Technical Details XLSX improves file and data management and data recovery. XLSX extends what is possible with the binary files of earlier versions. Any application that supports XML can access and work with data in the new file format. The application does not need to be a Microsoft product it can be any application. Users can also use standard transformations to extract or repurpose the data. In addition, security concerns are drastically reduced because the information is stored in XML, which is essentially plain text. Thus, the data can pass through corporate firewalls without hindrance.

Description Web pages are predominately marked up in HTML, these are then displayed through browsers such as Safari, Internet Explorer or Mozilla Firefox. It provides a means to describe the structure of text-based information in a document by denoting certain text as headings, paragraphs, links etc and to supplement that text with interactive forms, embedded images, and other objects. HTML source code is used by the Web browser and typically not seen by the user. The RAW HTML can be viewed by choosing View Source from the Web browsers view menu or by opening the HTML file in a text editor.

Technical Details HTML is written using lots of different tags, surrounded by angle brackets. All modern web browsers support the use of HTML4, but more recently the HTML5 has been developed to incorporate many new syntactical features. These include the <video>, <audio>, and <canvas> elements, as well as the integration of SVG content. HTML can also describe, to a certain degree, the appearance and semantics of a document, and is able to include other scripting languages, embeded scripting languages such as JavaScript which can affect the behavior of Web browsers and other HTML processors.
