Loading the editor only when it is ready

Guided overview
Learn the formatter layout in one glance.
The helper tags below sit next to the important UI elements so the workspace explains itself as you scan the page.
Paste JSON

Drop in a payload

Start by pasting JSON into the editor. Each tab keeps its own state, so you can compare multiple payloads side by side.

Use actions

Run formatter tools

Use the toolbar to format, minify, validate, sort keys, or convert JSON without leaving the page.

Check status

Read the footer signal

The status bar shows whether changes are saved and reminds you that processing stays local in your browser.

Short version: paste JSON, use the toolbar, then check the result and status bar.

If you want more detail, the docs link below opens the JSON help center.
