🚀 Quick Start

New to Engineer Your Data? Start with these 5 essential operations:

1. Check Data Quality: "Generate a data quality report for my sales.csv file"

2. Find Issues: "Check for null values in the customer_data.csv"

3. Transform Data: "Filter the orders.csv for rows where status is 'completed'"

4. Visualize: "Create a bar chart showing sales by region from revenue.csv"

5. Summarize: "Give me a statistical summary of the dataset"

These cover 80% of daily data engineering tasks. Explore the full capabilities below!
