A JSON string stored in a database, a log or a config file looks nothing like the text it represents — quotes are escaped, newlines appear as \n, and unicode hides inside \uXXXX. Unescape JSON String reverses all of that and shows you the real text.
Paste either a full quoted literal or just the escaped content, and the tool decodes every escape sequence — \", \\, \n, \t, \r and unicode — into the readable string underneath. It is the perfect companion to the Escape JSON String tool and runs entirely in your browser.
