Extract text from KOMPAS-3D & SigmaPlot files (SPW)
To convert SPW files to another format, you need KOMPAS-3D or other Cad software.
To convert other file formats to the "Specification File" file type, you need software like KOMPAS-3D or a similar tool.
The .SPW file extension is most commonly associated with KOMPAS-3D, a popular engineering CAD system developed by ASCON. It functions as a specification document that lists parts, assemblies, and materials for a 3D model. Structurally, modern KOMPAS-3D .SPW files are often simply renamed ZIP archives containing XML data and related resources. Additionally, the .SPW format can represent a SigmaPlot Worksheet used by Systat Software for graphing scientific data, or a legacy audio file from older video games.
The primary disadvantage of .SPW files is their strict software dependency. You cannot open a KOMPAS-3D specification file natively in widespread CAD tools like AutoCAD or SolidWorks. It requires installing the proprietary KOMPAS-3D viewer or the full CAD suite, which requires a paid license and is rarely installed outside of specific engineering teams. Similarly, for the SigmaPlot variant, data is locked behind specialized graphing software, making it difficult to share raw numerical data with colleagues using Excel or Python.
To bypass these limitations, convert your .SPW file based on your final goal. For sharing engineering specifications with non-CAD users, convert the .SPW to PDF to lock the layout and text formats for printing and archiving. If you need to edit the tabular data, extract or convert the specification into XLSX or CSV. If dealing with a SigmaPlot worksheet, converting to CSV ensures maximum cross-platform compatibility. Drop your file here to analyze and convert it securely right in your browser, without needing to buy a heavy CAD license.
Convert.Guru analyzes your SPW file, detects the exact format, and lets you read the text inside.
Users also converted CDW, SPV, PLAN, FRW, BAK, SWP, SPF, SIG, ZIP, DMP, MCDX, LBL and XMCD files.
If you want to convert SPW file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use KOMPAS-3D or similar software from the "CAD Specification Document" 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 SPW, try KOMPAS-3D or another comparable tool in the "CAD Specification Document" 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 SPW converter.
