View My JSONSee it as UI

Online JSON workspace — view, edit, format, validate, compare, and visualize. Paste once, explore Cards, Table, Tree, Graph, Charts, or 3D. Pro syncs your JSON across devices.

View my JSON in one place: paste once, then format, validate, and read it as cards, a rich UI, a table, a tree, charts, or a 3D graph. Spot images, videos, colors, and dates instantly — or turn the document into a landing page. Compare two payloads without opening another JSON tool tab.

One workspace for every view

Cards, table, and tree stay free. Switch views — including Rich media previews — without leaving the document. Pro adds cloud sync across devices.

New · Cloud save & accounts

Sync your JSON across devices with Pro

Paste in the web app, sign in, and upgrade to Pro to sync JSON across devices — plus Charts, 3D, Compare, and Rich on Yearly and Lifetime. Cloud save is app-only; the browser extension does not sync with saved JSON.

Sign in when you are ready

Create an account with email or Google. Your profile stays with you; cloud sync unlocks with Pro.

Pro cloud JSON save

Every Pro plan syncs JSON to your account so you can open the same document on laptop, tablet, or phone.

Cloud save is in the web app

Saved JSON syncs in the View My JSON app after you sign in and upgrade. The Chrome extension only views JSON in browser tabs — it does not show or sync your cloud saves.

What Pro adds

  • Cloud JSON save across devices
  • Charts, 3D explorer, Compare, ad-free workspace
  • Yearly & Lifetime: Rich Discover + JSON Landing page

Browser extension

View JSON right where you find it

The free extension beautifies JSON in the browser tab you open — API responses and .json files. It is separate from Pro cloud save in the web app; nothing here syncs with your saved documents.

  • For browser JSON only — API responses and .json tabs, not your cloud-saved documents
  • Opens raw JSON tabs as Cards, Table, or Tree automatically
  • Side Panel mode keeps the page untouched while you explore
  • Advanced local tools — sort keys, flatten, download JSON, export CSV
  • Open Pro hands the current tab off to the web app (Rich, Landing, Charts, 3D, Graph, Compare) — it does not sync with cloud saves

  1. 1

    Add to Chrome

    Install free from the Chrome Web Store. Works in Edge too.

  2. 2

    Open any JSON tab

    Visit an API endpoint or .json file — it renders as UI instantly, on that page only.

  3. 3

    Need Pro views?

    Open Pro sends that tab’s JSON to the web app once. Cloud save lives in the app — the extension does not sync saved JSON.

Online JSON Viewer, Editor & Visualizer

View My JSON is an online JSON workspace — not only another formatter. Paste once to view, edit, format, validate, compare, and visualize JSON in your browser on viewmyjson.com. Looking for a free jsoneditor or onlinejsoneditor? Open the app to edit JSON online with format, validate, and visual views in one place.

Everything you need to work with JSON

Why View My JSON?

One JSON document. Multiple ways to understand it — Cards, Table, Tree, Graph, Charts, Compare, and 3D — with format and validate in the same session. That is the product difference versus single-purpose formatter or validator sites.

Your JSON stays in your browser

Core viewing, formatting, and validation run locally:

  1. Paste JSON
  2. Browser parses locally
  3. Render locally as UI
  4. No account required for free core tools

Tool categories

  • Viewing — Read nested JSON as Cards, Table, or Tree.
  • Editing — Paste, edit, upload, and fix payloads in one workspace.
  • Formatting — Pretty-print, beautify, minify — then keep exploring.
  • Validation — Catch syntax errors before you debug logic.
  • Compare — Diff two payloads path-by-path.
  • Visualization — Graph, charts, and 3D for structure you can see.

How to view my JSON online

Paste once. Format, validate, and explore in the same ViewMyJSON workspace — then compare when you need a JSON diff.

Open the app

  1. Paste, format & beautify

    Drop a file or paste a payload. Use View My JSON as your JSON formatter online — pretty-print or minify stays in the browser.

  2. Validate & view my JSON

    Run the JSON validator, then read the same document as cards, a table, or a tree. Sign in when you want an account — Pro unlocks cloud save, charts, and 3D.

  3. Compare, Rich & cloud sync

    Diff two payloads with Compare, explore Rich / Landing on Yearly+, or sync JSON across devices with Pro cloud save in the web app. The Chrome extension only views JSON tabs in the browser — it does not sync cloud saves.
