gnumex: Excel to LaTeX Integration Tool

This section introduces the gnumex tool. Here I will provide a detailed explanation of gnumex's functionality and applications. gnumex is an open-source software utility designed to integrate Microsoft Excel with LaTeX documents. The tool enables users to create tables in Excel and then directly insert them into LaTeX documents. This significantly simplifies table creation workflow while ensuring consistent formatting and visual alignment with the overall document style. The utility operates through export functions that generate LaTeX-compatible code from Excel spreadsheets, handling formatting conversion and data structure preservation automatically. Additionally, gnumex supports LaTeX macro integration for processing table data, providing enhanced flexibility through programmable data manipulation. This macro support allows users to implement custom formatting rules, mathematical operations, and style adjustments using LaTeX's powerful typesetting capabilities directly within their Excel-originated tables.
