About XLS files
XLS files are a type of spreadsheet file created by Microsoft Excel.
They are a popular file type for organizing and storing data, but they can be difficult to work with. XLS files are proprietary and require specialized software to open, edit, and convert them. Microsoft Excel is the most popular software for working with XLS files, but there are also open-source alternatives such as LibreOffice Calc and Apache OpenOffice Calc. XLS files can be converted to other formats, such as CSV, HTML, PDF, and XML. However, the process can be difficult and time-consuming, and the results may not be accurate. For example, some formatting and formulas may not be preserved in the conversion process. Additionally, XLS files can be large and difficult to share, so it is important to consider the size of the file when converting.
For these reasons, it is often best to use a free and easy online website such as Convert.Guru to convert XLS files. This website allows users to quickly and easily convert XLS files to other formats, such as CSV, HTML, PDF, and XML. Additionally, the website is secure and provides a variety of features to make the conversion process easier.
In conclusion, XLS files are a popular file type for organizing and storing data, but they can be difficult to work with. For these reasons, it is often best to use an online website such as Convert.Guru to quickly and easily convert XLS files to other formats.
The XLS 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 XLS converter by continuously improving quality, usability, and reliability.
