Stringify and unstringify JSON online with our free JSON stringify tool. Convert JSON objects to escaped string representations for embedding in code, APIs, and environment variables, or parse stringified JSON back into readable objects. Handles nested escaping, special characters, and round-trip conversion without data loss.
Try Convert All - paste JSON once, see TypeScript, Go, YAML, and 15 more formats instantly.
To stringify: paste a JSON object to wrap it in quotes with character escaping. To unstringify: paste a stringified JSON to convert it back to a readable object.
Use the mode switch to choose the conversion direction. Stringify wraps your JSON in quotes. Unstringify removes the outer quotes and resolves escape sequences.
Click Copy to place the stringified or parsed JSON on your clipboard, ready for embedding in code, API requests, or environment variables.
JSON.stringify converts a JavaScript object into its JSON string representation. When applied to a JSON value, it produces an escaped string wrapped in double quotes. This is useful for embedding JSON inside another string context.
You need stringified JSON when embedding it in a string field of another JSON document, setting environment variables, writing JSON to log messages, or passing JSON as a string parameter in API calls.
Paste the stringified JSON (a string with escape sequences like \n and \") into the tool and select Unstringify mode. The tool removes the outer quotes, resolves all escape sequences, and displays the original JSON object.
They are closely related. Stringify wraps the entire JSON in quotes and escapes internal special characters, producing a single string value. Escape only processes the special characters without necessarily adding outer quotes. This tool supports both behaviors.
