jsonrepair
https://github.com/josdejong/jsonrepair

Repair invalid JSON documents. When a document could not be repaired, the output will be left unchanged.

Usage:
    jsonrepair [filename] {OPTIONS}

Options:
    --version, -v       Show application version
    --help,    -h       Show this message
    --output,  -o       Output file
    --overwrite         Overwrite the input file
    --buffer            Buffer size in bytes, for example 64K (default) or 1M

Example usage:
    jsonrepair broken.json                        # Repair a file, output to console
    jsonrepair broken.json > repaired.json        # Repair a file, output to file
    jsonrepair broken.json --output repaired.json # Repair a file, output to file
    jsonrepair broken.json --overwrite            # Repair a file, replace the file itself
    cat broken.json | jsonrepair                  # Repair data from an input stream
    cat broken.json | jsonrepair > repaired.json  # Repair data from an input stream, output to file
