› About this tool · FAQ

Escape and unescape strings for various programming languages and formats including JavaScript, JSON, HTML, XML, CSS, SQL, RegEx, URL, CSV, and Python.

What's the difference between JavaScript and JSON escaping?

JavaScript and JSON escaping are very similar, but JSON is more strict. Both handle quotes, backslashes, and control characters the same way. The tool treats them identically for practical purposes.

When should I escape Unicode characters?

Enable Unicode escaping when you need ASCII-only output or when working with systems that don't handle Unicode well. Otherwise, leave it disabled for better readability.

Why does my CSV text get wrapped in quotes?

CSV escaping adds quotes around text that contains commas, quotes, or line breaks. This is the standard CSV format to preserve the data structure.

Can I unescape text that wasn't escaped by this tool?

Yes, the unescape function works with any properly escaped text, regardless of which tool created it. However, malformed escape sequences may not process correctly.

What does "preserve line breaks" do?

When enabled, actual line breaks in your text are maintained. When disabled, they are converted to escape sequences like \n.
