Everything you wished JSON viewers had.

Designed for developers who live in API responses, logs and configs.

Tree on the left

A formatted, code‑style outline. Click a node and the grid jumps to it.

Spreadsheet grid

Arrays of objects become real tables with sticky headers and row pinning.

Per‑column filters

Filter rows by any column — case‑insensitive, instant, virtualized.

Search everything

Find keys or values across the entire document with one shortcut.

Built for speed

Virtualized rendering handles 10 MB documents without breaking a sweat.

100% local

Your JSON never leaves your browser. Nothing is uploaded, ever.

Live preview

Two panes. Zero friction.

A formatted tree on the left mirrors your JSON structure. The grid on the right renders any selected array as a real table — sortable, filterable, virtualized.
