Extract text from Heart rate data files (HRM)
To convert HRM Heart rate files to another format, you need Polar Flow or other Data software.
To convert other file formats to the "Device Sensor Data" file type, you need software like Polar Flow or a similar tool.
The .HRM file is primarily a Heart Rate Monitor data file generated by Polar fitness tracking devices. These files store workout telemetry, including heart rate, speed, altitude, and cadence over time. A secondary use for .HRM files is industrial power measurement, specifically as power quality harmonics data files generated by HIOKI Power Quality Analyzers. Finally, a small percentage are musical analysis data files used by the Humdrum Toolkit or Harmony Assistant.
Users manage fitness-based .HRM files via Polar Flow or older legacy software like Polar ProTrainer. Industrial users require the proprietary HIOKI 9624-50 application to process electrical measurement data.
The primary disadvantage of the .HRM format is its proprietary nature. Modern fitness platforms like Strava or Garmin Connect do not natively support .HRM uploads. Industrial HIOKI files suffer from extreme vendor lock-in, requiring a paid software license just to view basic harmonics data.
For fitness data, you must convert .HRM to universal standards like TCX, FIT, or GPX to maintain GPS and heart rate synchronization. For industrial data analysis, exporting to CSV is the best approach to ensure compatibility with standard spreadsheet tools.
Because these files are highly specific to the hardware that created them, they are difficult to open or convert. Often, only the original proprietary software can properly read or export the exact telemetry data. We can identify the file format, inspect the internal headers, and show raw text content. If our analysis detects a supported embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your HRM file, detects the exact format, and lets you read the text inside.
Users also converted ATP, DYN and MTB files.
If you want to convert HRM file to , you can use Polar Flow or similar software from the "Fitness and Heart Rate Tracking" category. In the File menu, look for Save As… or Export….
To convert files to HRM, try Polar Flow or another comparable tool in the "Fitness and Heart Rate Tracking" 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 HRM converter.
