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.
XLSX is a file format used by Microsoft Excel for storing spreadsheet data. Introduced with the release of Excel 2007 as part of the Office Open XML standard, it is now the default format for creating spreadsheets using modern versions of Excel. XLSX files are XML-based and have a more open structure than the older XLS format, allowing for smaller file sizes and better recovery of information from damaged files.
