Extract text from Visual Basic source files (BAS)
To convert BAS source files to another format, you need Visual Studio or other Developer software.
To convert other file formats to the "Source Code File" file type, you need software like Visual Studio or a similar tool.
A .BAS file is a source code module written in the BASIC programming language or Visual Basic. These files contain routines, macros, and variables used to automate tasks in Microsoft Office applications via Visual Basic for Applications (VBA), or act as code modules in classic Visual Studio projects.
You can open standard plain-text .BAS files with any text editor, such as Notepad++. Legacy tokenized files require old DOS emulators running QBasic or GW-BASIC. Learn more about the history of the language on the Visual Basic Wikipedia page.
The biggest disadvantage of .BAS files is their security risk. Email clients and web browsers aggressively block them because they can contain malicious, system-level macros. Furthermore, older GW-BASIC files are "tokenized" - saved as compressed binary data. If you open a tokenized .BAS file in a modern text editor, you will only see garbled, unreadable text.
To bypass email filters and safely share the code, convert .BAS to TXT. For documentation or code archiving, convert to .PDF/A. If you have an old tokenized file, you need to extract the raw text.
Convert.Guru analyzes your BAS file, detects the exact format, and lets you read the text inside.
Users also converted VBA, TXT, VBP, B, DOCX, PDF, XLSM, FRM, PNG, ZIP, XLSX, RAR and MP3 files.
If you want to convert BAS file to EXE, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO or RS, you can use Visual Studio or similar software from the "Source Code Storage" 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 BAS, try Visual Studio or another comparable tool in the "Source Code Storage" 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 BAS converter.
