DOCX (Office Open XML document) is a file format used for word processing documents. Introduced by 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.
Excel files, in XLS and XLSX formats, are spreadsheet documents created by Excel. These files are widely used for organizing, analyzing, and presenting data. Excel provides powerful features for data manipulation, formula calculations, and chart creation, making it a versatile tool for business and data analysis.
