Is there anyway to make this possible through configuration changes while parsing/indexing the log file itself

From the below raw data only json need to be extracted/indexed in the splunk and should be viewed as json structured view while searching this logs on search head

ExSrc:Schwab.Client.Fx^
URL:null^
LogMsg:{"actor":{"Cust":null,"Acct":null,"Rep":null,"System":null},"header":{"AppId":null,"RecId":"null","Ver":"","StartTS":"null"},"source":{"Ip":"*","MacAddress":null,"SRCOS":"null","SRCRuntime":null,"SRCAppName":null,"SRCAppVersion":null,"SRCReqId":"null","CorrelationId":"null","SourceId":null,"Uri":"null"}}^
