Parses replay files generated by the game Rocket League. Parses to C# objects, which can be serialized to JSON.

Supports all replay files created by Rocket League version 2.54 (released 2025-07-29) and earlier. Newer versions may work as well - updates don't always change the replay format. Changes to the replay format are usually supported within a few days. Please create an issue for any replays that fail to parse, or for replays that parse incorrectly.

Includes a library that can be used in your project (Install-Package RocketLeagueReplayParser) as well as a basic console based front end that can be used to convert a replay file to JSON.

• Convert a single replay file to JSON, outputting the result to stdout

RocketLeagueReplayParser.exe example.replay

• Convert a single replay file to JSON, outputting the result to a file (named .json)

RocketLeagueReplayParser.exe example.replay --fileoutput

• Convert all replay files in a directory to JSON, outputting the result to files

RocketLeagueReplayParser.exe "\\path\to\replay\files" --fileoutput --d

Further instructions can be found by running RocketLeagueReplayParser.exe --help

This was the first project that could parse replays all the way! For a good while it was the reference implentation for all others. Thankfully others have taken that on in the years since.
