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.

Description	🔵 The .xls format is the default file format for spreadsheets created in Microsoft Excel, particularly in versions before Excel 2007. This binary file format can store data in cells organized in rows and columns, and it supports formulas, charts, graphs, and various formatting features to manipulate and visualize data. The .xls format was commonly used in business, finance, and any field requiring data analysis and presentation, but has since been largely replaced by the more advanced .xlsx format.
Technical details	🔵 The `.xls` format, primarily used for Microsoft Excel versions before 2007, stores spreadsheet elements such as worksheets, formulas, and macros. Being a proprietary binary format created by Microsoft, its undocumented internal structure has made compatibility with third-party software quite challenging. This format consists of binary records that contain data, formatting, and embedded objects, allowing for multiple worksheets, various functions, and inter-sheet referencing. `.xls` files can also include Visual Basic for Applications (VBA) macros, which enable automation and complex calculations. While supported in applications like OpenOffice Calc, there are options available to convert between `.xls` and other formats such as `.xlsx`. Despite security concerns related to macros, `.xls` is still commonly used due to its compatibility with older Excel versions and legacy systems. However, the newer `.xlsx` format, introduced in Office 2007 and utilizing XML and ZIP technologies, offers improved efficiency and security features.
