Extract text from LISP files
To convert your LISP file to another format, you need GNU Emacs or other Developer software.
To convert other file formats to the "Source Code Script" file type, you need software like GNU Emacs or a similar tool.
A .LISP file is primarily a source code script written in the Lisp (List Processing) programming language, historically favored for artificial intelligence research and complex symbolic computation. These are plain text files that define functions, macros, and lists enclosed in parentheses. While powerful, the format presents significant friction for non-developers: raw .LISP files depend on specific environments like GNU Emacs or LispWorks to execute, and they lack native formatting for easy reading on standard devices. Furthermore, sending a raw code file to a client or manager often results in confusion or software compatibility errors.
To share logic or documentation without requiring the recipient to install a compiler, users frequently convert .LISP files to PDF for fixed-layout archiving and printing. For web documentation, converting to HTML preserves basic structure, while RTF allows for inclusion in word processing workflows like Microsoft Word.
Critical Security Warning: If your personal documents, images, or videos have suddenly been renamed with a .lisp extension and cannot be opened, you are likely a victim of the STOP/Djvu ransomware. In this specific scenario, the file is not a valid code script but an encrypted hostage file; standard file converters cannot decrypt or recover this data.
Convert.Guru analyzes your LISP file, detects the exact format, and lets you read the text inside.
Users also converted LSP, VLX, LLSP, TXT, FAS, DWG, SHX, VBA, PYTHON and JAVA files.
If you want to convert LISP file to FAS, VBA, PYTHON, VLX, JAVA, JS, TS, PY, CPP, C, CS or PHP, you can use GNU Emacs or similar software from the "Lisp Programming Source Code" 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 LISP, try GNU Emacs or another comparable tool in the "Lisp Programming Source Code" 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 LISP converter.
