JSON Unescape Online: Free Tool for JSON String Unescaping & Auto-Detection

In modern web development and data processing, **JSON (JavaScript Object Notation)** is the standard format for data exchange. However, JSON data often contains escaped characters that need to be unescaped for proper processing and readability. Our **JSON unescape online** tool provides instant, accurate unescaping with intelligent auto-detection capabilities.

What is JSON Unescaping?

**JSON unescaping** is the process of converting escaped JSON strings back to their original form. JSON uses escape sequences to represent special characters, and unescaping converts these sequences back to their actual characters.

Common JSON Escape Sequences

**\"**: Double quote

**\\**: Backslash

**\/**: Forward slash

**\b**: Backspace

**\f**: Form feed

**\n**: Newline

**\r**: Carriage return

**\t**: Tab

**\uXXXX**: Unicode characters

Example of JSON Unescaping

**Escaped JSON**:

`"Hello \"World\"!\nThis is a test."`

**Unescaped JSON**:

`"Hello "World"!

This is a test."`
