How to escape double quotes in JSON

In JSON, if you need to use double quotes inside a string, you must use a backslash () to escape them. This is because JSON uses double quotes to denote the start and end of strings, so unescaped double quotes inside strings will cause parsing errors.

For example, if you want to represent the following in a JSON string:

He said, "Hello, World!"

You need to write it in JSON as:

json
"He said, \"Hello, World!\""

Here, \" represents a literal double quote character, not the end of the string.

Here is an example of a JSON object that contains a key-value pair with escaped double quotes:

json
{
  "greeting": "He said, \"Hello, World!\""
}

In this example, the value for the greeting key contains an escaped double quote, which ensures the entire JSON object is correctly formatted and can be parsed properly.
