What is a .sgml file?

A .sgml file is a Standard Generalized Markup Language. This is a code, script or executable format.

How to open a .sgml file

  • VS Code opens and highlights nearly every text-based code format.
  • Never run a script you didn't write or trust.

The registry records this extension against Standard Generalized Markup Language, so software from that family is the most likely match.

How to convert a .sgml file

  • Text-based code needs no conversion โ€” just save with a different extension if a tool insists.

MIME type

When a .sgml file travels over the web, servers label it with this MIME type:

text/sgml
