RamprakashReddy42/Data-analyzer ? reverse-engineered prompt

Build me a simple React app for analyzing files. I want a clean page where someone can upload a file, see basic details about it, and get useful summaries without needing to know anything technical.

It should handle common file types as much as possible, and if a file can’t be fully analyzed, show a friendly message instead of breaking. The app should display things like file name, type, size, last modified date, and any other easy to understand info that makes sense for the file. If it’s a text based file, show a preview and some basic stats like lines, words, and characters.

Make the UI look modern and easy to use, with a clear upload area and results section. Keep it responsive so it works well on mobile too. If you need to look up current React best practices or browser file handling details online, go ahead. Also add a few simple tests if that fits the project.
