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 XLSM file extension stands for Microsoft Excel Macro-Enabled Spreadsheet. It allows users to automate tasks via macros, enhancing productivity in complex data manipulation and repetitive operations. Introduced with Excel 2007 as part of the Office Open XML format, XLSM files support the embedding of VBA (Visual Basic for Applications) macros within spreadsheets. This format offers advanced functionalities for financial analysis, data modeling, and automation within the Microsoft Excel environment, optimizing efficiency for professional use.
