Escape special characters in JSON strings or unescape them back to normal. Handles quotes, newlines, tabs, and other characters that need special treatment. Essential for safely including special characters in JSON strings.
The process is simple:
JSON strings can contain special characters like quotes, newlines, and tabs. These need to be escaped (converted to escape sequences like \", \n, \t) to be safely included in JSON without breaking the syntax. Escaping ensures your data is valid JSON, while unescaping converts those sequences back to readable characters.
It converts special characters to escape sequences so they can be safely included in JSON strings. For example, a quote becomes \" and a newline becomes \n.
Common ones include quotes ("), backslashes (\), newlines (\n), tabs (\t), and carriage returns (\r). These characters need special handling in JSON strings.
Unescaping converts escape sequences back to their original special characters. So \n becomes an actual newline, and \" becomes a quote.
You need escaping when your JSON strings contain special characters that would otherwise break the JSON syntax. Escaping makes these characters safe to include.
