About TLE files

A .TLE file (Two-Line Element set) is a legacy text-based data format used by NORAD and US Space Command to track Earth-orbiting satellites. While efficient for the 1970s punch cards it was designed for, the format is a major friction point for modern developers and analysts. The file consists of 70-column lines containing cryptic encoded values - such as mean motion, eccentricity, and inclination - without any headers or labels. Consequently, you cannot simply double-click to view meaningful data; opening it in a standard text editor just reveals strings of numbers that require a specialized parser to interpret. Users typically need to convert .TLE files into structured formats like CSV for analysis in Microsoft Excel, JSON for web applications, or KML for 3D visualization in Google Earth.

Convert.Guru analyzes your TLE file, detects the exact format, and lets you read the text inside.

Users also converted SCORE, VTP and GPX files.
