Extract text from C/C++ header files (H)
To convert H header files to another format, you need Visual Studio Code or other Developer software.
To convert other file formats to the "Source Code Header" file type, you need software like Visual Studio Code or a similar tool.
A .h file is a plain text source file used as a header in the C, C++, and Objective-C programming languages. It primarily contains function prototypes, data type definitions, and macro definitions designed to be shared across multiple source files. You can open and edit these files in Integrated Development Environments (IDEs) like Microsoft Visual Studio or advanced text editors like Notepad++. You can learn more about the C++ programming language on Wikipedia.
Despite being standard in software development, .h files present several real-world challenges for non-developers. They are raw source code and cannot be executed directly; they must be included in a main program and processed by a compiler. Without a dedicated code editor, they lack syntax highlighting, making them difficult to read or audit. Furthermore, sharing raw .h files with clients, project managers, or legal teams often leads to confusion or accidental formatting changes if they attempt to open the code in standard word processors.
To solve these issues, converting your .h file is often necessary. For official documentation, legal auditing, or cross-team code review, convert .h to PDF. This locks in the code structure and preserves formatting for anyone reading it. For web publishing or documentation wikis, convert it to HTML. If you simply need universal sharing without requiring the recipient to have an IDE installed, convert it to standard TXT. Drag and drop your file to analyze and convert it - free, online, and without installing software right here on convert.guru.
Convert.Guru analyzes your H file, detects the exact format, and lets you read the text inside.
Users also converted CPP, HEADER, INO, C, HPDF, TXT, VCXPROJ, HEIC, ZIP, BIN, SO, TTF and JPG files.
If you want to convert H file to S, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO or RS, you can use Visual Studio Code or similar software from the "C/C++ Source Header" 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 H, try Visual Studio Code or another comparable tool in the "C/C++ Source Header" 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 H converter.
