JSON escape

Type or paste any text, such as a JSON document, a template or a message over several lines, and see it as a JSON string below: in double quotes, with quotes, backslashes, line breaks and tabs escaped.

What is escaped

Double quotes become \"
Backslashes become \\
Line breaks and tabs become \n and \t
Other control characters become Unicode escapes

Letters such as é, and emoji, are kept as they are, which JSON allows.

JSON inside JSON

Some APIs and message queues expect a JSON document as a string inside another one. Minify the JSON first so the string stays short and on one line.

In code and commands

The result is valid JSON, and a valid string in JavaScript and many other languages, so it can go into source code, a test fixture, a curl command or an environment variable.

And back

Paste a JSON string anywhere in the Formatter, such as on the JSON unescape page, to see the text inside again.

Questions

How do I escape JSON for a string?

Paste the JSON: the escaped string appears below, ready to copy. Minify the JSON first for a one-line string.

Is my data uploaded anywhere?
