tools – Microsoft – Excel

Excel is a spreadsheet program used to organize, calculate, analyze, and visualize data. In simple terms, it can:

• Store & organize data in rows and columns (like a smart table).
• Calculate everything from basic math to complex formulas using built-in functions (SUM, IF, VLOOKUP).
• Analyze large datasets quickly with PivotTables, filters, and what-if scenarios.
• Create charts (bar, line, pie) to visualize trends.
• Automate repetitive tasks using macros and Office Scripts.
• Import data from external sources (CSV, databases, web).
• Collaborate in real-time with others online.

Common uses: Budgeting, sales reports, gradebooks, inventory tracking, and financial modeling.

Limitations: Not great for massive datasets (over ~1 million rows) or advanced version control.
