Microsoft Excel is a widely used spreadsheet software for data analysis and management. However, when it comes to exchanging data between different systems or applications, a standardized format is often required. XRDML (X-Ray Diffraction Markup Language) is a markup language used to represent X-ray diffraction data. In this paper, we discuss the process of converting Excel files to XRDML with high-quality transformation. We present a step-by-step approach to achieve this conversion, highlighting the challenges and solutions encountered during the process.
