Frequently Asked Questions
What characters does the HTML escaper handle?
It handles all standard special characters including <, >, &, ", and '. It converts them to their respective named entities for maximum compatibility.
Can I use this to fix 'broken' JSON?
Yes! If you have text that should be a JSON string but is missing escapes, the JSON mode will help you format it correctly. Conversely, the unescape mode will extract the raw text.
Is this tool safe for sensitive data?
Absolutely. All transformation logic is executed locally within your browser using JavaScript. No text is ever uploaded to our servers, ensuring your passwords or API keys stay private.
Does the SQL mode prevent SQL Injection?
The SQL escaper is a convenience tool for manual query preparation. While it handles basic escaping (like single quotes), you should always use parameterized queries and prepared statements in your production code for complete security.
