About DashCore Hub

DashCore Hub is an independent, bilingual learning site about business intelligence (BI). We publish free, practical guides on Excel, Power BI, Tableau, Data Studio, SQL, Python and AI — written for beginners, small-business owners and professionals who want to make better decisions with data.

What we believe

BI is moving fast, and AI is changing how reports get built. You still need the fundamentals: clean data, a good model and clear visuals. Our guides teach the fundamentals first and then show how AI can speed up each step.

How we create content

Our editorial team writes and reviews each guide for technical accuracy. Formulas, DAX, SQL and Python examples are written to work as shown. Product features and pricing change often, so we link to official sources and update articles when things change. If you spot an error, please tell us.

How we make money

The site is free. We earn from display ads, affiliate links (such as Amazon and online course platforms) and our own templates. This never changes what we recommend. See our affiliate disclosure.
