JSON Editor

Use one page to inspect, validate, and clean JSON

If you often work with API responses, configuration files, or nested logs, this should be your starting point. Clean the JSON here first, then move on to CSV, Base64, or other follow-up tools.

Common use cases

•Check whether an API response contains syntax errors.
•Format minified JSON into a readable review-friendly structure.
•Inspect object and array shape before exporting to CSV.

Example: clean JSON before converting it

When you receive nested JSON, format it first so you can confirm the field layout before sending it to JSON to CSV.

Example input

{"project":"Tools View","members":[{"name":"Alice","role":"Frontend"}],"active":true}

Formatted result

{
  "project": "Tools View",
  "members": [
    {
      "name": "Alice",
      "role": "Frontend"
    }
  ],
  "active": true
}
