QJsonParseError::UnterminatedObject 1 An object is not correctly terminated with a closing curly bracket
QJsonParseError::MissingNameSeparator 2 A comma separating different items is missing
QJsonParseError::UnterminatedArray 3 The array is not correctly terminated with a closing square bracket
QJsonParseError::MissingValueSeparator 4 A colon separating keys from values inside objects is missing
QJsonParseError::IllegalValue 5 The value is illegal
QJsonParseError::TerminationByNumber 6 The input stream ended while parsing a number
QJsonParseError::IllegalNumber 7 The number is not well formed
QJsonParseError::IllegalEscapeSequence 8 An illegal escape sequence occurred in the input
QJsonParseError::IllegalUTF8String 9 An illegal UTF8 sequence occurred in the input
QJsonParseError::UnterminatedString 10 A string wasn't terminated with a quote
QJsonParseError::MissingObject 11 An object was expected but couldn't be found
QJsonParseError::DeepNesting 12 The JSON document is too deeply nested for the parser to parse it
QJsonParseError::DocumentTooLarge 13 The JSON document is too large for the parser to parse it
