What is a JSS file

JSS files mostly belong to Microsoft Office Word. JSS files may use one of two internal formats. In many cases the file acts as a compressed archive that holds a Word web archive. This archive is created using the ZIP format and bundles content like HTML or XML, which is processed by Microsoft Office Word.
In other cases the file may be built as a PDF document. Such files follow PDF structure and are usually opened with Adobe Acrobat Reader.
Key details compiled by FilExt.com:
  • ZIP Archive: The file packages a Word web archive as a compressed container. Open it with Word or a file decompression tool to inspect its contents.
  • PDF Format: The file is a PDF document. Open it with a PDF reader.
  • JavaScript Style Sheet: Some sources label it as a JavaScript Style Sheet. Verify the file’s structure if it does not open as expected.
  • FilExt.com tip: Use file properties or a magic-number tool to decide which format your JSS file uses.

    How can I open a JSS file?

    You need a suitable software like Microsoft Office Word to open a JSS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your JSS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a JSS file directly in the browser:. Just drag the file onto this browser window and drop it.
