How to schedule a .csv report:

1. Go to Reports and select metrics and dimensions you want to see in your report

2. Preview up to 200 rows of report data. If you need to make changes, select Back to adjust your metrics and dimensions, or select Next to continue

3. Name the report and define the frequency (daily/weekly/monthly);

4. Define the period during which you want to receive this report.

5. Add recipients of your report (optional)

You can then update the reporting cadence or timeframe by editing the existing report. 

Note: scheduled reports can only be sent to users associated with your Ads Manager account.
