What is a .JNB file?
A .JNB file is a type of document called a SigmaPlot Notebook File. It's made using SigmaPlot, which is a special computer program for looking at and making sense of data through pictures like 2D and 3D charts. Inside a .JNB file, you can find data organized in a neat way in tables (which are made up of columns and rows) or shown as graphs. These files also keep details about the graphs, like what they are supposed to represent.
The main software that can open a .JNB file is called SigmaPlot, made by Systat Software. If you see a .JNB file, it's probably because you are working in science or research, or someone who does work in those areas has shared it with you. SigmaPlot is used for making complex data easier to understand by turning it into visual graphs.
If you have a .JNB file but need to share it with someone who doesn't use SigmaPlot, you can change it into a different type of file that more people can open. SigmaPlot lets you save these graphs or data as other file types like .PDF (which is good for documents), .XLSX and .XLS (which are used by Microsoft Excel for spreadsheets), or .CSV (a simple format for data).
It's important to know that the data in a .JNB file might have been typed in by someone, pulled from a database, or brought in from another type of file, like an Excel spreadsheet or a CSV file. This makes .JNB files very flexible for handling different sources of data.
