jsonrepair repairs invalid JSON documents. It can correct many common syntax problems automatically, making malformed or incomplete JSON usable without manually locating and fixing every error.
The software is available both as a library and a command-line utility. It also provides a streaming implementation for processing very large documents without loading the entire input into memory.
This is free and open source software.
