Smart Input Tool

Auto-detect JSON, Base64, JWT, or URL and route to decoded/formatted output

How Smart Input detection works

  1. Paste any payload (JSON, JWT, URL, Base64).
  2. The tool auto-detects the most likely type.
  3. It outputs a decoded/formatted representation ready to inspect or copy.

Ideal when debugging unknown payloads from logs, webhooks, or query params.
