Extract text from CLS files
To convert your CLS file to another format, you need Visual Basic or other Developer software.
To convert other file formats to the "Source Code File" file type, you need software like Visual Basic or a similar tool.
The .CLS file extension primarily represents a Class Module or Class Definition file used across several programming and typesetting environments. The most common variation is the VBA Class Module used by Microsoft Office applications (Excel, Access) to store object-oriented logic. Other significant uses include Salesforce Apex source code and LaTeX document layout definitions.
While these files are essential for developers and typesetters, they present significant friction for general users. Opening a .CLS file often requires installing heavy Integrated Development Environments (IDEs) like Visual Studio or navigating command-line interfaces. Users frequently encounter these files when extracting macros, auditing code, or managing academic templates, only to find they cannot view the contents without specific software. Furthermore, sending a raw code file to a client or colleague often results in formatting errors or compatibility warnings. For quick auditing or viewing without an IDE, convert .CLS to TXT. If you need to share code documentation, print layouts, or archive project structures, converting to PDF ensures the formatting remains intact and secure. For web documentation, converting source code to HTML preserves structure for browser viewing.
Convert.Guru analyzes your CLS file, detects the exact format, and lets you read the text inside.
Users also converted XLS, CSL, CSV, PDF, BST, ZIP, CLC, PNG, XLSX, DOCX, TEX, TSX and XML files.
If you want to convert CLS file to XLS, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO or RS, you can use Visual Basic or similar software from the "Source Code Class Definition" 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 CLS, try Visual Basic or another comparable tool in the "Source Code Class Definition" 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 CLS converter.
