How To Use Excel To Analyze Data
1. Input Data Into Excel Spreadsheets
Before we can analyze data in Excel, we need to firstly input data into a worksheet within Excel.
Microsoft Excel can handle a wide range of data types, including numeric data, text data, dates and many more. The two main type of files that Excel can handle are Excel Workspace (XLSX) and Comma-separated values (CSV).
To input data into Excel, follow these steps:
- Open the Excel application on your computer.
- Locate the worksheet where you want to input the data.
- Click on a cell where you want to begin inputting the data.
- Type the data into the cell.
- Press the Enter or Return key on your keyboard to input the data into the cell.
Alternatively, you can also input data into Excel by copying and pasting it from another source, such as a word processing document or a website.
To do this, highlight the data that you want to copy, press
Ctrl+C on your keyboard to copy it, click on the cell in Excel where you want to paste the data and press
Ctrl+V on your keyboard to paste it.
2. Organize your data into a clear and concise format
Organizing your data is an essential step in any data analysis in Excel. This involves ensuring that your data is clear, concise, and easy to work with.
This can help you to identify trends, patterns, and relationships within your data, and make more informed decisions.
Plus, organizing your data in Excel can make it easier for others to understand and work with, which can be especially useful in teams.
There are several steps you can take to organize your data in Excel:
- Sort your data: Sorting your data can make it easier to find specific records or analyze specific subsets of your data. You can sort your data by clicking on a column heading, and then selecting “Sort A to Z” or “Sort Z to A” from the drop-down menu. You can also sort your data by multiple columns, and you can customize the sort order to fit your specific needs.
- Create new columns: If your data is spread across multiple columns, you can create new columns to help organize it. For example, you might want to create a new column to calculate the total of a set of numbers, or you might want to create a new column to combine data from multiple cells. To create a new column, simply select the column to the right of where you want to insert the new column, and then click on the “Insert” tab in the ribbon and select “Insert Columns.”
- Split columns into multiple cells: If your data is contained in a single cell, but it contains multiple pieces of information (such as a full name that includes the first name, middle initial, and last name), you can split the cell into multiple cells to make it easier to work with. To split a cell, select the cell, and then click on the “Data” tab in the ribbon and select “Text to Columns.” This will open the Convert Text to Columns Wizard, which will guide you through the process of splitting the cell into multiple cells.
3. Clean your data
It is important to clean your data because it can help improve the accuracy and reliability of your analysis.
When your data is clean, you can be confident that it is free of errors and inconsistencies, which means that you can trust the results of your analysis. Additionally, clean data is easier to work with and manipulate, saving you time and effort when you analyze it.
To clean data in Excel, you can use a variety of tools and techniques. Here are some steps you can follow to clean your data:
- Remove any duplicate rows or columns from your data: You can do this by using the Remove Duplicates tool, which is located in the Data tab of the ribbon.
- Remove any blank cells or rows from your data: You can do this by selecting the cells or rows that you want to delete, and then pressing the Delete key on your keyboard.
- Check for and correct any inconsistencies in your data: For example, if some cells contain dates in one format (such as “mm/dd/yyyy”) and others contain dates in a different format (such as “dd/mm/yyyy”), you can use the Text to Columns tool to convert all the dates to a single format.
- Use the Find and Replace tool to replace any incorrect or outdated information in your data: For example, if you have a column containing city names, and some of the city names are spelled incorrectly, you can use Find and Replace to quickly correct the spelling.
- Use data validation rules to ensure that the data in your spreadsheet meets certain criteria: For example, you can use a data validation rule to ensure that all cells in a particular column contain a valid email address, or to ensure that all cells in a particular row contain a number within a certain range.

4. Use Pivot table to summarise big data
Pivot tables are a powerful tool for analyzing data in Excel. They allow you to quickly summarize and analyze large datasets, and they can be customized to show only the information that you’re interested in.
Here are some tips for using pivot tables to analyze data in Excel:
- Create a pivot table: To create a pivot table, first select the cells that contain your data, and then click on the “Insert” tab in the ribbon and select “Pivot Table.” This will open the Create PivotTable dialog box, where you can specify where you want to place the pivot table and which data you want to include.
- Choose which fields to include in the pivot table: Once you’ve created your pivot table, you can choose which fields to include in the pivot table. For example, you might want to include the date field in the pivot table’s rows, the product field in the columns, and the sales field in the values. This will create a pivot table that shows the total sales for each product on each date.
- Customize the pivot table: You can customize the pivot table to show only the information that you’re interested in. For example, you can filter the pivot table to show only data from a specific time period, or you can group the data by month or quarter to see trends over time. You can also change the way the data is summarized (for example, by summing the values instead of averaging them), and you can add calculated fields to the pivot table to perform more complex calculations.
Overall, pivot tables are a valuable tool for data analysis in Excel. They allow you to quickly summarize and analyze your data, and they can be customized to show only the information that you’re interested in. By using pivot tables, you can uncover trends and patterns in your data that might not be immediately obvious, and you can make more informed decisions based on your analysis.
5. Turn your data into graphs
Excel has powerful graphing and charting capabilities that allow you to create visual representations of your data. These visualizations can make it easier to understand and analyze your data, and they can help you uncover trends and patterns that might not be immediately obvious.
Here are some tips for using Excel’s graphing and charting functions to analyze data:
- Select the data to include in the graph or chart: To create a graph or chart in Excel, first select the cells that contain the data you want to include. This might be a single column of data, or it might be multiple columns or rows. It’s important to select the data carefully, as this will determine which parts of your data are included in the graph or chart.
- Choose the type of graph or chart: Once you’ve selected the data to include in the graph or chart, you can choose the type of graph or chart you want to create. Excel has a wide range of graph and chart types to choose from, including line graphs, bar charts, scatter plots, and pie charts. Each type of graph or chart is best suited to a specific type of data, so it’s important to choose the right one for your data.
- Customize the graph or chart: After you’ve created your graph or chart, you can customize it to show only the information that you’re interested in. For example, you can add titles, labels, and legends to the graph or chart to help clarify the data. You can also change the colors, fonts, and styles of the graph or chart to make it more visually appealing.
Overall, Excel’s graphing and charting capabilities are a valuable tool for data analysis. By creating visual representations of your data, you can make it easier to understand and analyze, and you can uncover trends and patterns that might not be immediately obvious.
By using Excel’s graphing and charting functions, you can make your data analysis more efficient and effective.
