format file wk4

What is a wk4 file and how do I open a wk4 file?

The .wk4 file extension was developed by IBM because it is mainly used by one of IBM’s Lotus software, the Lotus 1-2-3 version 4. This is a Lotus program that belongs to Lotus SmartSuite, a suite of Lotus spreadsheet programs. This version of Lotus 1-2-3 is another spreadsheet program that allows users to create and save data in spreadsheets. Like the rest of the files used by earlier versions of the Lotus 1-2-3, these .wk4 files are also organized in rows and columns and they are files that are stored in cells as well. They contain formulas that allow users to easily and quickly compute the value of the data displayed in the cells which is why this is mostly used to perform computations. Before, these files could be imported by Microsoft Excel, but it no longer supports the .wk4 extension at present. Applications that can open these files are Lotus 1-2-3 WK4 File Converter, Corel WordPerfect Office X6, Gnumeric, and IBM Lotus 1-2-3.
