Extract text from HRL files
To convert your HRL file to another format, you need Relive or other Data software.
To convert other file formats to the "Fitness Log / System Log" file type, you need software like Relive or a similar tool.
The .hrl extension generally refers to one of two distinct formats that cause very different user frustrations. Most commonly, it is a Heart Rate Log or Compressed Erlang Trace Log, often associated with fitness tracking applications like Relive or specific Erlang/OTP debugging workflows. These files are typically GZIP compressed, making them unreadable to standard text editors. Users often need to convert them into universally accepted fitness formats like GPX (GPS Exchange Format) or TCX to upload workout data to platforms like Strava or Garmin Connect.
Alternatively, in enterprise environments, an .hrl file is a Hyper-V Replica Log generated by Microsoft Windows Server. These files track changes between virtual machine replications and are notorious for "bloating" storage - sometimes growing to terabytes in size if replication fails. Unlike fitness logs, Hyper-V HRL files are binary system files that cannot be "converted" in the traditional sense; they must be merged or deleted via the Hyper-V Manager to reclaim disk space. Less frequently, .hrl files are standard Erlang Header Files containing plain text macro definitions, which can be edited in any IDE like Visual Studio Code.
Convert.Guru analyzes your HRL file, detects the exact format, and lets you read the text inside.
Users also converted HAR, PDF, VBM, VHDX and MRT files.
If you want to convert HRL file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Relive or similar software from the "Fitness Data & System Logging" 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 HRL, try Relive or another comparable tool in the "Fitness Data & System Logging" 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 HRL converter.
