About SUD files
The .SUD file format is heavily fragmented and serves multiple distinct purposes. Most often, it functions as an internal data file for ERP systems developed by GFI Informatique. It is also widely used as a CAD reinforcement steel schedule in Nemetschek Allplan, a professional 3D design software. Other systems use .SUD files to store visual novel game scripts for the Makura engine, LISAM indexed databases by SHARC Informatique, or simple text-based Sudoku puzzles.
The primary disadvantage of .SUD files is their proprietary and closed nature. If a structural engineer sends you an Allplan .SUD schedule, you cannot open it without a specialized, expensive CAD license. These files are not supported by standard web browsers, document viewers, or basic spreadsheet software.
Users typically need to convert .SUD CAD schedules to standard formats like CSV, XLSX, or PDF to share material lists with contractors and fabricators. However, standard online converters fail to process them. This is because .SUD files lack a single public standard, and the binary data structures of an ERP database or an Allplan schedule are completely undocumented.
Because this file format is difficult to open or convert, often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your SUD file, detects the exact format, and lets you read the text inside.
If you want to convert SUD file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Allplan or similar software from the "ERP and CAD System Data" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to SUD, try Allplan or another comparable tool in the "ERP and CAD System Data" category.
The SUD Converter Story
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 SUD converter.
