Convert GMS to another file type
To convert GMS macros and models to another format, you need CorelDRAW or other Developer software.
Convert a file to GMS
To convert other file formats to the "Macro Script File" file type, you need software like CorelDRAW or a similar tool.
About GMS files
A .GMS file is most commonly a macro script used by CorelDRAW to automate repetitive design tasks. These scripts are written in VBA (Visual Basic for Applications) and store recorded actions to save time on complex workflows. Alternatively, a .GMS file functions as source code for the General Algebraic Modeling System (GAMS), containing mathematical optimization models used by economists and engineers. While useful in their native environments, .GMS files are heavily restricted. A CorelDRAW macro is proprietary and requires an expensive, paid license of the Corel suite to execute. It also poses a massive security risk because VBA scripts can easily contain malicious malware payloads. Similarly, GAMS files are plain text but rely on specialized, expensive compilers to run properly. If you need to review the code without installing expensive software or risking your system's security, you must convert the file. For safe code review and web sharing, convert .GMS to TXT or HTML. For documentation, auditing, and archiving, convert to PDF or DOCX. Note that converting a .GMS file extracts the human-readable code but removes its ability to execute within CorelDRAW or GAMS.
Convert.Guru analyzes your GMS file, detects the exact format, and lets you read the text inside.
If you want to convert GMS file to LB, MGS, EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP or MAP, you can use CorelDRAW or similar software from the "Macro Script or Mathematical Model" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to GMS, try CorelDRAW or another comparable tool in the "Macro Script or Mathematical Model" category.
The GMS Converter Story
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 GMS converter.
