I built a simple tool: Excel JSON with validation (free beta)

Hey everyone 👋

I often had to convert Excel tables into JSON configuration files — and I kept doing it manually, making mistakes all the time.

So I built a small tool:

JSON Automator

➡️ Convert Excel (.xlsx) → clean JSON

➡️ Optional config validation (required fields, ints, bools, URLs, duplicates)

➡️ No account, free (beta)

Why I built it

Many teams still keep configuration data in Excel.

But someone eventually has to rewrite everything into JSON — and mistakes happen easily.

I wanted something simple:

• upload Excel
• validate
• get JSON
• done.

I'd really appreciate feedback 🙏

If you try it:

• Did it help?
• Anything confusing?
• Any missing validation rules?
• Bugs or edge-cases?

Comments are welcome — it will help me decide what to build next.

Thanks for reading! 🚀
