I have a json file which has the information inside and available in my s3 bucket can we transfer those information to the cloudtrail ? If yes than how also what is the format of data we can transfer from s3 bucket to cloudtrail.
AFAIK CloudWatch does not support S3 as a data source, only as a storage destination.
Whatever data you are storing in S3 that you want to analyze, you should send that to CloudWatch first.
I assume that you wanted to integrate the two sources to correlate the events. If that is the case, you should look at merging them in Quicksight or a 3rd party reporting / alerting tool.
Also have a look at AWS Timestream for time based data management.
