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.
An XLSM file is a macro-enabled Excel workbook created in Excel 2007 or later. It is similar to an XLSX file but can execute embedded macros programmed in VBA. Data is stored in cells arranged in rows and columns and can be organized within separate sheets in a single workbook.
