How to use this tool well
Use this page when a JSON API response, config file, webhook payload, or pasted log needs to be cleaned up before you copy it into code or documentation.
- Paste the raw JSON into the editor, then check whether the formatted output keeps the same keys and nested arrays.
- If parsing fails, start from the first highlighted character and look for missing quotes, trailing commas, or copied HTML entities.
- After formatting, collapse large arrays mentally by section so you can compare payload shape without losing the original data.
