What is this xltx file?

Template file used by Microsoft Excel 2007. New file extensions and file formats for Excel Spreadsheets based on Open XML data format. XLSX file format was introduced with Microsoft Excel 2007. XSLX files uses ZIP compression for smaller file sizes. Following the advent of XML in the 1990s, corporate computing customers began to realize the business value in adopting open formats and standardization in the computer products and applications that they relied on. IT professionals benefited from the common data format possible with XML because of its capacity to be read by applications, platforms, and Internet browsers. Likewise, with the adoption of support for XML in Microsoft Office 2000, developers began to see the need to transition from the binary file formats seen in previous versions of Microsoft Office to the XML format. Binary files (.doc, .dot, .xls, and .ppt files), which for years did a great job of storing and transporting data, were not able to meet the new workplace challenges that included easily moving data between disparate applications, and allowing users to glean business insight from that data. The 2007 Microsoft Office system continues with this transition by adopting an XML-based file format for Microsoft Office Excel 2007, Microsoft Office Word 2007, and Microsoft Office PowerPoint 2007. The new file format, called Office Open XML Formats, addresses these workplace issues with changes that affect the way that you approach solutions based on Microsoft Office documents. The new formats improve file and data management, data recovery, and interoperability with line-of-business systems. They extend 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 part of the Microsoft Office system or even a Microsoft product. 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.
