What is a .WK5 file?

The .WK5 file extension is associated with a Lotus 5 Worksheet, which is a type of spreadsheet file. This file format was specifically created for use with Lotus 1-2-3 version 5, a popular spreadsheet program in the past. A .WK5 file includes data organized in rows and columns. It can contain various types of data such as numbers, text, and formulas that perform calculations. This makes it useful for tasks like data analysis, budgeting, and financial forecasting.

Although the original program, IBM Lotus 1-2-3, that was used to create and open .WK5 files has been discontinued, you can still access these files using other software. Microsoft Excel 365, a modern spreadsheet program, is capable of opening .WK5 files. This allows users to view, edit, and manage the data within these files even though the original software is no longer available.
