DOCX
XLS files
DOCX (Office Open XML document) is a file format used for word processing documents. Introduced by Microsoft Word, DOCX files are XML-based and contain text, images, and formatting. They provide improved data integration and support for advanced features compared to the older DOC format.
XLS (Microsoft Excel spreadsheet) is an older file format used for storing spreadsheet data. Although largely replaced by XLSX, XLS files can still be opened and edited in Microsoft Excel. They contain tabular data with formulas, charts, and formatting.
