TLE to JSON / CSV Converter
Convert NORAD two-line element sets to modern CCSDS OMM/GP JSON or flat CSV — single satellites or entire catalogs. Everything runs in your browser; nothing is uploaded.
OMM/GP JSON is the modern CCSDS-based format used by CelesTrak and space-track.org — field names like MEAN_MOTION, RA_OF_ASC_NODE, and BSTAR map directly from the fixed-width TLE columns.
Records with bad checksums are still converted but flagged — check the source data before propagating. To decode a single TLE field-by-field, use the TLE Parser.
