Extract text from LSP files
To convert your LSP file to another format, you need Autodesk AutoCAD or other Developer software.
To convert other file formats to the "Lisp Source Code" file type, you need software like Autodesk AutoCAD or a similar tool.
The .LSP file extension is most frequently associated with AutoLISP, a dialect of the Lisp programming language specifically designed for use within Autodesk AutoCAD. These files contain plain text source code used to automate complex drafting tasks, define custom commands, and streamline CAD workflows. While .LSP files are standard text, they pose specific challenges: they require a compatible CAD environment to execute, and sending raw source code allows recipients to modify or break your scripts. Additionally, standard text editors like Notepad do not provide the necessary syntax highlighting, making code difficult to read or debug. Less common uses include physics definition files for racing games like WRC or printer settings for combit List & Label, which are often proprietary or binary formats that fail to open in text editors entirely.
To share AutoLISP logic without exposing the raw code to edits, or to archive scripts for documentation, converting .LSP to PDF is the ideal solution. For quick viewing on mobile devices or computers without development tools, converting to TXT or RTF ensures universal accessibility. If you are dealing with a game-related .LSP file, generic conversion often results in garbled text; these specific files require modding tools or game-specific extractors.
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 "AutoCAD Automation 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 "AutoCAD Automation 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.
