What is an XLTX file?

XLTX files mostly belong to Excel by Microsoft. An XLTX file is a workbook (spreadsheet) template bundled with Excel or created by a user. The format was introduced in Excel 2007 and adopted as the primary format for saving a template in Excel 2010. An XLTX file contains spreadsheet placeholder data which serves as scaffolding for creating a new XLSX workbook. Like XLSX files, an XLTX template is saved in Office Open XML format. For this reason, such a spreadsheet template is actually a compressed ZIP archive containing XML-encoded data, settings, embedded images/objects, and metadata. This format does not support Visual Basic for Application macros.
