String Escaping 101: Preventing Syntax Errors and XSS

UtilToolkits2025-12-19

The Danger of Special Characters

In programming, characters like ", ', &, and < have special meanings. If you insert a string containing these characters into code without "escaping" them, the computer gets confused.

For example, var x = "User said "Hello""; causes a syntax error because the inner quotes break the string.

Safe Strings

Our String Escaper handles this automatically for multiple languages:

  • JSON: Escapes backslashes and quotes.
  • HTML: Converts special chars to entities to prevent XSS.
  • Java/JS: Escapes quotes and newlines.

Code safely. Escape your strings with the String Escaper.
