Convert H2O to another file type
To convert H2O Data files to another format, you need Battle Realms or other Game software.
Convert a file to H2O
To convert other file formats to the "Game Data Archive" file type, you need software like Battle Realms or a similar tool.
About H2O files
A .h2o file is primarily a proprietary game data archive created by Liquid Entertainment for video games like Battle Realms. In an entirely different context, the .h2o extension is also used as an AutoML model leaderboard file by the H2O.ai machine learning platform, as a temperature controller profile by Watlow, and as a master project file for Innovyze H2OMAP. Because of this fragmentation, a .h2o file can contain anything from compiled 3D models and game audio to complex machine learning algorithms and industrial sensor configurations. The major disadvantage of the .h2o format is its highly proprietary nature. These files are not supported by web browsers, standard text editors, or universal archive tools like ZIP extractors. They lock users into specific ecosystems. If you need to access the assets inside a Battle Realms archive, you cannot simply extract them; the files are heavily compiled and obfuscated. Similarly, an H2O.ai leaderboard file requires an active subscription or a properly configured Python/R environment to read. Standard online converters inevitably fail to process .h2o files because they lack the specific reverse-engineered unpacking algorithms or the proprietary data schemas needed to read the data correctly. If our system detects a recognizable internal structure, viewing or partial conversion may still be possible.
Convert.Guru analyzes your H2O file, detects the exact format, and lets you read the text inside.
If you want to convert H2O file to PSI, BAR, PA, CSV, JSON, XML, YAML, YML, TOML, INI, CFG or CONF, you can use Battle Realms or similar software from the "Game Data Archive" 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 H2O, try Battle Realms or another comparable tool in the "Game Data Archive" category.
The H2O 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 H2O converter.
