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 XLTX file is an Excel Open XML spreadsheet template used to build multiple XLSX files with the same layouts and formatting. It can be opened, edited, and saved in Microsoft Excel. XLTX uses XML as data structure and ZIP as data compression to reduce the file size.
