Extract text from Ruby documents (RDOC)
To convert RDOC documents to another format, you need Ruby or other Developer software.
To convert other file formats to the "Documentation Markup File" file type, you need software like Ruby or a similar tool.
A .rdoc file is a Ruby Document file used primarily to store source code documentation and readme files for projects written in the Ruby programming language. Developers write these files using a specific markup syntax, which the Ruby rdoc tool processes to generate formatted HTML. You can open and edit these files using plain text editors like Visual Studio Code or Sublime Text.
However, for general users, the .rdoc format presents significant disadvantages. It operates much like a closed, proprietary format for anyone outside the Ruby developer ecosystem. Standard web browsers cannot render it, and document readers will only show raw text mixed with confusing markup symbols. It requires specific development environments to display correctly.
Because of these limitations, users often need to convert .rdoc files to HTML for web viewing, MD (Markdown) for modern repository compatibility, or PDF for sharing. Standard online converters frequently fail to process this file because they lack the highly specialized parser required to understand the unique RDoc syntax. Even if full syntax rendering fails, we can extract the underlying text so you can read the content without installing Ruby developer tools.
Convert.Guru analyzes your RDOC file, detects the exact format, and lets you read the text inside.
If you want to convert RDOC file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Ruby or similar software from the "Source Code Documentation" 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 RDOC, try Ruby or another comparable tool in the "Source Code Documentation" 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 RDOC converter.
