Many operations, maintenance and construction teams still rely on Excel spreadsheets for reporting.
The problem isn't Excel itself.
The real challenge is transforming raw spreadsheet data into dashboards that managers can actually use to make decisions.
Most existing solutions require complex Excel formulas, Pivot Tables, Power BI or expensive BI platforms.
I wanted to build something much simpler.
A web application where someone could:
- Upload an Excel or CSV file
- Automatically calculate KPIs
- Generate interactive charts
- Export dashboards as PNG or PDF
without installing any software.
That's how Dashboard Tools Platform was born.
What Dashboard Tools Platform Does
Dashboard Tools Platform transforms Excel and CSV files into interactive operational dashboards directly in the browser.
The platform currently includes five dashboard generators:
- HH Dashboard Generator
- Maintenance KPI Dashboard
- Project KPI Dashboard
- Fuel Consumption Dashboard
- Workforce Productivity Dashboard
Everything runs completely on the client side.
No files are uploaded to any server.
This approach keeps data private while providing instant results.
Why I Chose Next.js
I built this project with Next.js because it provides an excellent developer experience while making it easy to build fast, SEO-friendly applications.
Some of the advantages were:
- File-based routing
- Great TypeScript support
- Server and Client Components
- Excellent performance
- Easy deployment on Vercel
The application is fully responsive and works on desktop, tablet and mobile devices.
Technologies Used
The project was built using:
- Next.js
- React
- TypeScript
- Tailwind CSS
- Recharts
- SheetJS (XLSX)
- PapaParse
- html-to-image
- jsPDF
Each library solves a specific problem, from spreadsheet parsing to chart visualization and exporting dashboards.
Dashboard Workflow
The workflow is intentionally simple.
- Upload an Excel or CSV file.
- Parse the dataset.
- Calculate KPIs automatically.
- Generate interactive charts.
- Export the dashboard as PNG or PDF.
No configuration is required.
Current Features
Excel & CSV Upload
Import operational data from Excel or CSV files.
KPI Cards
Automatically calculate operational metrics from uploaded data.
Examples include:
- Total Hours
- Total Cost
- Productivity
- Average Hours
- Fuel Efficiency
- Project Progress
Interactive Charts
Visualize operational data using:
- Bar Charts
- Pie Charts
- Line Charts
The charts automatically update based on the uploaded dataset.
PNG Export
Export dashboards as high-quality images suitable for reports or presentations.
PDF Export
Generate printable PDF dashboards with one click.
Client-side Processing
All calculations happen locally in the browser.
Your files never leave your computer.
Biggest Challenges
This project was much more challenging than it initially seemed.
Some of the most difficult parts included:
- Making charts fully responsive
- Exporting dashboards correctly to PDF
- Maintaining consistent layouts across desktop and mobile devices
- Parsing different Excel and CSV structures
- Creating reusable dashboard components that could support multiple dashboard types
Building reusable components became one of the biggest advantages as the platform continued to grow.
What I Learned
Developing Dashboard Tools Platform taught me several valuable lessons.
- Responsive dashboards require much more attention than traditional web pages.
- Exporting complex charts to PDF is not as straightforward as rendering HTML.
- Investing time in reusable components significantly speeds up future development.
- Good user experience is just as important as clean code.
Future Improvements
Some ideas I'm currently exploring include:
- Additional dashboard generators
- More operational KPI libraries
- Dashboard customization
- New export formats
- Dashboard templates
- More SEO guides
