Description🔵 WK1 is a spreadsheet file format used by Lotus 1-2-3, a popular spreadsheet software in the 1980s and 1990s. It was 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 used for storing spreadsheet data, formulas, formatting, and other information.
Technical details🔵 The WK1 format is a binary file format that stores data in rows and columns. The file consists of a series of records, each of which contains information about the spreadsheet, such as the number of rows and columns, the width and height of each cell, the formatting information for the cells, and the data contained in the cells. The data in the file is organized into sheets, with each sheet containing a separate table of rows and columns. The WK1 format supports a wide range of formatting options, including font styles, borders, colors, and alignment. It also supports a variety of mathematical and logical functions that can be used to manipulate data in the spreadsheet. Additionally, the WK1 format supports charts and graphs, which can be created and embedded within the spreadsheet.

Description🔵 .xls The .xls format is the default file format for spreadsheets created in Microsoft Excel, particularly in versions before Excel 007. 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 dataThe .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 for Microsoft Excel versions before 2007, stores spreadsheet elements like worksheets, formulas, and macros. As a proprietary binary format by Microsoft, its undocumented internal structure made third-party software compatibility challenging. This format includes binary records encapsulating data, formatting, and embedded objects, supporting multiple worksheets, various functions, and inter-sheet referencing. `.xls` files may contain Visual Basic for Applications (VBA) macros, enabling automation and complex calculations. It's supported not just in Excel but also in applications like OpenOffice Calc, with options to convert between `.xls` and other formats like `.xlsx`. Despite security concerns with macros, `.xls` is still used, mainly for its compatibility with older Excel versions and legacy systems, although the newer `.xlsx` format, introduced in Office 2007 with XML and ZIP technologies, offers improved efficiency and security.
