Comprehensive Guide to Excel Basics

I. Workbook, Worksheet, and Cell

1.Workbook

An Excel file is called a workbook, functioning like a folder filled with spreadsheets. A workbook can contain multiple worksheets, making it convenient to categorize and manage different types of data. For example, in a company’s financial workbook, you could have separate sheets for recording income, expenses, and balance sheets.

2.Worksheet

A worksheet is a grid-like table within a workbook, made up of rows and columns. Worksheet tabs are located at the bottom of the workbook and are used to distinguish between different sheets. You can switch between worksheets by clicking their tabs. A worksheet serves as a large grid to record and process various data.

3.Cell

A cell is the smallest data storage unit in a worksheet, identified by column letters (A, B, C, etc.) and row numbers (1, 2, 3, etc.). For instance, cell A1 represents the cell in the first column and first row. Cells can store text, numbers, dates, formulas, and more. In a student grade sheet, cell A1 might contain the text “Name,” while cell B2 could store a student's math score.

II. Data Entry

4.Text Entry

Simply type text into a cell, such as names or addresses. If the text is too long, Excel adjusts the display automatically, or you can manually adjust the column width to show the full content.

5.Number Entry

When entering numbers, Excel automatically recognizes the type of number you input. You can enter integers, decimals, or numbers in scientific notation, such as 123 or 3.14. To input numbers starting with a zero (e.g., 001), you must first set the cell format to “Text”; otherwise, Excel will remove the leading zero by default.

6.Date and Time Entry

Dates can be entered in various formats, such as “2024/1/1,” “2024-1-1,” or “1-Jan-2024.” Excel will automatically recognize and store them as dates. Time can be entered as “13:00” or “1 PM.” You can also combine date and time, such as “2024/1/1 13:00.”

III. Data Formatting

7.Number Formats

Excel offers multiple number formats, including General, Number, Currency, and Percentage. You can set these formats through the “Number” group in the “Home” menu. For example, setting a number to Currency format will automatically add a currency symbol and display the number with the specified decimal places. Setting it to Percentage format will convert the number into a percentage.

8.Text Formats

You can format text content by changing the font, size, color, and alignment. These options are available in the “Font” and “Alignment” groups in the “Home” menu. For instance, you can make titles bold, larger, and center-aligned to improve readability and aesthetics.

9.Date and Time Formats

You can customize the display format for dates and times. Use the dropdown menu in the “Number” group to choose options like long date, short date, 24-hour time, or 12-hour time formats.

IV. Basic Formulas and Functions

10.Formulas

Formulas are the core tool for calculations in Excel. A formula begins with “=,” followed by an expression. For example, “=A1 + B1” adds the numbers in cells A1 and B1. Formulas can include arithmetic operators such as addition (+), subtraction (-), multiplication (*), and division (/), and parentheses can be used to change the order of operations.

11.Functions

Functions are pre-defined formulas in Excel that perform specific tasks. For instance, the SUM function calculates the total, and the AVERAGE function calculates the mean. The syntax is usually “FunctionName(Arguments).” For example, “=SUM(A1:A10)” calculates the total of numbers in cells A1 through A10. Excel provides a wide range of functions for tasks like mathematical calculations, text processing, date/time computation, and logical evaluation.

V. Data Sorting and Filtering

12.Sorting

You can sort data in ascending or descending order using the “Sort” button in the “Data” menu. Sorting can be based on one or multiple columns. For example, in an employee salary table, sorting salaries from highest to lowest quickly identifies the highest-paid employee.

13.Filtering

Filtering allows users to display or hide data based on specific criteria. After clicking the “Filter” button in the “Data” menu, dropdown arrows appear next to column headers. These arrows let you set filter conditions, such as displaying only numbers greater than a certain value or text containing specific keywords. For example, in a sales data table, you can filter by region to analyze sales data for a specific area.
