Get all A Records from route 53 using CLI and export to CSV

There isnt a way to do this natively

You can try this cli command (from here)

aws route53 list-resource-record-sets --hosted-zone-id "/hostedzone/Z#################" | jq -r '.ResourceRecordSets[] | [.Name, .Type, (.ResourceRecords[]? | .Value), .AliasTarget.DNSName?] | @csv'

You may have issues if there are more than 1000 record sets as you will hit the pagination limit.

You can also try a third party too like cli53 that can export the zone to BIND format
