What it is and what it does
ansi2html is a utility for converting terminal text containing ANSI color and formatting codes into HTML or LaTeX markup. It works both as a Python library (via the Ansi2HTMLConverter class) and as a command-line tool, making it useful for capturing colored terminal output and rendering it in web pages or documents. The package depends on importlib-metadata and typing-extensions, both lightweight standard-library backports.
Typical use cases include converting colored log output to HTML for web display, converting task runner output to shareable HTML, or piping colored command output through the tool to preserve formatting. It has been actively maintained since its first release in 2010, supports Python 3.7 through 3.12, and carries no known security vulnerabilities.
Use it for
- Convert colored log files to HTML for web-based log viewing and archival
- Pipe colored CLI tool output through ansi2html to create shareable HTML reports
- Preserve terminal colors when exporting test runner or build tool output to HTML
- Convert colored task management or monitoring tool output to LaTeX for documentation
- Generate HTML versions of colored terminal sessions for documentation or tutorials
