One such way to do it programmatically is doing a Scan operation and formatting the data to CSV:
aws dynamodb scan \
--table-name <table_name> \
--select ALL_ATTRIBUTES \
--page-size 500 \
--max-items 10000 \
--output json | jq -r '.Items' | jq -r '(.[0] | keys_unsorted) as $keys | $keys, map([.[ $keys[] ][]?])[] | @csv' > my-table-3.csv
Another way is using AWS Datapipeline to export the table to CSV and stores it directly on S3:
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-template-exportddbtos3.html
And finally you can use AWS Glue to read the DynamoDB table and write to S3 in CSV format:
There is also third party options available, many of which you must pay for such as DynoBase:
