Extract text from CirclePack data files (CIRCLES)
To convert CIRCLES data files to another format, you need CirclePack or other Data software.
To convert other file formats to the "Mathematical Model Data" file type, you need software like CirclePack or a similar tool.
The .circles file extension primarily serves as a mathematical data file for CirclePack, a software built to create and analyze circle packings in discrete conformal geometry. Occasionally, it is also used as a legacy 3D model file for Circles 3D Modeler. Because these files are highly specialized, opening them on a standard computer is notoriously difficult. You cannot double-click a .circles file to view it in your web browser, and analyzing the raw coordinate data in modern tools like Microsoft Excel requires complex manual text parsing. While the underlying data is often plain text, it lacks standard delimiters, making it clunky for data science languages like R or Python.
To make this data useful, you must convert the .circles format into something universally recognized. For data analysis and editing, convert it to CSV or TXT. This instantly organizes the coordinates and vertex data for spreadsheets or scripts. If your specific file contains legacy 3D geometry, converting it to OBJ or STL ensures it will load correctly in modern modeling software like Blender. Just drag and drop your file here to analyze and convert it - free, online, and without installing obscure academic software.
Convert.Guru analyzes your CIRCLES file, detects the exact format, and lets you read the text inside.
Users also converted TAH, LXF and S3D files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CIRCLES converter.
