What is an XLT file?
The XLT format is a legacy spreadsheet template file used by Microsoft Excel versions 97 through 2003. It utilizes the proprietary Binary Interchange File Format (BIFF8), storing formatting, formulas, and baseline data in a binary stream rather than the XML structure of modern formats. These templates serve as blueprints for generating new .XLS workbooks with consistent layouts, preventing the overwriting of the original template file upon saving.
How to open an XLT file
Modern versions of Microsoft Excel retain backward compatibility for XLT files, automatically converting them to the newer XLTX or XLTM format upon saving. Third-party applications such as LibreOffice Calc and Kingsoft Spreadsheets can render XLT templates, though complex formatting or legacy macros may require adjustment. Google Sheets supports importing XLT files, converting them to the native Google Sheets format.

What is an ODS file?
The OpenDocument Spreadsheet (ODS) format is an XML-based file standard for spreadsheets, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). Standardized as ISO/IEC 26300, ODS utilizes a ZIP-compressed container holding separate XML files for content (content.xml), styles, and metadata. It serves as the native file format for the LibreOffice and Apache OpenOffice suites, offering a vendor-neutral alternative to proprietary formats by strictly adhering to the OpenDocument Format (ODF) specifications.
How to open an ODS file
ODS files are natively supported by open-source suites such as LibreOffice Calc and Apache OpenOffice on Linux, Windows, and macOS. Microsoft Excel (versions 2007 SP2 and later) includes built-in support for opening and saving ODS files, though some formatting variations may occur due to ODF version differences. Google Sheets also provides cloud-based support for importing and editing this format.
