Frequently asked questions
What gets escaped?
It depends on the format. Programming languages escape quotes, backslashes, line breaks and control characters. HTML and XML escape & < > and quotes. SQL doubles single quotes. Regex escapes characters like . * + ? and brackets. CSV wraps fields in quotes.
Should I include the surrounding quotes?
The result doesn't include them, so you can paste it between your own quotes. For example, use the JSON result inside double quotes.
What does escaping non-ASCII characters do?
It writes characters such as é and emoji as \uXXXX sequences, which is useful when a file or API only allows plain ASCII.
Can this protect against SQL injection?
No. Escaping isn't a safe way to build SQL. Always use parameterized queries in your code.
