About JSON Escape
JSON Escape is a free online tool that converts special characters in your text into their JSON-safe escape sequences. When building JSON strings manually or embedding text inside JSON payloads, characters like double quotes ("), backslashes (\), newlines, tabs, and control characters must be properly escaped to produce valid JSON. This tool handles all JSON escape characters defined in the RFC 8259 specification, including \" for double quotes, \\ for backslashes, \n for newlines, \t for tabs, \r for carriage returns, \b for backspace, \f for form feed, and \uXXXX for Unicode control characters. Everything runs 100% client-side in your browser — your data is never sent to any server. Developers, API engineers, and anyone working with JSON data use this tool to quickly escape JSON strings for embedding in code, API requests, configuration files, and database queries.
Frequently Asked Questions
What characters need to be escaped in JSON?
According to the JSON specification (RFC 8259), you must escape double quotes (\"), backslashes (\\), and all control characters (U+0000 through U+001F). This includes newlines (\n), tabs (\t), carriage returns (\r), backspace (\b), and form feed (\f). Forward slashes (/) may optionally be escaped as \/ but this is not required.
How do I escape double quotes in JSON?
To escape a double quote inside a JSON string, prefix it with a backslash: \". For example, the text He said "hello" becomes He said \"hello\" when properly escaped for use inside a JSON string value.
Does JSON need to be escaped?
Yes — any string value inside JSON that contains special characters must have those characters escaped. If you don't escape characters like quotes or backslashes, the JSON will be invalid and parsers like JSON.parse() will throw a syntax error. This tool automates the escaping process so you don't have to do it manually.
What is the difference between JSON escape and JSON unescape?
JSON escape converts raw text into a JSON-safe format by adding backslash escape sequences before special characters. JSON unescape does the reverse — it converts escaped sequences back into their original characters. Use escape when preparing text for JSON, and unescape when reading escaped JSON string data.
How do I escape a backslash in JSON?
A single backslash (\) in JSON must be escaped as a double backslash (\\). This is because the backslash is the escape character itself in JSON, so it needs to be escaped to be treated as a literal backslash.
Is my data safe when using this tool?
Absolutely. This JSON escape tool runs entirely in your browser using client-side JavaScript. Your text is never transmitted to any server, ensuring complete privacy and data security.
