Extract text from WLS files
To convert your WLS file to another format, you need Wolfram Mathematica or other Data software.
To convert other file formats to the "Scientific Measurement Data" file type, you need software like Wolfram Mathematica or a similar tool.
The .WLS extension is shared by three distinct but technical file types, creating frequent confusion for users. The most common modern usage is for Wolfram Language Scripts, which are executable text files containing code for Wolfram Mathematica. While powerful for computational tasks, these scripts require the Wolfram Engine to run and are not natively readable by standard text editors without proper formatting. Users often need to convert these to PDF for documentation or NB (Notebook) for interactive editing.
In scientific environments, .WLS files store Spectrophotometer Wavelength Data generated by instruments from manufacturers like Scinco or Shanghai SUZIL. These files contain critical spectral measurements (wavelength vs. absorbance) often locked in proprietary binary or legacy text formats compatible only with software like UVWinLab or M.Wave Professional. Researchers frequently encounter compatibility barriers when trying to analyze this data in modern tools like Microsoft Excel. Converting these files to CSV or XLSX is essential for data portability and graphing.
Finally, legacy .WLS files may be spreadsheets from the obsolete 602Tab suite or Microsoft Works. These archaic formats are generally unsupported by modern office suites, requiring conversion to XLSX or ODS to recover the historical financial or tabular data inside.
Convert.Guru analyzes your WLS file, detects the exact format, and lets you read the text inside.
Users also converted DOCUMENT FROM BS, QUA, TXT, INP, FP3, PDO, MP4, SLDPRT, JPG, AAE, BIN and CRDOWNLOAD files.
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 WLS converter.
