Opening XLTX files
Did your computer fail to open a XLTX file? We explain what XLTX files are and recommend software that we know can open or convert your XLTX files.
What is a XLTX file?
The .xltx file extension is most commonly used by the Microsoft Excel spreadsheet application. The XLTX files contain template files that have been created with the Excel software. These files contain default settings and layout information, allowing a user to create multiple spreadsheets with the same layout and formatting without creating each spreadsheet from scratch. The XLTX file format is used by versions of Excel 2007 and later and use zip compression technology to save a user's disk space.
Software that will open, convert or fix XLTX files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
