An XLSM file is a macro spreadsheet created by Microsoft Excel, a spreadsheet program that comes with every edition of the Microsoft Office suite. Cell worksheets arranged in rows and columns as well as built-in macros programmed in the Visual Basic for Applications (VBA) language. All XLSM files are saved in the Open XML format introduced in Microsoft Office 2007.
A WEBP file is an image recorded in the WebP format (Quote; Weppy & Quote; Sharp & Quote;) in the Matrix image format developed by Google for Web graphics. The WebP reduces the size of the file more than the standard JPEG compression while maintaining a similar or better image quality. It supports both lossless and lossless compression and includes an alpha channel for transparency, similar to .PNG.
