JSON copied from a website can break even when it looked correct on the page. The copy operation may include smart quotes, hidden characters, line labels, extra comments or surrounding text that is not part of the JSON.
Paste the data into the JSON Formatter and Validator. If strange characters remain, clean the text with Remove Non-ASCII or simplify formatting before validating again.
Smart quotes are a common cause
JSON requires straight double quotes. Curly quotes copied from an article, chat or formatted document can make the whole object invalid.
Extra labels break the structure
Examples often include labels like “Request body:” or comments beside the JSON. Those lines are useful for humans, but they are not valid JSON.
Clean before you trust the data
Remove surrounding prose, normalize quotes and validate the smallest possible object. Then format the clean version and copy it into your tool or app.
