Convert HW to another file type
To convert HW Data files to another format, you need Lutron HomeWorks or other Data software.
Convert a file to HW
To convert other file formats to the "Proprietary Data & Project File" file type, you need software like Lutron HomeWorks or a similar tool.
About HW files
The .HW file extension is most commonly associated with two distinct proprietary formats: an Electrochemical Experiment Data file generated by H&W elektrochemie, or a Lighting Control System Project file utilized by Lutron HomeWorks. Both formats store highly specific, machine-readable data designed to operate exclusively within their respective hardware and software ecosystems.
Working with .HW files presents significant challenges for everyday users. H&W electrochemical data is locked inside a closed binary structure, meaning you cannot natively open or analyze the data in standard spreadsheet applications like Microsoft Excel or Google Sheets without the original laboratory software. Similarly, Lutron HomeWorks QS project files are proprietary archives tied to expensive residential lighting systems. This restricts technicians from easily reviewing project configurations on unauthorized devices.
To bypass these limitations, you need specific workarounds. For Lutron .HW files, the best conversion target is ZIP, because the file is essentially a disguised archive. By extracting it, you can access the underlying XML setting files. For electrochemical data, exporting the telemetry to CSV or TXT is the only way to preserve the raw data points for external analysis.
Because these files lack open specifications, standard online converters consistently fail to process them. Often, only the original software can properly read or export the specific formatting. However, you can drag and drop your .HW file into convert.guru to instantly identify the format. If our analysis detects the embedded ZIP structure of a Lutron project, viewing or extracting the internal contents may still be possible.
Convert.Guru analyzes your HW file, detects the exact format, and lets you read the text inside.
If you want to convert HW file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Lutron HomeWorks or similar software from the "Hardware Configuration & Data 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 HW, try Lutron HomeWorks or another comparable tool in the "Hardware Configuration & Data Storage" category.
The HW 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 HW converter.
