JSON Viewer & Beautifier
Paste minified or messy JSON on the left, get a clean, properly indented view on the right. Useful for reading API responses, log entries, or copy-pasted JSON snippets.
How to use this tool
Paste your JSON into the input on the left. Minified, single-line, or messy indentation are all fine.
A nicely indented, 2-space formatted version appears on the right as you type.
Use the Copy button to grab the beautified JSON for documentation, sharing, or pasting into an editor.
For a richer experience (collapsible tree, table view, in-place editing), open the main editor — it includes the same beautifier plus a full tree explorer.
All formatting is local and instant.
Frequently asked questions
What indent size is used?
2 spaces by default, which is the most common convention. The main editor lets you switch to other indent sizes.
Does it preserve key order?
Yes. JSON object key order is preserved exactly as in the input. JavaScript engines preserve insertion order for string keys, and we rely on that.
How is this different from the main editor?
This page is a lightweight beautifier: paste, format, copy. The main editor adds a collapsible tree view, table view, side-by-side comparison, schema validation, jq, and format conversion.
Is my data uploaded?
No. Beautification runs entirely in your browser.
