Bills csv export

Thank you for your question about downloading AWS billing information to CSV format. I'll address your concerns:

1. Since you enabled the Monthly Usage Report in the Detailed Billing Reports (Legacy) section on February 24th, you will only be able to download the CSV reports for billing periods starting after that date. This means you won't be able to download CSV reports for January or February. The reports will be available starting from March (the first full month after enabling the feature).

2. Regarding your requirement to download bills to CSV, you have a couple of options:

   a. For future months (starting from March), you'll be able to use the "Download all to CSV" option from the Bills page once the Monthly Usage Report becomes available.

   b. For more immediate access to billing data in CSV format, you can use the Cost Explorer export feature. While this isn't exactly the same as the bill CSV, it provides detailed cost and usage data that you can download in CSV format. To do this:

   • Go to the AWS Cost Management console
   • Use Cost Explorer to configure the view of your cost data as needed
   • Select the "Download CSV" option to get your filtered cost data in CSV format

It's important to note that while the legacy Detailed Billing Reports are still available, AWS recommends using the more comprehensive AWS Cost and Usage Reports for the most up-to-date and detailed billing information. However, if your specific requirement is to download the bills in CSV format, the options mentioned above should help you achieve that goal.

Remember that the CSV file from Cost Explorer may have a slightly different format compared to the billing CSV, with columns representing costs and rows representing time, which is the reverse of what you see in the Cost Explorer data table in the console.

If you need historical data for January and February, you may need to explore other options or contact AWS support for assistance in retrieving that information in CSV format.
