About NB files
The .NB file extension represents a notebook document created by Wolfram Mathematica, a premier system for modern technical computing. These files are distinct from standard scripts because they combine executable code, real-time calculation results, high-resolution graphics, and formatted text into a single interactive environment. While this format is powerful for research and education, it presents a significant barrier to sharing: opening an .NB file requires the proprietary Mathematica software or the large Wolfram Player installation. Without these specific tools, the file - though technically text-based - appears as a chaotic stream of internal syntax and cell expressions. To ensure your research is accessible to collaborators or readable on standard devices, conversion is often necessary. Converting .NB to PDF creates a universally viewable static document ideal for printing and archiving. For web publishing, converting to HTML preserves the structure for browsers. Academic authors frequently convert notebooks to LaTeX for journal submissions, while developers may strip the metadata to save pure code as WL or M files.
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.
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.
