Convert a file to JNB

To convert other file formats to the "Scientific Graphing Notebook" file type, you need software like SigmaPlot or a similar tool.


About JNB files

A .JNB file is a proprietary notebook format created by SigmaPlot, a specialized software suite used for advanced scientific graphing and statistical analysis. These files act as comprehensive containers - structured using the Microsoft Compound File format - that store raw data worksheets, statistical report results, and high-resolution 2D/3D graphs in a single location.

While .JNB files are powerful for research, they present significant accessibility barriers. Because the format is strictly proprietary and binary, it cannot be opened by standard office tools like Microsoft Excel or text editors. This creates "vendor lock-in," making it difficult to share findings with colleagues who do not possess an expensive SigmaPlot license. Furthermore, the format is not web-friendly or suitable for direct submission to academic journals. To resolve this, users should convert the underlying data to XLSX or CSV for analysis in other tools, and convert the graphs to PDF, EPS (for vector-based print quality), or PNG (for web presentation).

Convert.Guru analyzes your JNB file, detects the exact format, and lets you read the text inside.

Users also converted PNG, JPG, IPYNB, APKG, SAV, NBP, PYTHON and LIFE files.
