Extract text from GOLD Parser tables (CGT)
To convert CGT tables to another format, you need GOLD Parser Builder or other Developer software.
To convert other file formats to the "Parser Grammar Rules" file type, you need software like GOLD Parser Builder or a similar tool.
The .CGT file format primarily functions as a Compiled Grammar Table used by the GOLD Parser System. Developers use this format to store deterministic finite automata (DFA) and LALR parse tables generated from grammar rules. Alternatively, .CGT files operate as compressed surveying project data files for C&G Software Systems, compressed templates for Graphisoft, or report templates within IBM Cognos Analytics.
The main disadvantage of the .CGT format is its highly proprietary and fragmented nature. A .CGT file from GOLD Parser is a compiled binary, meaning you cannot read or edit it in standard text editors. You must use the original builder software to decompile it. Conversely, .CGT files used in surveying or by Cognos Analytics are often standard ZIP archives renamed to prevent user tampering. This locks the internal data away from native operating system viewers, requiring specialized software or expensive subscriptions to open.
To overcome these limitations, developers often need to convert .CGT files to open standards like XML or TXT for syntax review. If the file is a disguised archive, users need to extract the raw CSV coordinate data or underlying XML templates. Standard online converters fail to process .CGT files because the extension shares multiple, incompatible technical structures.
Just drag and drop your file into convert.guru to see what it is and convert it if supported. Our analysis engine inspects the binary signature of the file. If we detect a supported embedded format - such as an underlying ZIP archive for survey data - we can bypass the proprietary wrapper, display the internal text or directory structure, and allow you to extract the raw data.
Convert.Guru analyzes your CGT file, detects the exact format, and lets you read the text inside.
Users also converted CTG, TPS, FRM and DDD files.
If you want to convert CGT file to , you can use GOLD Parser Builder or similar software from the "Grammar Table & Survey Data" category. In the File menu, look for Save As… or Export….
To convert files to CGT, try GOLD Parser Builder or another comparable tool in the "Grammar Table & Survey Data" 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 CGT converter.
