Questions & answers
Do I keep the surrounding quotes?
Yes. Escape produces a complete JSON string literal. Unescape expects those outer double quotes and rejects unquoted text or other JSON types.
Is JavaScript eval used?
No. The existing JSON syntax parser decodes strings without evaluating code. JavaScript single quotes, comments and expressions are not accepted.
Can I escape a JSON document?
The source is treated as text, so escaping a whole document produces one string containing that document. Use JSON Formatter if you want to format the object itself.
What limits apply?
Up to 250,000 source characters and 1,500,000 output characters. Newlines, tabs, quotes, backslashes and Unicode are handled; U+2028 and U+2029 are explicitly escaped.
