Extract text from SGM files
To convert your SGM file to another format, you need Arbortext_Editor or other Text software.
To convert other file formats to the "Markup Language File" file type, you need software like Arbortext_Editor or a similar tool.
The .SGM extension primarily refers to documents formatted in Standard Generalized Markup Language (SGML), an ISO 8879 standard that serves as the parent technology to both HTML and XML. These files are robust, machine-readable text documents used heavily in government, aerospace, and technical publishing to define complex document structures independent of formatting.
However, .SGM files present significant usability hurdles today. Because SGML is an older, complex metalanguage, modern web browsers (like Chrome or Firefox) do not natively render these files. Opening them usually requires expensive, enterprise-grade publishing software like Arbortext Editor or legacy tools. Users without this software often see raw, cluttered code rather than a readable document.
A secondary but common use for the .SGM extension is as a VisualBoyAdvance savestate. In this context, the file is a binary capture of a Game Boy Advance game's memory (often GZIP compressed), allowing players to resume progress on emulators. These cannot be opened with text editors.

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 SGM converter.
