Master Data Upload for Existing APIs

The Challenge

The client had a modern API but their data was stuck in legacy Excel sheets. Manually entering this data was prone to human error and extremely slow.

The Solution

We created a middleware tool that parses Excel files, validates the data against the API's schema, and handles the upload process.

Key Features

• Drag & Drop Interface: Simple UI for non-technical users.
• Real-time Validation: Highlights errors in the Excel file before upload.
• Batch Processing: Uploads thousands of records in chunks to avoid timeouts.
• Rollback Capability: If an error occurs, the system can revert changes.

The Results

• Zero Data Entry Errors: Validation logic prevents bad data from entering the system.
• Hours Saved: What took days now takes minutes.
• User Independence: Non-technical staff can now manage data imports without IT support.

Technologies Used

To ensure scalability and security, we built this project using a modern tech stack:

• Frontend: React for a responsive UI
• Backend: Node.js and Express for efficient processing
• Data Processing: Specialized libraries for Excel parsing and API interfacing
