JSON Toolbox

Full online version (30+ JSON tools): https://jsontoolbox.cc Chinese docs: README.zh.md

View JSON in Obsidian as a collapsible rich tree with inline previews for images, colors, links, timestamps, JWTs, Base64 and more — then format, validate, convert to YAML, or turn it into a table.

Features

• Reading-mode auto-render: json / yaml code blocks turn into a collapsible rich tree automatically; arrays of objects render as a table.
• 14 inline preview kinds: image, color swatch, clickable URL, email, audio, video, PDF, timestamp, JWT, Base64 (incl. inline images), UUID, IP, Markdown, regex.
• Keep original source: the original JSON / YAML is preserved in a collapsible section under every preview.
• 5 commands: Open JSON Viewer · Format JSON · Validate JSON · JSON ↔ YAML · JSON → Table/CSV.
• Fully local: parsing, formatting and conversion run inside your vault. No telemetry, no accounts, no cloud sync.
• 6 settings toggles, localized to your Obsidian language (Chinese / English).

Example

Copy the block below into a json code block in reading mode to see the rich tree, the array-of-objects table, and every inline preview (color, image, link, email, media, timestamp, JWT, Base64, UUID, IP, Markdown, regex):

Commands

Command	What it does
Open JSON Viewer	View selected JSON as a collapsible rich tree with inline previews
Format JSON	Pretty-print selected JSON (2-space indent)
Validate JSON	Validate selected JSON and locate the error
JSON ↔ YAML	Convert selection between JSON and YAML (auto-detects direction)
JSON → Table/CSV	Turn a JSON array/object into a table

Inline previews

Automatically detected on leaf values: color, image, audio, video, pdf, url, email, timestamp, jwt, base64, uuid, ip, markdown, regex.

Settings

The settings tab offers 6 toggles:

1. Auto-render in reading mode
2. Arrays of objects as table
3. Inline media previews
4. Expand tree by default
5. Keep original source
6. Sync fence language on convert

Labels follow your Obsidian interface language (Chinese / English); command names stay in English.

Privacy

All processing (parsing, formatting, validation, conversion) happens locally — no telemetry, no accounts, no cloud sync.

One exception: inline media previews (image / audio / video / PDF) fetch the remote URL found in your JSON in order to render the preview. Nothing is uploaded — the URL is only fetched to render the preview.
