WKS Document Format

WKS Converter

WKS is the format that was used with the now-discontinued Lotus 1-2-3 spreadsheet software. In the 1980s and early 1990s, before Microsoft Excel overtook it in use, Lotus 1-2-3 was probably the most popular spreadsheet program. The software was widely used in both homes and offices. Like Excel formats, WKS stores data in cells in grids and rows, and you could use Lotus 1-2-3 to calculate formulas and create charts.

Lotus was sold to IBM and the final version of Lotus 1-2-3 was released in 2002, with support ending in 2013. Because it used to be such a common format, you can still open WKS files in many spreadsheet programs. These include Excel 2003 and earlier, Corel QuattroPro and OpenOffice Calc. However, many users prefer to convert WKS files into Excel or CSV, as the format and software have since been discontinued.

XLSX Document Format

XLSX Converter

XLSX is a file type created using Microsoft Excel - part of the Microsoft Office Suite software. This file format is a zipped Open XML-based file type, meaning it compresses or reduces the file size so that it can access stored data faster and be easily shared with other programs. XLSX was developed by Microsoft as part of their Office 2007 development and is now the default file format for Excel.

XLSX files are very similar in their functionality to their predecessor, XLS; they can be used to create spreadsheets, charts and graphs, process mathematical formulae, and to share or analyse data. The main difference between XLSX and XLS is in how the data is stored. Whereas XLS files hold data in a single file, XLSX saves data in the Open XML format, with separate files zipped up together to reduce space. This also means that XLSX files can present larger data sets and have a greater range of cells. As well as with Microsoft Excel, XLSX files can be opened using various other programs, including Google Sheets, LibreOffice, and Apple Numbers.
