The JNB (SigmaPlot) File Format

jnb file format

When a person decides to devote his or her life to science, graphs become an unavoidable part of life. Whether it’s for a website, book publishing, or a scientific paper, the ability to quickly create readable graphs is essential.

These days, nobody uses pen and paper anymore. Instead, scientists rely on graphing software, such as SigmaPlot and its JNB file format. Let’s go over what the JNB file format is, how you can open it, and how you can recover or repair it after a hard drive crash or malware infection.

What Is a JNB File?

The .JNB file format is the main file format used by SigmaPlot, a popular graphing software developed by Systat Software Inc. SigmaPlot is a Windows-only application, originally developed by Jandel Corporation for Windows 3.1x. The current version supports all versions of the Windows operating system from Windows 2000 to the most recent one.

Files with the JNB file extension contain all data the software needs to generate graphs and perform sophisticated data analysis. Some of the main features of SigmaPlot include global curve fitting, standard curves micro, statistical analysis, advisory statistical analysis, automatic updating of quick transforms, and others.

How to Open JNB Files?

To open files with the JNB file extension, you will need a copy of SigmaPlot. There are currently two ways how you can obtain one. You can either download the fully-functional 30-day trial version from the official website, or you can purchase the commercial edition of SigmaPlot.

The free trial version is fully functional for 30 full days, so you can evaluate the software and decide whether it’s worth its price. Keep in mind that the free trial version is offered for evaluation purposes only. Users are prohibited from using the graphs generated by the free trial version for commercial purposes. A full commercial license costs $899.

Alternatively, you can use Origin, another popular graphing software. Origin is developed by OriginLab Corporation for Microsoft Windows. It includes various 2D/3D plot types as well as the ability to import various file formats, including JNB, Excel, NI TDM, DIADem, DAT, QDA, Mat, SIE, SAV, SPC, and CGM, just to name a few.

How to Recover Deleted JNB Files?

JNB data recovery is no laughing matter. Many students, researchers, and engineers rely on the software on a daily basis, often using it to perform data analysis that will determine the outcome of multi-million dollar projects. Even though scientists are used to making regular backups of the data they’re working with, accidents still happen.

Disk Drill and other similar data recovery applications can rescue deleted or corrupted JNB files – as well as over 200 other file formats – with just a few clicks. Compared to SigmaPlot or Origin, the cost of even the most expensive version of Disk Drill is negligible.

How to Repair JNB Files?

Thanks to its extra free disk tools, Disk Drill protects your data from corruption, helps you create byte-to-byte disk backups, and alerts you in case it detects any potential disk-related issues. The advanced data recovery algorithms it employs to recover deleted JNB files can detect even small chunks of deleted files and recover as much information from them as possible.
