Beautify and style JSON data with configurable indentation and color themes
Beautifies JSON with 5 syntax themes for the output, configurable indentation, key sorting, bracket padding, and quote style (double vs single). Handles trailing commas gracefully, supports JS object literal and JSONP output formats, and includes a side-by-side diff view between original and beautified JSON.
Raw minified JSON from APIs or config files is unreadable, and different projects use different formatting conventions. This tool not only pretty-prints JSON but also transforms it between formats (JS object, JSONP) and themes it for readability.
API developers inspecting JSON responses, configuration file maintainers, and teams enforcing consistent JSON formatting across projects.
Paste raw JSON into the input area or upload a .json file
Select a theme from 5 options (e.g., light, dark, monokai, github, solarized)
Set indent size (2, 4 spaces or tabs), toggle bracket padding, and choose quote style (double or single)
Enable sort keys to alphabetically order all JSON keys
Select output format: JSON, JS Object Literal, or JSONP (with callback name input)
Toggle trailing commas on or off; use side-by-side view to compare original vs output
Input: '{"z":1,"a":2}' with sort keys and 2-space indent. Output: '{\n "a": 2,\n "z": 1\n}'Input: '{name:"test"}' with JS Object Literal mode. Output: '{name: "test"}' (unquoted keys if valid identifiers).Format, validate, and minify JSON data with syntax highlighting
