Extract text from Multisim 9 circuits (MS9)
To convert MS9 circuits to another format, you need NI Multisim or other Cad software.
To convert other file formats to the "Circuit Simulation Schematic" file type, you need software like NI Multisim or a similar tool.
The .ms9 file extension represents a legacy Circuit Design created by National Instruments Multisim (specifically version 9, released circa 2006). These files contain schematic layouts, SPICE simulation models, and virtual instrument settings used by engineers and students to prototype electronic circuits.
The Problem: Because .ms9 files are proprietary containers from a specific era of NI Multisim, they are notoriously difficult to open without the original paid software. A standard text editor may reveal some XML-based headers (leading to the description "Electronics Workbench XML"), but the actual circuit logic and visual schematic are unreadable. Furthermore, free "Multisim Viewers" are virtually non-existent for this specific version, leaving users with old project files they cannot view or print.
The Solution: To make these designs accessible to non-engineers or for web publishing, the standard workflow is converting them to PDF (for documentation) or PNG (for visual sharing). If manufacturing is the goal, the internal data must be exported to Gerber files using the original software.
Convert.Guru analyzes your MS9 file, detects the exact format, and lets you read the text inside.
Users also converted MS8, PRZ and LVM files.
If you want to convert MS9 file to , you can use NI Multisim or similar software from the "Electronic Circuit Design" category. In the File menu, look for Save As… or Export….
To convert files to MS9, try NI Multisim or another comparable tool in the "Electronic Circuit Design" category.
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 MS9 converter.
