Whether you're just starting out or are a seasoned analyst, mastering Excel can significantly enhance your ability to turn raw data into actionable insights. Let’s explore how Excel can empower your data analysis journey!
The topics that would be discussed are:
1. Formulas
2. XLOOKUP and VLOOKUP
3. Conditional Formatting
4. Pivot Table in Excel
FORMULAS:
SUM:
Usage: Adds up a range of cells.
Example: =SUM(A1:A10)
AVERAGE:
Usage: Calculates the average of a range of cells.
Example: =AVERAGE(B1:B10)
COUNT:
Usage: Counts the number of cells that contain numbers.
Example: =COUNT(C1:C10)
COUNTA:
Usage: Counts the number of non-empty cells.
Example: =COUNTA(D1:D10)
MIN/MAX:
Usage: Finds the minimum or maximum value in a range.
Example: =MIN(E1:E10) or =MAX(F1:F10)
IF:
Usage: Performs a logical test and returns one value for a TRUE result and another for a FALSE result.
Example: =IF(G1>50, "Pass", "Fail")
CONCATENATE (or CONCAT):
Usage: Joins several text strings into one string.
Example: =CONCATENATE(A2, " ", B2)
TEXT:
Usage: Converts a value to text in a specified number format.
Example: =TEXT(A2, "dd-mm-yyyy")
LEFT/RIGHT/MID:
Usage: Extracts a substring from a string starting at the left, right, or a specific position.
Example: =LEFT(C2, 5) or =RIGHT(C2, 3) or =MID(C2, 2, 3)
SUMIF/SUMIFS:
Usage: Adds cells that meet one or more criteria.
Example: =SUMIF(D1:D10, ">50", E1:E10) or =SUMIFS(F1:F10, D1:D10, ">50", E1:E10, "<100")
COUNTIF/COUNTIFS:
Usage: Counts the number of cells that meet one or more criteria.
Example: =COUNTIF(D1:D10, "Pass") or =COUNTIFS(D1:D10, "Pass", E1:E10, ">60")
NETWORKDAYS:
Usage: Returns the number of whole workdays between two dates.
Example: =NETWORKDAYS(Q1, R1)
XLOOPUP and VLOOKUP:
XLOOKUP:
Usage: Searches a range or array, and returns an item corresponding to the first match it finds.
Example: =XLOOKUP(J1, A1:A10, B1:B10)
VLOOKUP:
Usage: Searches for a value in the first column of a range and returns a value in the same row from another column.
Example: =VLOOKUP(H2, A1:C10, 3, FALSE)
The above formulas are mainly used to search and return the required values from the data.
CONDITIONAL FORMATTING:
Conditional Formatting is a powerful feature in Excel that allows you to apply formatting to cells based on the values they contain. This makes it easier to visualize data, highlight important information, or identify trends and patterns at a glance.
Features:
Automatically highlight cells that meet certain criteria (e.g., cells with values greater than a specific number).
Use color scales or data bars to show trends or performance (e.g., sales growth over time).
Easily spot duplicate entries in a dataset.
Quickly find cells that contain errors or unexpected values.
Formatting Rules:
Highlight Cells Rules: This option allows you to format cells that meet specific criteria like greater than, less than, equal to, between, etc.
Top/Bottom Rules: This option formats the top or bottom values, percentages, etc.
Data Bars: Adds a bar within the cell to represent the value visually.
Color Scales: Applies a color gradient based on the cell values.
Icon Sets: Adds icons within cells based on their value.
Step by step guide for conditional formatting:
1. First, select the cells or range of cells where you want to apply conditional formatting.
2. Go to the Home tab on the Excel ribbon.
3. Choose the formatting rule.
4. After selecting a rule, define the criteria (e.g., format cells greater than 100) and choose the format (like cell color, text color, etc.).
Ex: Choose Highlight Cells Rules > Greater Than.
Enter 50 and select the formatting style (e.g., light red fill with dark red text).
Custom Conditional Formatting:
For more complex conditions, choose New Rule from the Conditional Formatting menu.
This option allows you to create custom rules using formulas. For instance, to highlight cells in column A that are greater than the average of the entire column, you would use:
Rule Type: Use a formula to determine which cells to format.
Formula: =A1>AVERAGE(A:A)
Choose your desired format and click OK.
If you need to edit or delete existing rules, click Manage Rules in the Conditional Formatting menu.
Here, you can see all rules applied to the selected range or the entire worksheet, make adjustments, and prioritize rules.
PIVOT TABLES:
Pivot Tables are one of Excel's most powerful features for data analysis. They allow you to quickly summarize, analyze, explore, and present large amounts of data in a flexible, interactive way.
Features:
Easily group and aggregate data (e.g., sum, average, count) without needing complex formulas.
Quickly spot patterns and trends by breaking down data into meaningful categories.
Rearrange data (pivot) to look at it from different perspectives without altering the original dataset.
Drill down into the details or aggregate at higher levels with a few clicks.
Step by Step guide to make a Pivot Table:
Step 1: Prepare Your Data
Organized Data: Ensure your data is in a tabular format with labeled columns (headers) and no blank rows or columns.
Consistent Data Types: Each column should contain the same type of data (e.g., numbers, dates, text).
Step 2: Select Your Data
Highlight the Range: Click and drag to select the range of data you want to include in your Pivot Table. Alternatively, click anywhere within your data range if it’s well-defined.
Step 3: Insert the Pivot Table
Go to the Insert Tab:
On the Excel ribbon, go to the Insert tab.
Select Pivot Table:
Click on PivotTable in the Tables group.
Choose Your Data:
In the dialog box, confirm the selected data range. You can adjust it if necessary.
Choose whether to place the Pivot Table in a new worksheet or in an existing one.
Click OK to create the Pivot Table. Excel will insert a blank Pivot Table and display the PivotTable Field List on the right.
Step 4: Build Your Pivot Table
Drag and Drop Fields:
Rows: Drag fields (column headers from your dataset) that you want to appear as rows in your Pivot Table to the Rows area.
Columns: Drag fields you want to appear as columns to the Columns area.
Values: Drag fields you want to aggregate (e.g., sum, count, average) to the Values area.
Filters: Drag fields to the Filters area to create a filter at the top of your Pivot Table, allowing you to refine the data that’s displayed.
Pivot Tables are indispensable for anyone working with data in Excel, offering flexibility, ease of use, and the ability to generate powerful insights quickly. By mastering Pivot Tables, you can transform how you analyze and present data in your work.
