Become an Excel Genius: Essential Formulas You Must Master
Spreadsheets are the backbone of modern work. Whether managing budgets, analyzing data, or tracking progress, Excel makes it all possible. But to unlock its true power, one must go beyond basic input—the secret lies in mastering the formulas that drive automation, logic, and efficiency.
Why Excel Formulas Matter
Formulas are the brain of Excel. They calculate, sort, and interpret data in real time. When used well, they eliminate guesswork, reduce manual labor, and boost accuracy. A few key formulas can save hours every week. For professionals, these tools are not optional—they are essential.

3. VLOOKUP
Pull data from other tables.

4. INDEX & MATCH
A better alternative to VLOOKUP.

It is more flexible and works even if columns move around.
5. COUNTIF
Count cells based on a condition.

Mastering these formulas bridges the gap between data and decision-making. Even simple reports become powerful tools.
