XLSX Viewer & XLSX Reader

What is XLSX? XLSX is the new format for Microsoft Office documents. It is a combination of XML architecture and ZIP compression for size reduction. XLSX files are backwards compatible with Microsoft Excel 2000 and 2003 via component support; they are also recognized by Microsoft Windows Server with the GemBox.Spreadsheet .NET component. It is compatible with Microsoft Excel 2007. New file extensions and file formats for Excel Spreadsheets based on Open XML data format.

The new formats XLSX 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.
