If you're working with a large JSON file (~30 MB), here are a few effective methods depending on your environment:
For medium to large files that aren’t massive (~30MB), I recommend:
Minimal, ad-free, and works completely in-browser.
No server upload – uses Web Workers for performance.
Supports minify, format, and validate.
Can handle fairly large files if your browser has enough memory.
⚠️ Tip: Chrome or Firefox will perform better than Safari for large data in-browser.
