A JSON string is a JSON object or array that has been serialized into plain text — often escaped with backslashes and wrapped in outer quotes. For example, "{\"name\":\"Alice\"}" is a JSON string. This tool parses such strings back into proper, readable JSON.
If your input starts and ends with double or single quotes, the tool automatically strips the outer quotes and unescapes the content — converting \" back to ", \n to newline, \t to tab, and \\ to \. The result is then parsed as JSON.
You can choose between Pretty (formatted with 2-space indentation — default) and Minified (compact, no whitespace). Select your preferred format before clicking Parse.
If the input cannot be parsed as valid JSON after unescaping, a clear error message is shown. Common issues include unescaped control characters (use \n for newlines, \t for tabs) or syntax errors in the JSON structure.
Yes. Simply paste your minified JSON (without outer quotes) and select Pretty as the output format. The tool will parse and reformat it with proper indentation instantly.
You can upload files up to 100MB. All processing happens in your browser — your data is never sent to any server. The parsed output can be downloaded as a data.json file.
