Extract text from LHS files
To convert your LHS file to another format, you need GHC or other Developer software.
To convert other file formats to the "Source Code" file type, you need software like GHC or a similar tool.
The .LHS format serves a unique niche in the programming world as a Literate Haskell Script. Unlike standard source code that prioritizes machine instructions, .LHS files treat the code as secondary to the explanation, allowing developers to interweave executable Haskell logic with extensive formatting like LaTeX or Markdown. While this is brilliant for academic papers and self-documenting algorithms, it is a common problem in standard development workflows. Most Integrated Development Environments (IDEs) and syntax highlighters struggle to parse the mix of prose and code correctly, and sharing these files with non-Haskell users requires them to install specific tooling like GHC.
To make the content accessible or executable in broader environments, users typically need to convert .LHS files based on their immediate goal. For pure development and compilation, converting to standard HS (Haskell Source) is essential to strip away the formatting layer. Conversely, to publish the documentation aspect for reading, converting to PDF, HTML, or MD (Markdown) using tools like Pandoc is the standard workflow. In rare legacy cases (approx. 9%), an .LHS file may be associated with older Microsoft Jet Database implementations, though this is often a confusion with LDB lock files. If your file is not readable text, it is likely a binary database artifact.
Convert.Guru analyzes your LHS file, detects the exact format, and lets you read the text inside.
Users also converted HS, CS and LSP files.
If you want to convert LHS file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use GHC or similar software from the "Literate Programming Source Code" 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 LHS, try GHC or another comparable tool in the "Literate Programming Source Code" 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 LHS converter.
