Show HN: AnalysisXYZ – Browser-based CSV/Excel analyzer (privacy focused)

Hi HN,

I’m a 1st-year CS undergrad from India. I built AnalysisXYZ because I wanted a way to quickly audit and visualize CSV/Excel files without uploading them to cloud tools (like ChatGPT) due to privacy concerns.

The Tech: It’s a browser-based tool. The analysis engine runs entirely on the client side (your data never hits my server).

Features:

.)Instant Executive Summaries for CSV/XLSX/PDF.

.)Privacy-first architecture (zero data retention).

.)This is my first real SaaS project deployed to production. I’d love feedback on the parsing speed with larger datasets and any critiques on the UI.

(P.S. Be honest—if the UI breaks, tell me!)

>Client-Side Processing: Your data never leaves your device.

Meanwhile

  curl -X POST -F "file=@file.csv" https://www.analysisxyz.dev/upload
  # responses with report because processing is server-side afterall

Vibe coding for real. Claiming client-side and not even checking whether indeed this holds. (Though an API-driven report-as-a-service is kinda cool; few years ago will've even been a commercially-viable startup.)
