Convert NB to another file type
To convert NB notebooks to another format, you need Wolfram Mathematica or other Data software.
Convert a file to NB
To convert other file formats to the "Computational Notebook" file type, you need software like Wolfram Mathematica or a similar tool.
About NB files
The .NB file extension is a structured text document used primarily as a Wolfram Mathematica Notebook. These files contain a mix of executable computer code, mathematical formulas, formatted text, and interactive graphics. They are widely used by researchers, physicists, and data scientists using Wolfram Mathematica. The major disadvantage of the .NB format is its highly proprietary nature. Opening, executing, and editing these files natively requires an active, expensive software license. While a free Wolfram Player is available, it restricts editing and deep interaction. Furthermore, raw .NB files are not supported by web browsers and look like a confusing, nested string of code if opened in a standard text editor. To share your mathematical models or research with non-technical stakeholders, you must convert the file. For universal reading and archiving, convert .NB to .PDF. This locks the visual layout and complex math typography into a readable format, though interactivity is lost. For web publishing, convert to .HTML. If you only need to extract the raw programming logic, convert to .TXT or .WL (Wolfram Language). Drag and drop your file here to analyze and convert it - free, online, and without installing heavy software.
Convert.Guru analyzes your NB file, detects the exact format, and lets you read the text inside.
Users also converted PDF, IPYNB, ZIP, DOCUMENT FROM VIRAJ, TXT, NP, MA, ND, MB, JPG, ICHATDOCKTILE, DM4 and SDOCX files.
FAQ
If you want to convert NB file to PDF, GB, OD, DN, IPYNB, XLS, XLSX, XLSM, XLSB, ODS, CSV or TSV, you can use Wolfram Mathematica or similar software from the "Interactive Computational Document Storage" category. In the File menu, look for Save As… or Export….
To convert WQ1, XLSM, NOTES, QPW, WK3, WB2, WKS, XLSB, 123, XLS, WB1 or XLSX files to NB, try Wolfram Mathematica or another comparable tool in the "Interactive Computational Document Storage" category.
The NB 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 NB converter.
