Extract text from AutoLISP scripts (LSP)
To convert LSP scripts to another format, you need Autodesk AutoCAD or other Developer software.
To convert other file formats to the "CAD Automation Script" file type, you need software like Autodesk AutoCAD or a similar tool.
The .LSP file extension is primarily an AutoLISP Source Code File used by Autodesk AutoCAD and its derivatives. These files contain macros and routines written in the Lisp programming language to automate repetitive design tasks, draw custom geometric shapes, or calculate architectural measurements within the CAD environment. Less commonly, .LSP files function as racing game physics data (Milestone WRC series), printer layout setups for combit List & Label, or Leica Cyclone 3D point cloud data.
Because an .LSP file is typically plain text, opening it requires a code editor or the original CAD software. The main disadvantage is that non-engineers and clients cannot read or review the code logic easily. Executing the script visually requires an expensive AutoCAD license. Furthermore, if the file is a protected or compiled AutoLISP script (similar to FAS or VLX files), it cannot be read as text at all and becomes proprietary binary data.
To share the script for review or printing, convert .LSP to TXT or PDF. For archiving code snippets or adding comments, convert it to DOCX. Drop your file here to view and convert it securely right in your browser - free, online, and without installing heavy CAD software.
Convert.Guru analyzes your LSP file, detects the exact format, and lets you read the text inside.
Users also converted LISP, VLX, ISP, FAS, TXT, LLSP, PDF, LCPL, MPP, DWG, ZIP, PLP and DOCX files.
If you want to convert LSP file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Autodesk AutoCAD or similar software from the "AutoLISP Source Code Script" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to LSP, try Autodesk AutoCAD or another comparable tool in the "AutoLISP Source Code Script" 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 LSP converter.
