Escape JSON String

Escape JSON String turns plain text into a valid JSON string literal. It escapes quotes, backslash, line breaks, tabs, and special characters so the string can be safely inserted into JSON payload.

The service can also unescape a JSON string and show plain text. Useful when building API requests, payloads, logs, configs, test data, and documentation manually, when Unexpected token errors come from unescaped quotes or line breaks.

Processing runs locally in your browser.
