Open XLSX File Online

XLSX files are Microsoft Excel text files that are evolutionary from XLS. With the release of the 2007 version of Excel, the format was introduced as a new standard for spreadsheet documents. The goal was to establish an XML-based file format that required less storage capacity. The name XLSX is a combination of the popular XLS extension and the X for XML. This format contains a set of packages in XML, being more practical to archive, since it can be decompressed with software external to Office Suite and allows easy sending via email. The XLSX file belongs to the Office Open XML standard (also called OOXML or OpenXML), being an open file format. This type of file improves file and data management and expands the possibilities with binary files compared to previous versions of Microsoft Excel. Storing information in XML format represents an increase in security, which is essentially plain text.
