In Power BI Desktop, walk me through connecting to an Excel workbook that contains multiple sheets. Describe how you would use Power Query to: combine the sheets into a single clean table, promote headers correctly, remove null or header rows, change data types reliably, and add a column that records the source sheet/file name. Finally, explain how you'd publish the dataset to Power BI Service and set a basic scheduled refresh.

Given a table fact_subscriptions(customer_id, start_date, end_date, billing_date), write a DAX-based approach (sample code) to compute cohort retention rates by subscription month. Your solution should produce a retention matrix where each row is a cohort month and each column shows % of customers still active after N months. Explain performance considerations and alternatives for large datasets.
