OverviewAn XLSX is one of the components of Microsoft’s office suite and it is popularly known as Excel or spreadsheet. It is compatible with Windows, Android and iOS. It stores the data in worksheets and each worksheet comprises of a number of cells (boxes) that are organized in a grid of columns and rows. These cells in actual store the data and every cell has its own identity (numbered row and letter named column). This identification of each cell is used to write formulae and to perform other arithmetical operations. They can also refer to other cells to get the values. The data can be formatted in this the same way, as we do in Microsoft word. It may also contain charts, histograms and line graphs; etc and these can be displayed using three-dimensional graphics. Boxes can be auto-filled by just dragging and expanding the selection box which one wants to copy.
Technical descriptionIt is the successor to XLS as this predecessor only stores data using a single binary file whereas XLSX uses Open XML format in which files and folders are stored separately under a ZIP compression. The graphs that are generated can be attached to the current sheet or can be added to the different sheet. Besides this, there are some add-ins which can be used in Excel sheets. It includes, Analysis ToolPak for Statistical and Engineering data analysis), Analysis ToolPak VBA (Visual basics of the application comes into act here), Euro Currency Tools (To convert and format Euro) and Solver Add-in (for optimization and equation solving).

OverviewAn XML file is a data file that is used to store,send and recreate the arbitrary data.It outlines a set of guidelines for document encoding in such a way that it can be read by both machines and humans.That is is the main reason these files are processed easily. XML files contain dataset that is meant to be used for structuring the data on a website, web application, or computer programme..
Technical descriptionXML follows almost the same syntax as HTML as it has one root element that is the parent of all other elements. It comprises metadata and tags, which are used to structure the data.IETF RFC 7303 (successor of RFC 3023) lays forth guidelines for creating media types that may be used in XML messages. The three media types defined are Application/xml, application/xml-external-parsed-entity, and application/xml-dtd Text/xml is an alias for application/xml. They are used to transfer XML files in their raw form without revealing their inherent semantics. Also, RFC 7303 advises giving media types with the +xml suffix to XML-based languages, such as image/svg+xml for SVG.
