pyhwp
hwp file format parser
Decision gist · record as of 2026-08-14
Yes, with conditions. Install if you need to parse or extract data from HWP files and can tolerate beta-status software and high install friction. The package is actively maintained, has no known vulnerabilities, and fills a niche need for HWP document handling. However, be aware that the last release was in 2020, the experimental conversion features may not be production-ready, and AGPLv3+ licensing imposes copyleft obligations on derivative works.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires cryptography, lxml, and olefile as runtime dependencies; source distribution requires build tools; Python 2.7 or 3.5+ support declared but package is in beta.
- High install friction due to source distribution and no runtime dependencies listed in metadata.
- Package is actively maintained with recent commits, but last release was in 2020; requires --pre flag for installation due to beta versioning.

What it is and what it does
pyhwp is a parser and processor for HWP (Hancom Word Processor) Document Format v5 files, the native format used by Korean word processing software. It allows you to read HWP files, analyze their internal structure, and extract embedded streams and content. The package includes experimental features for converting HWP documents to OpenDocument (.odt) or plain text (.txt) formats, making it useful for document analysis, format conversion, and content extraction workflows.
The package depends on cryptography, lxml, and olefile for its core functionality. It is actively maintained and supports multiple Python implementations (CPython, Jython, PyPy) across Python 2.7 and 3.5–3.8. However, it is distributed as a source tarball and remains in beta status, requiring the --pre flag during installation.
Use it for
- Extract text and metadata from HWP documents for indexing or archival purposes
- Convert HWP files to OpenDocument format for compatibility with other office suites
- Analyze the internal structure and streams of HWP files for forensic or research purposes
- Batch process Korean word processor documents in automated workflows
- Migrate legacy HWP documents to open formats for long-term preservation
