How it works

About this tool

This free online JSON escape tool converts plain text into a safely escaped JSON string body. Quotes, backslashes, tabs, and newlines become their JSON escape sequences so you can drop the result into a string field without breaking the document.

Paste text on the left — including multi-line snippets, log lines, and Windows paths — and the escaped output appears on the right as you type. Copy or download the result when you are done.

Escape encodes the characters inside a JSON string. If you already have a full JSON document and need a quoted string literal of the whole value, use the JSON Stringify tool instead.

Escape runs entirely client-side. Nothing is uploaded, which makes the tool safe for passwords, tokens, and other sensitive strings.

JSON Toolbox processes all data locally in the browser. Nothing is uploaded to a server.

Common questions

Frequently asked questions

How do I escape JSON online?
Paste any text into the input editor. Quotes, backslashes, tabs, newlines, and other control characters are escaped automatically so the result is safe to place inside a JSON string.
Which characters are escaped?
Double quotes (\"), backslashes (\\), and control characters such as tab (\t), newline (\n), carriage return (\r), and other Unicode escapes required by the JSON string rules.
Do I need valid JSON as input?
No. This tool escapes arbitrary text. If you already have a JSON document and want a full string literal (with surrounding quotes), use the JSON Stringify tool instead.
Is escaping done in the browser?
Yes. Escaping uses the native JSON string encoder in your browser. Your text is never uploaded or stored.
