Extract text from JAWS script files (JSS)
To convert JSS scripts to another format, you need Microsoft Word or other Developer software.
To convert other file formats to the "Script or Archive" file type, you need software like Microsoft Word or a similar tool.
A .jss file can represent several entirely different data formats, making it a confusing and frustrating file to handle. Commonly, a .jss file is actually a misnamed Word Open XML archive (DOCX) or a secured PDF used by the Strata J-ICE viewer. In developer and accessibility circles, it functions as either a JavaScript Style Sheet - a discontinued Netscape technology - or a custom macro script for the JAWS screen reader. Video editors may also recognize it as a JACOsub Subtitle File.
Opening these files depends entirely on their true internal structure. You can view text-based developer scripts in code editors like Visual Studio Code, open Open XML variants in Microsoft Word, or read secured documents with Adobe Acrobat Reader. The primary disadvantage of the .jss extension is this extreme ambiguity. A secured PDF limits your accessibility and heavily restricts data portability. JavaScript Style Sheets are entirely obsolete for modern web design, requiring a complete rewrite. JAWS scripts are proprietary code that is useless outside their specific accessibility ecosystem.
To make these files usable, you must convert them based on their content. Web scripts should be migrated to modern CSS or JS. JACOsub files must be exported to universally supported SRT or VTT subtitles. If the file is a disguised document, extracting it to DOCX or standard PDF is strictly required to read it on modern devices.
Standard online converters constantly fail with .jss files because they rely blindly on the file extension, which offers no guarantee of the internal format. Drag and drop your file into convert.guru to identify the format, view its text or binary structure, and convert it if supported. Our deep-file analysis detects the true underlying signature (like a ZIP container or PDF header), enabling a pragmatic workaround for this highly inconsistent file type.
Use Convert.Guru to open and convert your JSS file.
Users also converted MP4, CFB, LZ, HZF and CSS files.
If you want to convert JSS file to CSS, MP4, AVI, MOV, WMV, FLV, WEBM, MKV, M4V, 3GP, OGV or ASF, you can use Microsoft Word or similar software from the "Styling, Subtitles, or Archives" category. In the File menu, look for Save As… or Export….
To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to JSS, try Microsoft Word or another comparable tool in the "Styling, Subtitles, or Archives" 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 JSS converter.
