How this tool works

Strict JSON only. JavaScript expressions and comments are rejected. Standard JSON.parse uses floating-point numbers; use strings for integers requiring more than 15–16 decimal digits of precision.

Inputs and results stay in this page’s memory until you leave or reset it. Downloads remain on your device. Review the result before using it in another application.
