Lotus 1-2-3 was a spreadsheet application originally developed by Lotus Development Corporation and later marketed by IBM. The software was available for Microsoft Windows, MS-DOS, OS/2 and Mac OS Classic.
The wj3 file extension is used for a worksheet created by Lotus 1-2-3 version 2.4J. The file can contain the worksheet's data and spreadsheet calculations.
The format is obsolete because Lotus 1-2-3 is no longer developed or commonly used. Its associated MIME type is application/vnd.lotus-1-2-3.
Open a wj3 file with Lotus 1-2-3 for Microsoft Windows. Because the software is obsolete, it may require an older Windows environment or a compatible legacy system.
Open the wj3 file in Lotus 1-2-3 and use its save or export functions to create a file in another format supported by that version. If Lotus 1-2-3 is unavailable, conversion may require access to a compatible legacy installation first.
