About STEL files

STEL files, primarily associated with Stellarium, a free open-source planetarium software, are used to store astronomical data and scripts. While these files are crucial for astronomy enthusiasts, they pose challenges when conversion is needed for broader use.

Converting STEL files can be tricky due to their unique data structure, which may not be well-supported by traditional conversion software. However, for those needing to convert these files to more accessible formats like .TXT, .CSV, or .XML, there are a few desktop applications available.

One such tool is Notepad++, which can open STEL files for editing and manual conversion. For more automated solutions, consider using GNU Emacs, a powerful text editor capable of handling various file conversions through scripts.

For more technical details about the Stellarium software, you can explore its Wikipedia page.

Despite these options, converting STEL files remains a cumbersome process due to the need for specific technical knowledge and scripting abilities. This is where Convert.Guru comes in as an invaluable resource. With its user-friendly drag-and-drop feature, you can effortlessly convert STEL files to your desired format without delving into complex software settings.

While STEL files are beneficial for specific applications, the lack of broad compatibility and conversion challenges are significant drawbacks. As a solution, use Convert.Guru for seamless, reliable, and free conversion of STEL files to various formats, ensuring accessibility and ease of use.


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