What is XLTX?
XLTX is a file format used by Microsoft Excel to save template files. It is an XML-based template format that allows users to create Excel files with pre-defined formatting, formulas, and styles which can be reused for future spreadsheets, enhancing productivity and consistency.
Loss of Macros
XLTX files do not support macros, which means any Excel templates that rely on VBA code will lose this functionality when converted to XLTX.
Compatibility Issues
Some features or formatting from older versions of Excel may not translate properly into the XLTX format, especially if the original file uses functions or formatting that are not supported in the newer XML-based structure.
Inability to Save as a Binary File
When converting to XLTX, users cannot save files in a binary format (XLTX), which can limit performance with large datasets because file sizes may increase.
Loss of External Links
External links to other workbooks or data sources may break during conversion, leading to errors or missing data in the template after saving it as XLTX.
