Excel Data Dashboard & Analysis
Created a professional Microsoft Excel dashboard to organize, analyze, and present data in a clear and easy-to-understand format. The project includes structured data, visual charts, key metrics, and a clean dashboard layout designed to help users quickly understand important information and make better decisions.
This project demonstrates my skills in Microsoft Excel, data organization, data analysis, formatting, and dashboard creation.

HR Analytics Dashboard | Power BI
Project Overview
I built an interactive HR Analytics Dashboard in Power BI to transform employee data into meaningful workforce insights and support HR-focused decision-making.
The project covered the complete dashboard development process — from understanding and preparing the dataset to creating KPIs, developing interactive visuals, designing a custom wireframe, and building the final dashboard.
Rather than directly copying the layout from the learning tutorial I followed, I first created my own wireframe and used it as the blueprint for the final dashboard.
Tools & Skills Used
Tools:
Power BI | Power Query | DAX | Excel/CSV
Skills:
Data Cleaning | Data Transformation | Data Analysis | Data Visualization | KPI Development | Dashboard Design | DAX Measures | Data Storytelling | Business Intelligence
What I Built
The dashboard provides an overview of employee demographics, workforce composition, employee attrition, salary levels, job roles, experience, and job satisfaction.
Key KPIs include:
Total Employees
Active Employees
Attrition Count
Attrition Rate
Average Age
Average Experience
The dashboard also analyzes:
Attrition by Department
Attrition by Gender
Attrition by Age Group
Attrition by Salary Slab
Attrition by Years of Experience
Job Role and Job Satisfaction
Employee distribution across departments
The final dashboard contains 1.42K employees, 1.19K active employees, 231 attritions, and a 16.3% attrition rate based on the cleaned dataset used for the project.
Data Preparation & Power Query
One of the first things I learned from this project was that importing a dataset into Power BI does not mean the data is automatically ready for analysis.
I used Power Query to inspect and prepare the dataset before building the dashboard.
I checked the data for empty values and removed unnecessary rows. I also used Group By and Count Rows on Employee ID to investigate whether employee records appeared more than once.
This was particularly useful because I initially did not understand why the tutorial was grouping Employee IDs.
I learned that grouping an ID and counting rows can be used as a duplicate-checking technique. Filtering the count so that it does not equal 1 helps identify IDs that appear more than once and therefore require further investigation.
This helped me understand the difference between simply following a Power Query step and understanding why that step is being performed.
DAX & KPI Development
I created measures to calculate the key HR metrics used throughout the dashboard.
One of the concepts that stood out to me was Active Employees.
The dataset contains an Attrition field indicating whether an employee left the organization.
Therefore:
Attrition = Yes → employee has left
Attrition = No → employee is considered active
To calculate Active Employees, I used the employee count together with an Attrition = No filter.
This helped me understand how a column that does not directly contain the metric I need can still be used to create a meaningful KPI.
I also worked with measures for Attrition Count, Attrition Rate, Average Age, and Average Experience.
Dashboard Design
Before developing the visuals, I created a custom wireframe in my preferred design tool.
I wanted the final dashboard to have its own visual identity rather than replicate the layout of the tutorial.
I chose a purple, white, and ash/gray color palette and structured the dashboard around six KPI cards followed by analytical sections for departments, attrition, salary, age, experience, and job satisfaction.
The wireframe helped me plan the visual hierarchy, spacing, and placement of each component before recreating the design in Power BI.
This was an important part of the project because it reinforced the value of planning the user experience before building the actual dashboard.
Challenges & What I Learned
One of the biggest learning moments was understanding Attrition and how it can be used to derive other HR metrics.
Initially, I questioned why the Employee Count needed to be filtered using the Attrition column when creating the Active Employee KPI.
Understanding that Attrition = No represents employees who have not left the organization made the calculation much clearer.
I also learned more about Power BI's sorting behavior.
For example, the salary slab visual was sorted by Attrition Count in descending order, rather than by the salary categories themselves. This meant the salary slab with the highest attrition appeared first.
Understanding this helped me realize that sorting is not simply a formatting decision — it can change what information a chart emphasizes.
Another important lesson was understanding the difference between data cleaning and data validation. Finding duplicate or empty records does not automatically mean they should be deleted. The analyst needs to understand why the records exist and whether removing them is appropriate.
Outcome
This project strengthened my practical skills in:
Power BI | Power Query | DAX | Data Cleaning | Data Analysis | Data Visualization | Dashboard Design | Business Intelligence
More importantly, it helped me move beyond simply building charts and start thinking about the reason behind each transformation, calculation, and visualization.
The project reinforced my approach of:
Understand → Clean → Validate → Analyze → Visualize → Communicate
I’m continuing to build projects that demonstrate not only my technical skills, but also my ability to turn raw data into clear and useful business insights.
Learning Credit
This project was inspired by a Power BI HR Analytics tutorial that I followed as a hands-on learning exercise, while designing my own wireframe and dashboard layout.
This is a retail sales and profit dashboard I built from scratch to turn complex spreadsheet data into easy-to-read visuals. The main goal of this project was to make a messy dataset meaningful so a business owner can instantly check how their store is performing.
Here is how I worked on this project:
Data Cleaning: I went through the entire raw file in Excel, filtered out bad entries, and organized the rows to make sure the dashboard numbers are completely accurate.
KPI Tracking: I used Excel formulas to pull out core business metrics, such as total revenue, total orders, and the overall profit margin (12.47%).
Designing Charts: I set up clean visuals to show key trends, like sales by shipping modes, customer segments, and a breakdown of top-performing products.
I also added dynamic slicers, so you can click on any region or year and the whole screen updates automatically. I handled this entire project manually from start to finish.
Tools used: Advanced Excel (Pivot Tables, Slicers, Formulas, Dashboard Design)
