Extract text from HeuristicLab storage files (HL)
To convert HL storage files to another format, you need HeuristicLab or other Data software.
To convert other file formats to the "Evolutionary Algorithm Data" file type, you need software like HeuristicLab or a similar tool.
The .HL file functions as a HeuristicLab Storage file, utilized by the open-source HeuristicLab software environment. This framework is designed for prototyping and testing evolutionary and heuristic optimization algorithms. The file securely stores optimization problems, statistical experiment runs, and user-defined algorithmic "workbenches."
Developed by the Heuristic and Evolutionary Algorithms Laboratory (HEAL), the software allows researchers to model complex algorithms visually. However, this creates a major data lock-in. .HL files are deeply proprietary .NET serialized object graphs. Newer versions (3.3.16 and above) rely heavily on binary Protocol Buffers, making the files completely opaque and unreadable to standard text editors or external data science tools like Python or R.
Users typically need to convert .HL data to share experiment results with colleagues or to publish academic findings. The best conversion targets for tabular analytical results are standard CSV or XLSX files. For genetic programming trees, mathematical models are best exported to MATLAB (.MAT) or LaTeX (.TEX). Unfortunately, standard online converters fundamentally fail to process .HL files because they lack the highly specific .NET deserialization libraries required to parse HeuristicLab's custom application logic. Our advanced analyzer can inspect the internal XML or binary structures, bypass the proprietary container limits, and safely extract embedded text strings, configuration parameters, and structural metadata without requiring a complex local software installation.
Convert.Guru analyzes your HL file, detects the exact format, and lets you read the text inside.
Users also converted PDF, L, KL and DL files.
If you want to convert HL file to L, KL, DL, CSV, JSON, XML, YAML, YML, TOML, INI, CFG or CONF, you can use HeuristicLab or similar software from the "Algorithm and Experiment Storage" 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 HL, try HeuristicLab or another comparable tool in the "Algorithm and Experiment Storage" 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 HL converter.
