ABOUT JSON ESCAPE

This page provides a specialized tool for escaping JSON strings. JSON (JavaScript Object Notation) requires special characters to be escaped according to the JSON specification. In JSON, the following characters are reserved and must be escaped when used inside strings:

EscapeMeaningExample
\"Double quote"Say \"Hi\""
\\Backslash"Path: C:\\\\Users"
\/Forward slash (optional)"URL: https:\/\/example.com"
\bBackspace"Before\bAfter"
\fForm feed"Page 1\fPage 2"
\nNewline"Line 1\nLine 2"
\rCarriage return"Line 1\rLine 2"
\tTab"Column 1\tColumn 2"
\uXXXXUnicode (4 hex digits)"Unicode: \u0048\u0065\u006C\u006C\u006F"

Note: Unlike many programming languages, JSON does not support escaping single quotes (\'). In JSON, strings must be enclosed in double quotes, and single quotes can be used as-is within the string.

The JSON Escape tool helps you convert special characters into their JSON escaped form, making them safe for use in JSON data. This is particularly useful when working with JSON strings that contain newlines, tabs, quotes, or other special characters that need to be properly escaped according to the JSON specification.

As part of StringFlux, this tool can be chained with other operations for more complex transformations. For instance, you can escape a JSON string and then JSON-format it, or unescape JSON back to its original form. If you need to work with general strings (not just JSON), check out our String Escape Tool.

FAQ

What are common use cases for escaping JSON strings?

Escaping JSON strings is essential when embedding JSON data inside code, URLs, or other JSON structures to avoid syntax errors. It’s commonly used in API payloads, configuration files, and logging to ensure special characters (like quotes, newlines, tabs) are safely represented.

Does input have to be valid JSON? Can I JSON escape a string literal?

The input doesn't have to be a complete JSON object. You can escape any string literal, making it safe to embed inside JSON structures or send over APIs.

How do I know if my JSON string is properly escaped?

Properly escaped JSON replaces characters like newline, tab, and " with their escaped forms. To verify, you can run it through the JSON Unescape — if it converts back to same readable text correctly, it's properly escaped.

Can I see examples of JSON Escape?

Of course! Here are two examples:

Example 1

Input:

{"name":"Jackson","message":"Hello World!"}

Escaped Output:

{\"name\":\"Jackson\",\"message\":\"Hello World!\"}

Try shared example 1 of JSON Escape.

Example 2

Input:

Line 1
Line 2
Single quote ' is not escaped

Escaped Output:

Line 1\nLine 2\nSingle quote ' is not escaped

Try shared example 2 of JSON Escape.

These show how valid JSON objects or plain strings can be escaped for safe storage, transmission, or embedding.

Can I chain JSON Escape with other StringFlux tools?

Absolutely. After escaping a string, you can apply additional transformations like Base64 Encode, JSON Unescape, and more — all in one seamless flow within StringFlux.
