain critical instrument parameters for chemical analysis. The friction here is licensing: opening an .LCM file usually requires a workstation with a specialized, expensive license key. Scientists often need to convert these parameters to PDF for archival compliance or TXT for peer review. Additionally, in robotics, .LCM stands for Lightweight Communications and Marshalling, a set of libraries for message passing. These log files are binary dumps of robot sensor data; developers almost always need to convert them to CSV or MAT (MATLAB) to analyze the data meaningfully.
Convert.Guru analyzes your LCM file, detects the exact format, and lets you read the text inside.
Users also converted LCD, LMC, LCPL, ZIP, PDF, TRA, AGS, LSF, BCM and HCF files.
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.
