What is Excel?
Microsoft Excel is a powerful spreadsheet application developed by Microsoft. It's part of the Microsoft Office suite and has become the industry standard for data organization, analysis, and visualization. Excel uses a grid of cells arranged in numbered rows and letter-named columns to organize data manipulations like arithmetic operations and formulas.
File Format: Excel files use the Open XML format (.xlsx) which is essentially a ZIP archive containing XML files and other media assets. This makes them more efficient and less prone to corruption compared to the older binary format.
Structure: An Excel workbook consists of one or more worksheets, each containing cells organized in rows (numbered 1 to 1,048,576) and columns (labeled A to XFD).
Features: Supports complex formulas, pivot tables, charts, macros (VBA), conditional formatting, data validation, and extensive formatting options.
Data Types: Handles various data types including numbers, text, dates, times, currencies, Boolean values, and errors.
