Extract text from Court transcripts (SGNGL)
To convert SGNGL transcripts to another format, you need Case CATalyst or other Data software.
To convert other file formats to the "Computer-Aided Transcription File" file type, you need software like Case CATalyst or a similar tool.
A .SGNGL file is a proprietary Court Transcript file, specifically categorized as Case CATalyst Text Data. It is actively used by court reporters and transcriptionists to store stenographic session data, including highly formatted text, timestamps, speaker labels, and hidden synchronization markers.
These files are natively managed and generated by Stenograph Case CATalyst software, though related platforms like StenoCAT32 occasionally interact with similar outputs.
Because .SGNGL is a closed, proprietary format, it is notoriously restrictive. You cannot simply open an .SGNGL file on a standard Mac or Windows machine. Viewing the original document requires an active, expensive subscription to specialized court reporting software. If a paralegal, client, or attorney receives this file extension, they are entirely blocked from reading the legal transcript.
To make the transcript accessible, users must convert the .SGNGL file into standard formats like RTF (specifically RTF/CRE - Court Reporter Extension), PDF, or DOCX. While the core text is preserved during conversion, proprietary stenographic metadata - such as raw keystroke mappings or embedded audio sync markers - will usually be lost or ignored.
Standard online converters fail to process .SGNGL files because the internal file structure and formatting logic remain unpublished and tightly controlled by the developer. Often, only the original software can properly read or export the structured data. If our analysis detects readable text blocks wrapped within the code, viewing or partial text extraction may still be possible.
Convert.Guru analyzes your SGNGL file, detects the exact format, and lets you read the text inside.

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 SGNGL converter.
