How to use this tool
Provide plain text for encoding and valid JSON for decoding. To restore escaped newlines unambiguously, include the surrounding double quotes required by a proper JSON string value.
Results and examples
Encoding hello produces the quoted JSON value "hello". A real line break is represented by a backslash-n escape inside JSON and can become a line break again when that string is decoded.
Limitations
- Bare escape text without JSON quotes may not be interpreted like a JSON string.
- Parsed numeric values are subject to JavaScript number precision.

Frequently asked questions
How is text represented in JSON?
Encoding hello produces the quoted JSON value "hello". A real line break is represented by a backslash-n escape inside JSON and can become a line break again when that string is decoded.
Does unquoted escape text work the same way?
Bare escape text without JSON quotes may not be interpreted like a JSON string. Parsed numeric values are subject to JavaScript number precision.
