About _XLSX files

XLSX is a file format created by Microsoft Excel, part of the Microsoft Office suite. It is commonly used for storing spreadsheets and includes data like numbers, text, and formulas across tables. Despite its widespread use, converting XLSX files can sometimes be challenging due to the intricacies of spreadsheet data.

Conversion Options: XLSX files can be converted to various formats, including CSV, PDF, DOCX, ODT, and HTML. Using software like Microsoft Excel itself, LibreOffice, and Apache OpenOffice, users can perform these conversions offline.

Considerations and Challenges: Converting XLSX files can sometimes lead to compatibility issues, such as loss of formulas, formatting discrepancies, or unsupported features in the target format. Additionally, large files may pose performance challenges during conversion.

Why Choose Convert.Guru? With these challenges in mind, Convert.Guru offers a free and user-friendly solution to convert your XLSX files effortlessly. Users can simply drag and drop their files onto the website to convert them into the desired format with ease and reliability.

While XLSX is a robust format, understanding its limitations and conversion challenges is essential. For a smooth experience.


The _XLSX 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 _XLSX converter by continuously improving quality, usability, and reliability.
