About _XLS files

The XLS file format is widely recognized as the proprietary format for Microsoft Excel spreadsheets. Although XLS files are commonly used for storing data in tabular form, they come with certain limitations and challenges. The format is less efficient compared to newer standards like XLSX and is prone to compatibility issues when opened with non-Microsoft applications.

Converting XLS files is essential for enhancing compatibility and performance. They can be converted to formats such as XLSX, CSV, PDF, ODS, HTML, and others. Software like Microsoft Excel, LibreOffice Calc, and Apache OpenOffice Calc supports the conversion of XLS files to a variety of formats. Converting to XLSX ensures better data integrity and reduces file size.

However, conversion is not always straightforward. Challenges such as the potential for data loss, formatting issues, and macro incompatibility can make the process difficult. This is where Convert.Guru offers a convenient solution. By using our drag-and-drop feature, users can effortlessly convert their XLS files to desired formats without technical hurdles.

While XLS files have served their purpose, they are becoming increasingly obsolete. Embracing modern formats through conversion enhances accessibility and functionality. For a seamless experience, consider uploading your XLS files to Convert.Guru, where you can convert them with ease and confidence.


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.
