# Output CLI Results In Different Formats
The AWS CLI can output the results of commands in three different formats.
- Text
- JSON
- Table
The _default_ output format for my AWS CLI is currently configured to `json`.
```bash
$ aws configure get output
json
```
I can either accept the default or I can override it with the `--output` flag.
```bash
$ aws rds describe-db-instances \
--query 'DBInstances[*].Endpoint' \
--no-cli-pager
[
{
"Address": "fc-database-abcefg-ab1c23de.asdfgh4zxcvb.us-east-2.rds.amazonaws.com",
"Port": 5432,
"HostedZoneId": "A1BCDE2FG345H6"
}
]
$ aws rds describe-db-instances \
--query 'DBInstances[*].Endpoint' \
--no-cli-pager \
--output table
