Overview
An 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 description
It 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). Furthermore, including Version 12.0 and later ones, can have 1048576 rows and 16384 columns.

Overview
This extension is predominantly used to design web pages which are displayed by different browsers such as Safari, Internet Explorer, Mozilla Firefox and Google; etc. Web browsers get the HTML document from a web server and in return, generate the document into multimedia web pages on a user's device. The source code can be viewed by choosing an option ‘View page source' (appears on right-click) from a web page or by using a shortcut that is ‘Ctrl + U'. In actual words, this format directs the browser on how to exhibit the words and images of a web page to the user. It may include images, audio, video and scripts as well.
Technical description
It helps to create a structured document where semantics are used to display text such as paragraphs, headings, hyperlinks, tables and quotes; etc. The building blocks of HTML pages are their elements which are designed by tags using angle brackets. For example, <img /> and <input /> tags help to submit content into the page, <p> tag provides information about the document text, . Apart from this, the technologies that support this format are CSS (Cascading Style Sheets) and JavaScript, which is a scripting language. Here is a list of few basic elements or tags. <head> for metadata, <body> defines the body of the webpage, <h1> text header for creating a text title, <p> specify a paragraph, <img> to embed an image, <ul> to indicate an unordered list with no numerical order or bullet list and <div> used to define sections or divisions.
