About This Tool
This tool beautifies or minifies JSON, validates its syntax, and points out precisely where an error occurs — useful for debugging API responses, config files, or hand-written JSON.
How to Use
- Paste JSON into the editor, or click "Upload" to load a .json file.
- Choose an indent style — 2 spaces, 4 spaces, or Tabs.
- Click "Format" to beautify it, or "Minify" to compress it onto one line.
- Click "Copy" or "Download" to save the result.
