About WKS files

The WKS file type is a spreadsheet file created by Lotus 1-2-3, a popular spreadsheet application from the 1980s and 1990s. It is a proprietary file format that is not compatible with other spreadsheet applications, such as Microsoft Excel. Conversion of WKS files to other formats can be difficult due to the proprietary nature of the file format, and the fact that it is no longer supported by Lotus 1-2-3.

Software such as various tools and appropriate programs can be used to convert WKS files to other formats, such as XLSX, CSV, and HTML. However, these programs may not be able to convert all of the data contained in the WKS file, and some formatting may be lost in the process. Additionally, there may be compatibility issues between the WKS file and the program used to convert it, as the file format is no longer supported by Lotus 1-2-3.

Due to the challenges associated with converting WKS files, it is recommended to use a free and easy online website such as Convert.Guru to convert WKS files. This website provides an easy-to-use interface for converting WKS files to other formats, such as XLSX, CSV, and HTML. Additionally, the website is secure and does not require any software downloads, making it a safe and convenient option for converting WKS files.


The WKS Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best WKS converter by continuously improving quality, usability, and reliability.
