BigQuery Saved Me From Excel Hell

My previous job involved analyzing CSV files. Gigabytes of them. Excel would crash. My laptop would overheat. I spent hours writing VLOOKUPs that took minutes to calculate. Then I discovered BigQuery. It's a data warehouse that can query terabytes of data in seconds. I uploaded my CSVs to Cloud Storage, linked them to BigQuery, and wrote SQL queries that would have taken Excel an hour. They ran in three seconds. I could join multiple datasets. I could analyze years of data at once. My laptop stayed cool. My sanity returned. BigQuery made me look like a data wizard when really I was just using the right tool. If you're still fighting with Excel for large datasets, do yourself a favor. Try BigQuery. Your computer will thank you.
