Abstract: Common text editors such as Microsoft Word, Notepad++ and others are cumbersome. Despite their enormous functionality, they do not eliminate the risk of incorrectly converting the document, for example, when opening the same Word files on older or, conversely, newer versions of Microsoft Word. The way out is the use of markup languages, which allow you to mark up text blocks in order to present them in the desired style. Currently, very popular are LaTeX (a set of macro-extensions of the TeX typesetting system) and Markdown (a lightweight markup language, designed to denote formatting in plain text). So the question of converting a Markdown document into a LaTeX document is relevant. There are various tools to convert Markdown files to LaTeX document, such as Pandoc library, Markdown.lua, Lunamark and others. But most of them have redundant steps to generate the output document. This paper highlights a solution method by integrating a Markdown file into a LaTeX document, which will potentially reduce the output document generation time unlike existing solutions. The developed Markdown to LaTeX document converter will automatically generate the output document and reduce the possibility of errors when manually converting text from Markdown format to LaTeX format.
