XLS
SVG files
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.
SVG (Scalable Vector Graphics) is an XML-based vector image format. SVG files store graphics as scalable and editable shapes. They are ideal for web graphics and illustrations, allowing for resizing without loss of quality.
