Convert XLC to XLT

The XLC file extension stands for "Excel Chart" and is associated with Microsoft Excel. This format was historically used to store chart data and formatting information separately from the main Excel workbook. Originating in earlier versions of Excel, the XLC format allowed for specialized chart manipulation and presentation. However, with advancements in Excel, the need for a separate chart file extension has diminished, and XLC files have become largely obsolete. Modern Excel versions integrate chart data directly within the primary workbook file, simplifying data management and accessibility.

The XLT file extension stands for Microsoft Excel Spreadsheet Template. It is used in Microsoft Excel versions 97 through 2003 to create templates containing default formatting, layout, and formulas. These templates serve as a starting point for generating new spreadsheets with consistent design and structure. Although replaced by the XLTX format in Excel 2007 and later versions, XLT files are still supported for backward compatibility.
