FAQ

What is XLTX Format?
Files with .xltx extension represent Microsoft Excel Template files that are based on the Office OpenXML file format specifications. It is used to create a standard template file that can be utilized to generate XLSX files that exhibit the same settings as specified in the XLTX file.
What is XLSB Format?
XLSB file format specifies the Excel Binary File Format, which is a collection of records and structures that specify Excel workbook content. The content can include unstructured or semi-structured tables of numbers, text, or both numbers and text, formulas, external data connections, charts and images. Unlike XLSX (which is based on Open XML file format), the XLSB represents binary Excel workbook file. XLSB files can be read and written to faster which makes them useful for working with large files. XLSB is seldom used to store workbooks as XLSX (and previously XLS) are the most common user selected file formats for saving workbooks. It can be opened by Microsoft Office 2007 and above.
