All right, let’s get into understanding MS Excel.

1. Introduction to Excel

Definition

Microsoft Excel is a spreadsheet software developed by Microsoft that helps people store, organize, calculate, and analyze data using tables made of rows and columns.
It allows users to:

  • Perform calculations with formulas and functions
  • Sort and filter information
  • Create charts and graphs
  • Summarize data using tools like Pivot Tables

Simply put, Excel turns raw numbers into useful information that helps with decision-making.

Excel is a spreadsheet program made up of:

  • Rows – horizontal lines (1, 2, 3…)
  • Columns – vertical lines (A, B, C…)
  • Cells – where rows and columns meet (like A1, B2)

Each cell can contain:

  1. Text (Names, Categories)
  2. Numbers (Sales, Scores)
  3. Dates (1/1/2026, 02-11-2026)
  4. Formulas (calculations), among many others.

Rows, Columns & Cells

Example Dataset

Let’s say we have this simple sales dataset:

Date Product Quantity Price Total Sales
1/1/2026 Pen 10 15 150
1/2/2026 Book 5 70 350
2/3/2026 Pencil 7 25 175
1/4/2026 Rubber 3 10 30

_NOTE: In this table, the Total Sales column is calculated by multiplying Quantity × Price.

This kind of table is the starting point for data analysis.

Example Dataset

2. Excel Functions (Basic Calculations)

Functions are built-in formulas that help you perform calculations easily.

1. SUM – Add Numbers

Adds a range of numbers.

=SUM(C2:C5)

This adds all values from cell C2 to C5.

Use case: Total sales, total expenses, total quantity sold.

Sum Func

AVERAGE – Find the Mean

Calculates the average of numbers.

=AVERAGE(D2:D5)

Use case: Average score, average daily sales.

AVG Func

COUNT – Count Numbers

Counts how many cells contain numbers.

=COUNT(A2:A5)

Use case: Number of transactions recorded.

COUNTA – Count Non-Empty Cells

Counts cells that are not empty (text or numbers).

=COUNTA(B2:B5)

Use case: Number of customers or products listed.

IF – Logical Function

Performs a test and returns different results depending on the outcome.

=IF(C2>10, "High", "Low")

This checks if the value in C2 is greater than 10.
** Use case** Categorizing sales as High/Low, Pass/Fail.

If Func

3. Data Cleaning in Excel

Before analysis, data often needs cleaning.
Common cleaning tasks:

  • Removing duplicates Data -> Remove Duplicates
  • Sorting data Data -> Sort A to Z
  • Filtering data Data -> Filter

Dups, sort, filter

Filtering lets you view only certain data, like:

  • Only sales for “Pen.”
  • Only records from January

4. Pivot Tables (Powerful Data Summaries)

Pivot Tables help you summarize large data quickly without complex formulas.

You can answer questions like:

  • Total sales per product
  • Sales per month
  • Quantity sold by category

Steps to create a Pivot Table:

  1. Select your data
  2. Go to Insert -> PivotTable
  3. Choose where to place it
  4. Drag fields into Rows, Columns, and Values

Example:

  • Rows -> Product
  • Values -> Sum of Total Sales

Excel will automatically calculate total sales for each product.

Pivot Table

5. Charts in Excel

Charts help turn numbers into visuals that are easier to understand.

Common chart types:

  • Column Chart – Compares categories
  • Line Chart – Shows trends over time
  • Pie Chart – Shows proportions

How to insert a chart:

  1. Select your data
  2. Click Insert
  3. Choose a chart type

Example: Sales by product displayed as a column chart.

Chart

6. Dashboards in Excel

A dashboard is a single page that shows key insights using charts, numbers, and summaries.

A simple Excel dashboard might include:

  • Total Sales (big number)
  • Sales by Product (chart)
  • Sales by Month (line chart)
  • Top Product (text or card)

Dashboards help decision-makers understand performance quickly.

Tools used in dashboards:

  1. Pivot Tables
  2. Charts
  3. Slicers (interactive filters)

Dashboard

Conclusion

Excel is a powerful starting tool for data analytics because it helps you:

  • Organize data in tables
  • Perform calculations using functions
  • Clean and filter messy data
  • Summarize information with Pivot Tables
  • Visualize trends using charts
  • Build dashboards for reporting

Mastering Excel gives you a strong foundation before moving into advanced analytics tools like Power BI, Python, or SQL.

ALL THE BEST IN YOUR ANALYTICS JOURNEY!
