At HashStudioz Technologies, we helped an enterprise software client modernize their Excel-based workflows by integrating Microsoft Graph API, Azure Active Directory, and Excel Online. The client, who heavily depended on Excel for reporting and data operations, faced delays, data inconsistencies, and manual inefficiencies. Our tailored solution enabled real-time data interaction, automated reporting, and live dashboards — resulting in an 80% reduction in manual effort and significantly improved reporting accuracy.
“When you modernize Excel with APIs and automation, it becomes a live, intelligent business tool — not just a spreadsheet.” — Technical Lead, HashStudioz

The Challenge
A client approached us with a growing operational pain point: managing dynamic Excel workbooks as part of their reporting and automation workflows. They needed:
- Real-time access to update and read Excel files stored on OneDrive or SharePoint.
- The ability to trigger data updates programmatically.
- Seamless integration with internal tools without manual intervention.
The existing solutions required frequent downloading, editing, and uploading of Excel files — leading to data inconsistencies and wasted effort.
Our Solution
We implemented a robust solution powered by Microsoft Graph API for Excel — enabling direct, programmatic interaction with Excel workbooks hosted in the cloud.
Key Features Implemented:
- Read & Write Operations: Real-time cell-level manipulation of Excel workbooks.
- Automated Data Ingestion: Scheduled scripts to populate Excel with data from external systems (sales, inventory, finance, etc.).
- Dynamic Table Updates: Insert/update rows in named Excel tables via API.
- Formula Injection & Evaluation: Use Excel’s native engine to calculate results programmatically.
- Secure Access via Azure AD: Token-based OAuth 2.0 authentication for secure access.
- Visual Dashboards Auto-Synced with Excel: Built responsive dashboards that pull live data directly from Excel — eliminating the need for manual refreshes.
Tech Stack Highlights
- Microsoft Graph API (Excel endpoints)
- Azure Active Directory (App Registration & Token Handling)
- Node.js / Python (backend automation)
- React.js + Chart.js (for visual dashboards)
- Power Automate (workflow integration)
The Outcome
- Reduced manual Excel handling by 80%
- Improved reporting accuracy & real-time visibility
- Delivered auto-refresh dashboards that mirror Excel data live
- Strengthened the client’s data-driven decision-making process
