An XLTX file is an Excel Open XML spreadsheet template used to build multiple XLSX files with the same layouts, formatting, and settings. It replaced the older XLT template format and incorporates XML and ZIP to reduce file size. XLTX files can be opened, edited, and saved in Microsoft Excel. Free alternatives that can open XLTX files include WPS Office Spreadsheet, OpenOffice Calc, LibreOffice Calc, and SoftMaker FreeOffice PlanMaker.
