Free Online JSON Viewer

Use the JSON Viewer to validate JSON syntax, format or minify JSON, inspect nested objects and arrays in a collapsible tree, reveal whitespace, and unescape JSON strings. Processing runs in your browser so pasted data stays on your device.

What this tool helps with

  • Validate pasted JSON and find syntax errors quickly.
  • Format, minify, and inspect nested JSON with a collapsible tree view.
  • Reveal tabs, spaces, new lines, and escaped JSON strings when debugging API responses or logs.
