Questions & Answers
XLTX documents: Frequently Asked Questions
What are XLTX files?
XLTX is the Office Open XML template format of Excel, with the same ZIP package structure as an XLSX file. What makes it a template is its purpose: it holds the starting point for new workbooks, namely the sheets with their headings and structure, the cell and number formats, the styles, the formulas that are already entered, the data validation rules, the charts, and the print settings. When the user double-clicks an XLTX file or chooses it in the New window of Excel, the program creates a new workbook that is based on the template, with the name of the form Book1 or similar, so the original is not overwritten by accident. A template of this type cannot contain macros, and a template with macros uses the XLTM extension. The older binary form is the .xlt file. The media type is application/vnd.openxmlformats-officedocument.spreadsheetml.template. Supported by Microsoft Excel.
