The 123 file extension is associated with Lotus 1-2-3, a spreadsheet program developed by Lotus Development Corporation and later acquired by IBM. Introduced in 1983, Lotus 1-2-3 was known for its three main capabilities: spreadsheets, charting, and basic database operations. The 123 format, introduced in 1997, replaced earlier formats like WK4 and was used to store data in rows and columns, supporting various functions and calculations. Although IBM discontinued Lotus 1-2-3 in 2013, the 123 file format remains a legacy format.
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.
