Basic Tips for Working with Data
Learn how Excel helps you organize, sort, filter, summarize, and visualize large amounts of information efficiently.
Lesson Notes
Read through the key concepts before you try the challenge.
Introduction
Excel workbooks are designed to store a large amount of information. Whether you are working with 20 rows or 20,000, Excel includes powerful tools to help you organize your data and quickly find what you need.
Instead of manually scanning thousands of cells, you can use built-in features like freezing panes, sorting, filtering, subtotals, tables, charts, and conditional formatting to work smarter.
Freezing Rows and Columns
When working with large datasets, header rows can scroll off the screen. Freezing panes keeps important rows or columns visible while you scroll.
This is especially useful for date headers, employee names, or product categories.
Freezing panes allows header rows to remain visible while scrolling.
Sorting Data
Sorting reorganizes your worksheet so that data appears in a specific order. You can sort alphabetically, numerically, by date, or even by color.
For example, you might sort a customer list by last name or sales data from highest to lowest.
Filtering Data
Filters allow you to narrow down a worksheet to display only the information that meets certain criteria.
Instead of deleting rows, filtering temporarily hides data that does not match your selection.
Filtering shows only rows that match selected criteria.
Summarizing Data with Subtotals
The Subtotal command automatically groups data and calculates totals for each category.
This is useful when analyzing grouped information such as sales by region or inventory by category.
Formatting Data as a Table
Formatting data as a table improves both appearance and functionality. Tables include built-in filtering and sorting, and they automatically expand when new data is added.
Excel includes predefined table styles that make formatting fast and consistent.
Visualizing Data with Charts
Large datasets can be difficult to interpret at a glance. Charts transform raw numbers into visual comparisons and trends.
Charts are useful for identifying patterns, growth, declines, and performance differences.
Conditional Formatting
Conditional formatting automatically changes the appearance of cells based on their values.
You can apply color scales, data bars, or icons to quickly highlight trends and outliers.
Using Find and Replace
When working with large worksheets, locating specific information can be time-consuming.
The Find feature searches your workbook instantly. Replace allows you to modify multiple instances of text at once.

Challenge
Apply what you've learned in this lesson.
Using a worksheet with at least 20 rows of data, complete the following:
- Freeze the top row so headers remain visible.
- Sort one column alphabetically or numerically.
- Apply a filter to display only specific rows.
- Format the dataset as a table.
- Create a chart to visualize one column of numeric data.
- Apply conditional formatting to highlight the highest values.
- Use Find and Replace to change one repeated value in the worksheet.
