You will get I will build scalable Excel export system (500K+ rows) with Spring Boot
Project details
I will build a high-performance Excel export system that can handle from thousands to millions of rows without memory issues.
Most traditional Excel export solutions fail with large datasets due to high memory usage and OutOfMemory errors. I solve this problem using a streaming-based approach (SXSSF) combined with optimized backend processing.
With 15+ years of experience in Java and Spring Boot, I specialize in building scalable and stable data processing systems. This solution is designed for real production environments, not just small test cases.
What you will get:
• Stable Excel export for large datasets (100K ~ 1M+ rows)
• Memory-efficient streaming processing
• Fast file generation and download
• Secure file export (optional encryption)
• Easy integration with your existing Spring Boot system
This solution is ideal for:
• Admin dashboards
• Large data reporting systems
• E-commerce / finance data exports
• Any system requiring reliable Excel downloads
If you're struggling with slow or unstable Excel exports, I can provide a robust and production-ready solution.
