What Is a JSON Validator?
A JSON validator checks whether a block of text is syntactically valid JSON — correctly matched brackets and quotes, properly comma-separated values, no trailing commas — and reports exactly what's wrong if it isn't.
It's the fastest way to confirm a hand-edited config file or a suspicious API response is actually parseable, before spending time debugging code that assumes it is.

टिप्स
Watch for Trailing Commas
A trailing comma after the last item in an object or array is a common cause of invalid JSON.
Use Double Quotes Only
JSON requires double quotes for strings and keys — single quotes are invalid.
