| Description | 🔵 WK1 is a spreadsheet file format used by Lotus 1-2-3, a popular spreadsheet software in the 1980s and 1990s. It served as the primary format for Lotus 1-2-3 until the release of Lotus 1-2-3 version 9, which introduced the WK3 format. The WK1 format was utilized for storage of spreadsheet data, formulas, formatting, and other information. |
| Technical details | 🔵 The WK1 format is a binary file format used to store data in rows and columns. Each file consists of a series of records containing information about the spreadsheet, such as the number of rows and columns, the size of each cell, formatting details, and the actual data within the cells. The data is organized into sheets, with each sheet representing a separate table of rows and columns. The WK1 format offers a wide range of formatting choices, including font styles, borders, colors, and alignment. It also supports various mathematical and logical functions for manipulating data in the spreadsheet. Additionally, the WK1 format allows for the creation and embedding of charts and graphs within the spreadsheet. |
