Extract text from LEX files
To convert your LEX file to another format, you need Microsoft Word or other Developer software.
To convert other file formats to the "Source Code & Data" file type, you need software like Microsoft Word or a similar tool.
The .LEX extension primarily refers to two distinct file types: Lexical Analyzer Source files used by developers and Dictionary Data files used by Microsoft software.
For developers, a .LEX file contains logic definitions for generating lexical analyzers using tools like flex or the original Unix Lex. These files are plain text but require compilation into C or C++ code to be executable. The challenge is that without the specific compiler environment, the file is just a script that cannot be run directly. Converting these to PDF creates sharable documentation of the code logic, while converting to TXT ensures they open in any basic editor without syntax errors.
For general users, .LEX files often function as proofing tools or User-Defined Dictionaries for Microsoft Office and Windows IME (Input Method Editor). These contain custom words, spelling patterns, or language rules. These files are frequently proprietary or binary-encoded, meaning they cannot simply be double-clicked to view the contents. Users typically need to extract the word lists to standard formats.

If you want to convert LEX file to SYS, DLL, EXE, DRV, VXD, 386, COM, BAT, CMD, SCR, PIF or LNK, you can use Microsoft Word or similar software from the "Lexical Analysis & Spelling Dictionaries" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to LEX, try Microsoft Word or another comparable tool in the "Lexical Analysis & Spelling Dictionaries" 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 LEX converter.
