<p><strong>jsonyo</strong> is a lightweight JSON toolkit that lives in wp-admin. Open it from <strong>Tools <span aria-hidden="true" class="wp-exclude-emoji">→</span> JSON Toolkit</strong> and you get a clean code-editor-style workbench for everything JSON.</p>
<p>It is especially useful when you are working with:</p>
<ul>
<li>REST API responses and endpoints</li>
<li>ACF exports and nested custom field payloads</li>
<li>theme.json, block editor config, and site settings</li>
<li>webhook payloads and internal JSON on staging sites</li>
</ul>
<p>Six modes, one panel:</p>
<ul>
<li><strong>Format</strong> — paste raw JSON, get a properly indented tree with syntax highlighting</li>
<li><strong>Validate</strong> — instant pass/fail with line + column for syntax errors</li>
<li><strong>Query</strong> — JSONPath ($.users[0].name, items[*].id, recursive ..key) over the parsed tree</li>
<li><strong>Diff</strong> — paste two JSON blocks, see added/removed/changed paths side-by-side</li>
<li><strong>Stats</strong> — counts of objects, arrays, strings, numbers, booleans, nulls + max depth</li>
<li><strong>Minify</strong> — strip whitespace, get one-line output ready to paste</li>
</ul>
<h4>Zero data leaves your browser</h4>
<p>Every operation runs entirely in your browser via JavaScript. No external API call, no analytics, no upload. We never see your JSON. This means jsonyo works on private/internal JSON, on disconnected staging sites, on WordPress installs behind firewalls.</p>
<h4>Why a wp-admin plugin and not just a website?</h4>
<p>If you live in wp-admin (debugging REST API responses, inspecting block editor JSON, working with custom field exports, tracing webhook payloads), having a JSON workbench one click away beats opening a tab to an external tool. Same engine, same Surgical aesthetic, same monospace clarity — but it’s already there when you need it.</p>
<h4>Free forever</h4>
<p>This plugin has no paid tier, no upsell, no “Pro” upgrade. It’s free, GPLv2, and stays that way. The goal is simple: give WordPress developers a fast, private JSON workbench where they already work.</p>
