| Description | The WKS file format is an outdated file format for spreadsheets used by Lotus 1-2-3 software. It was first introduced in 1982 and was widely used during the 1980s and early 1990s before being replaced by the more advanced Lotus 1-2-3 file formats such as .123. |
| Technical details | WKS files are binary files that contain spreadsheet data, including text, numbers, formulas, and formatting. They have a file header that contains information about the file's format and settings, followed by a series of records that describe the contents of each cell in the spreadsheet. The file format uses a proprietary binary format and is not widely supported by modern spreadsheet applications. Each record in a WKS file contains information about a single cell in the spreadsheet, including its row and column location, data type, and value. The data types supported by the WKS file format include text, numbers, dates, and formulas. The format also supports basic formatting options such as font size, bold and italic styles, and cell borders. |
