JSON Formatter / Sorter

Format minified or messy JSON into a readable structure, with key sorting, custom indentation, and tolerant parsing for trailing commas.

Run now REST API / MCP Manifest

Sample input

{"b":2,"a":1,"list":[3,1,2]}

API / MCP call

curl -X POST https://cn.toolkit.fun/api/v1/t/json-pretty \
  -H "Authorization: Bearer tk_..." \
  -H "Content-Type: application/json" \
  -d '{"input":"...","params":{}}'

MCP server: https://cn.toolkit.fun/api/mcp

Usage and examples

Open the workbench, paste JSON, choose indent (2, 4 or Tab) and sort (否 = no, 是 = yes), then run. Sorting recursively orders object keys while preserving array order. Invalid JSON reports an error.

Example 1

Input

{"b":2,"a":1}

Parameters

{"indent":"2","sort":"是"}

{
  "a": 1,
  "b": 2
}

Shortest path for an agent

Read the manifest first, then call the same run contract used by the web UI. The input, output, permissions, and receipt stay consistent across REST and MCP.

Manifest: https://cn.toolkit.fun/api/v1/registry/tools/json-pretty/manifest
