  In this report, we introduce DocXChain, a powerful open-source toolchain for
document parsing, which is designed and developed to automatically convert the
rich information embodied in unstructured documents, such as text, tables and
charts, into structured representations that are readable and manipulable by
machines. Specifically, basic capabilities, including text detection, text
recognition, table structure recognition and layout analysis, are provided.
Upon these basic capabilities, we also build a set of fully functional
pipelines for document parsing, i.e., general text reading, table parsing, and
document structurization, to drive various applications related to documents in
real-world scenarios. Moreover, DocXChain is concise, modularized and flexible,
such that it can be readily integrated with existing tools, libraries or models
(such as LangChain and ChatGPT), to construct more powerful systems that can
accomplish more complicated and challenging tasks. The code of DocXChain is
publicly available
