Just upgraded my JSON toolkit to handle files up to 100MB — finally smooth, no lag!

I just rolled out a major update to Format JSON Online. — my all-in-one JSON toolkit built for developers, data analysts, and anyone who works with large JSON files.

🚀 What’s New:
Until now, most online JSON tools crash or freeze with large files. But now, Format JSON Online supports files up to 100 MB — with smooth performance and without freeze.

• 📂 Convert between JSON ⇄ CSV, Excel, XML

• ⚙️ Compare & Merge JSON files visually

• 💬 Create APIs from your own data (super handy for mock testing)

• 💻 And there’s even a Chrome Extension if you live in the browser like me

• 🧠 AI JSON Generator – turn plain text into structured JSON

Question:
What other JSON or developer-related tools would you find really useful in a toolkit like this? I’m open to ideas for anything from advanced JSON processing tools.
