Convert HLF to another file type
To convert your HLF file to another format, you need HydraCAD or other Database software.
Convert a file to HLF
To convert other file formats to the "Construction Inventory Database" file type, you need software like HydraCAD or a similar tool.
About HLF files
The .HLF file extension is primarily associated with HydraLIST, a critical component of the HydraCAD and SprinkCAD software suites used for designing fire sprinkler systems. These files function as stocklists, containing detailed databases of pipes, valves, and fittings required for a construction project. Technically, many legacy HLF files are actually Microsoft Jet Databases (the same format used by older MDB Access files), but they are locked behind a proprietary extension. Users often struggle to open these files because standard spreadsheet tools like Microsoft Excel do not recognize the extension, making the vital inventory data inaccessible without the original CAD software.
A secondary use for the extension is by Hach analytical instruments (such as the ML600), which generate .HLF files as XML-based data logs containing photometric measurement readings.
To make these files useful outside of their specialized engineering environments, conversion is essential. For HydraCAD stocklists, the best target format is XLSX or CSV, allowing project managers to edit inventory lists in Excel. For archiving or sharing with clients who lack CAD software, converting to PDF is ideal. Hach data logs should be converted to XML (for parsing) or CSV to analyze the raw instrument data.
Convert.Guru analyzes your HLF file, detects the exact format, and lets you read the text inside.
If you want to convert HLF file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use HydraCAD or similar software from the "Fire Sprinkler Stocklist" 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 HLF, try HydraCAD or another comparable tool in the "Fire Sprinkler Stocklist" category.
The HLF 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 HLF converter.
