Format Details
XLS
XLS is the legacy binary spreadsheet format used by Microsoft Excel from 1987 through the Office 2003 era, based on Microsoft's proprietary Binary Interchange File Format (BIFF). It stores worksheets, formulas, charts, and macros in a binary structure that requires Microsoft's format specification to parse correctly. XLS remains common in older enterprise systems and when compatibility with legacy versions of Excel is required.
HTML
HTML (HyperText Markup Language) is the standard markup language for creating web pages and web applications, maintained by the W3C. It defines the structure and content of documents using elements and tags, working alongside CSS for visual styling and JavaScript for interactivity. HTML is rendered by web browsers into the visual pages users see, and is the universal output format for documents published on the internet.
