About NTM files

The .ntm file is a mobile network cell data log generated by network monitoring applications like Netmonitor or CellMapper. It stores raw logs of cell tower locations, signal strengths (RSRP, RSRQ), network types (4G, 5G), and GPS coordinates collected by mobile devices. Users primarily open these files within the original Android apps or upload them to the CellMapper web platform to crowdsource cellular coverage maps. The .ntm format is highly specialized and closed. It is not natively supported by standard spreadsheet software or GIS platforms. You cannot easily read the data in Excel or QGIS without parsing the proprietary structure. Furthermore, the format can vary between different app versions, meaning your data is locked into specific tools. The best conversion targets for geospatial analysis are CSV for tabular data analysis in Microsoft Excel, KML for visualization in Google Earth, or GeoJSON for web mapping. Note that custom app-specific metadata might be lost during conversion to standard tables. This file format is difficult to open or convert because it is a proprietary, non-standardized database or binary log. Often, only the original software can properly read or export the data. Just drag and drop your file to see what it is and convert it if supported. Convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.

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

Users also converted VTX, EBK and NXS files.

The NTM 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 NTM converter.
