Convert XLMX to XML

Understanding xlmx and xml file formats

XLMS is not a standard file extension. If you meant XLMX, it is likely a typo or a proprietary spreadsheet format. However, the most common spreadsheet formats are XLSX (Microsoft Excel Open XML Spreadsheet) and XLSM (Excel Macro-Enabled Workbook). For the purpose of this article, we will assume you are referring to XLSX files.

XML (eXtensible Markup Language) is a widely-used markup language for storing and transporting data in a structured, human-readable format. Converting spreadsheet data to XML is useful for data exchange, integration, and web applications.
