Extract text from CSW files
To convert your CSW file to another format, you need Cary WinUV or other Data software.
To convert other file formats to the "Scientific Data File" file type, you need software like Cary WinUV or a similar tool.
The .CSW extension primarily refers to raw data files generated by Varian Cary UV-Vis-NIR spectrophotometers, instruments widely used in chemistry and physics for analyzing light absorption. These files store spectral scans, typically plotting wavelength against absorbance. The major drawback for researchers is that .CSW is a proprietary binary format tied to the legacy Cary WinUV software suite (now maintained by Agilent). Opening them requires specific, often expensive, instrument control software that may not run on modern operating systems without a physical license dongle. Users generally need to convert these measurements into CSV, XLSX, or plain ASCII text to analyze the data in tools like Microsoft Excel or OriginLab.
A secondary but significant use of the .CSW format is in medical devices, specifically HOFFRICHTER CPAP machines used for sleep apnea therapy. These files log compliance and efficacy data (pressure, leakage, usage hours). Patients often find themselves locked out of their own health data because the required viewing software (like TRENDset) is restricted to clinicians. To view sleep reports or share data with a doctor, converting these proprietary logs to PDF or CSV is the most practical solution.
Other less common variants include workspace files for camLine Cornerstone data analysis software and coordinate system definitions for Trimble geomatics applications.
Convert.Guru analyzes your CSW file, detects the exact format, and lets you read the text inside.
Users also converted CSV, BSW, FDSW and VTK files.
If you want to convert CSW file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use Cary WinUV or similar software from the "Spectroscopy Data Storage" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to CSW, try Cary WinUV or another comparable tool in the "Spectroscopy Data Storage" 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 CSW converter.
