What is the .WK1 File Extension?


.WK1 File Extension Description:

The WK1 file extension is natively owned by IBM Corporation for usage with the Lotus 123 Spreadsheet. Lotus 1-2-3 was made available to the public in 1983, outselling the then popular VisiCalc. It remained the most leading spreadsheet solution for several years for the MS DOS environment.

The file extension WK1 identifies a Lotus Worksheet that was created with the Lotus 1-2-3 Spreadsheet version 2. Files with the .wk1 file extension are used for storing information, with the actual goal of producing charts, reports, and other analysis, as well as calculation operations.

Lotus 1-2-3 was designed in order to achieve its "1-2-3" purpose, which is the integration of three capabilities: spreadsheet solution, integral charting/graphing, and database operations. The main concept of a spreadsheet solution is to replicate a given spreadsheet, provide it with built in formulas, programmed calculations, other useful computations, and automatic updates, and then, save the resulting file with the .wk1 file extension.

In order to format Lotus 123's fonts, borders and shading are used as add-ins in which it contains various methods for compiling format information based on the range size and complexity of the cells being formatted. With Impress, saving the file with the .wk1 file extension saves the format information in a separate file that has the same name as the worksheet file but it ends with the FMT file extension.

When a large amount of information is stored in the file with the .wk1 file extension, Microsoft Excel cannot recognize the method used. Thus, when a user opens a file with the .wk1 file extension in Excel, even the file directory is searched. If the corresponding file with the .fmt file extension were identified, the file with the .wk1 file extension can be imported and its format information can then be applied.

Files with the .wk1 file extension can also be imported if Lotus for MS-DOS version 3.0 or Lotus for Windows version 1.0 were available, after which, they can be saved into files with the .wk3 file extension along with the creation of its corresponding file with the .fm3 file extension. Once the file is in the version 3 format, the file with the .wk1 file extension can be opened in Excel with all of it's formatting intact.
