What is a JAM file?

A JAM file is a CAD file created in the Jam Standard Test and Programming Language (STAPL) format, a standard file format used for programming PLDs (Programmable Logic Devices). It includes the data and algorithm needed to program a PLD. JAM files enable vendor-specific programming requirements to be communicated to PLD programmers in a recognized format.

FigJam Board

A JAM file may also be a board created by the team-collaboration Figma app to organize ideas. It is saved in the proprietary FigJam (FIG) format, storing design elements that make up the whiteboard or diagram, including text, shapes, icons, images, sticky notes, and tables. Figma users save their boards as JAM files to preserve their ideas and then share them with other Figma users or export them to other formats, such as .JPG images or .PDF documents.

Figma is a two-pronged collaborative tool that provides the following workspaces:

Most users access Figma online in their web browsers, but they can also use the desktop app on Windows and macOS (an iOS version was available but is now discontinued). When creating a whiteboard in the FigJam workspace, you can add various design elements to organize and diagram your plans, ideas, etc., then save it to your online account or as a JAM file on your computer.

To save a JAM file with Figma in a web browser or desktop app, click the Figma icon in the upper-left corner and select File → Save local copy (the web browser automatically downloads the JAM file). You can also save your design to the version history associated with your online account by selecting Save to version history instead of Save local copy .

You can open a JAM file with Figma in a web browser or the Windows or macOS desktop app. For example, you can open a JAM file with the desktop version of Figma by selecting the Home icon in the upper-left corner and then clicking Import in the upper-right corner.

Figma can convert JAM files to various file types, including the following formats:

To convert a JAM file in Figma's FigJam workspace, click the app icon in the upper-left corner, then select File → Export as .

JAM Musical Score

Musical score saved in a human-readable, text-based format; represents notes and chords using text descriptions, such as "G7," "Bdim," and "Fmaj7."

JAM files can be played back in Pyva.net JAM using instrument voices from a software synthesizer. The data can also be output to a MIDI device. Since JAM files are text-based, they can be edited with a text editor.

JAM files can be used to play back audio samples, but do not contain actual audio data.
