Frequently Asked Questions

What is string escaping?

String escaping is the process of converting special characters in a string into escape sequences that can be safely used in code. For example, a newline character becomes '\n' in JavaScript, and a quote becomes '\"' to prevent breaking the string.

What escape types are supported?

The tool supports JavaScript (for JS strings), HTML (for HTML entities), JSON (for JSON strings), Regex (for regular expressions), and URL (for URL encoding). Each type handles escaping differently based on the context.

When should I use string escaping?

Use string escaping when you need to safely include special characters in code strings, HTML content, JSON data, regular expressions, or URLs. It prevents syntax errors and security issues like injection attacks.

Can I unescape strings?

Yes! Select 'Unescape' mode to convert escape sequences back to their original characters. This is useful when you have escaped strings and need to see the actual content.

Is the string escaper free to use?

Yes! Our string escaper is 100% free with no registration required, no usage limits, and no hidden fees. You can escape and unescape as many strings as you need for your development work.

Are my strings stored or tracked?

No, all string escaping happens locally in your browser. We don't store, save, or have access to any strings you escape or unescape. Your privacy is completely protected.

What's the difference between escape types?

JavaScript escaping handles quotes, newlines, and special characters for JS strings. HTML escaping converts characters to HTML entities. JSON escaping follows JSON string rules. Regex escaping escapes regex special characters. URL escaping uses URL encoding.

When should I use JavaScript escaping?

Use JavaScript escaping when you need to safely include strings in JavaScript code, especially when the string contains quotes, newlines, or special characters that could break the code syntax.

When should I use HTML escaping?

Use HTML escaping when you need to display user input or dynamic content in HTML without it being interpreted as HTML tags. This prevents XSS attacks and ensures proper rendering.

Can I escape strings for regex patterns?

Yes! Select 'Regex' escape type to escape special regex characters like parentheses, brackets, dots, and asterisks. This is useful when you want to search for literal strings in regex patterns.

How do I unescape a string?

Select 'Unescape' mode and choose the appropriate escape type. Paste your escaped string and the tool will convert escape sequences back to their original characters. This is useful for debugging or reading escaped strings.
