Extract text from Construction and genealogy files (GW)
To convert GW Data files to another format, you need Glodon Cubicost or other Data software.
To convert other file formats to the "Cost Estimation Project" file type, you need software like Glodon Cubicost or a similar tool.
A .gw file is most commonly a Construction Project Data file generated by Glodon software (e.g., Cubicost), widely used in the Asian construction industry for cost estimation, bill of quantities (BOQ), and tendering. These files are proprietary and deeply integrated into the Glodon ecosystem, functioning similarly to a locked project container. Users often struggle to open them without an active, region-specific Glodon license, making data portability a major friction point. The format is sometimes technically described as a SEP2__SUREXML document, hinting at an underlying XML structure wrapped in a binary container.
Alternatively, a .gw file may be a GeneWeb Source File, a plain-text format used by the open-source genealogy software GeneWeb. Unlike the Glodon format, these are human-readable text files containing family trees, individual records, and relationships. Users typically need to convert these to the standard GED (GEDCOM) format to migrate their family history data to modern platforms like Ancestry or MacFamilyTree.
Convert.Guru analyzes your GW file, detects the exact format, and lets you read the text inside.
Users also converted MW, TWH, W, TW and PJ files.
If you want to convert GW file to MW, TWH, W, TW or PJ, you can use Glodon Cubicost or similar software from the "Construction Project Data" category. In the File menu, look for Save As… or Export….
To convert files to GW, try Glodon Cubicost or another comparable tool in the "Construction Project Data" 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 GW converter.
