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 XLTX file extension stands for "Excel Open XML Spreadsheet Template" and is a file format used by Microsoft Excel. Introduced with Excel 2007 as part of the Office Open XML standard, it enhances the functionality of the older XLT format. XLTX files serve as templates that store predefined formatting, formulas, and styles, enabling users to create consistent and structured spreadsheets efficiently. This format supports advanced features and reduces file size, ensuring compatibility across different platforms. It remains a crucial tool for IT specialists to streamline repetitive tasks and maintain uniformity in data presentation.
