FAQ
Which tool should I choose – Tableau or Excel?
If you need enterprise-level analytics, scalability, or executive dashboards, Tableau is the best choice. Excel works well for quick reporting or smaller datasets. I’ll recommend the right tool after reviewing your data.
What types of data can you work with?
I work with various types of data including sales, customer behavior, marketing, finance, healthcare, and survey data. I handle data from Excel, Google Sheets, SQL databases, APIs, and CSVs for use in Tableau dashboards.
Can you help us integrate multiple data sources into a single analysis?
Absolutely! I can join and blend data from Excel, SQL, Google Sheets, and other sources directly in Tableau to create a unified, insightful dashboard with accurate visual analysis.
Can you customize visualizations based on specific business requirements?
Definitely. I tailor each Tableau dashboard to your business goals, KPIs, and industry needs—whether it's sales tracking, executive reporting, or customer analysis.
