Regex Escape Unescape: Escape and Unescape Regex Text
Regex Escape Unescape converts regex text by escaping or removing backslashes before regex metacharacters. Choose a flavor: JavaScript also escapes /, while PCRE, Python, Java, and .NET do not. Character-class mode escapes only characters that are special inside […]. Use it to prepare literal regex text for another pattern or source code, or to make escaped text easier to read.
Regex Escape Unescape is a browser-based tool for escaping or unescaping regex metacharacters. Paste or drop regex text, choose an operation, and copy the result for use in a pattern or source code. The tool supports JavaScript, PCRE, Python, Java, and .NET, with a flavor selector to apply the relevant escaping behavior.
When escaping, the tool adds backslashes before regex metacharacters. JavaScript escaping includes /, while PCRE, Python, Java, and .NET do not escape it. Character-class mode applies a narrower rule: it escapes only the characters that are special inside […]. When you choose unescape, the tool removes the backslash before escaped metacharacters.
Regex syntax uses metacharacters to give symbols special meaning in a pattern, while escaped forms can represent those symbols literally. Escaping is useful when preparing regex text to embed inside another regex string or paste into source code. Unescaping can make a densely escaped string easier to read. The flavor selector and character-class mode help match the output to the context where the text will be used.
Regex Escape Unescape is free and runs entirely in your browser. Your input is processed on your device; it is not uploaded, stored, or sent to a server. Once the page has loaded, the tool works offline, so you can use it without an active connection. It is useful for developers and DevOps engineers who need to prepare, inspect, or reuse regex text across supported flavors.
Step 1: Paste or drop your regex text into the tool. Check the input before converting so you can compare it with the result.
Step 2: Choose whether to escape or unescape. Escaping adds backslashes before regex metacharacters; unescaping removes the backslash before escaped metacharacters.
Step 3: Select the regex flavor that matches your use case. JavaScript escapes / too, while PCRE, Python, Java, and .NET do not.
Step 4: Choose character-class mode when working with content inside […]. In this mode, only characters that are special inside a character class are escaped.
Step 5: Copy the result and use it in your pattern or source code. Review the output to confirm it matches the context where you plan to use it.
Use case: Embed regex text inside another regex string without leaving metacharacters unescaped. This helps preserve the intended literal characters.
Use case: Make a densely escaped string easier to read by unescaping it. The tool removes the backslash before escaped metacharacters.
Use case: Prepare regex text for pasting into source code. Choose the appropriate flavor, since JavaScript also escapes / while PCRE, Python, Java, and .NET do not.
Use case: Escape only the characters that are special inside a character class. Character-class mode is useful when preparing text for use inside […].
Use case: Review an existing escaped pattern during debugging. Unescaping can make the metacharacters easier to inspect.
Use case: Convert regex text between escaping conventions when working with JavaScript and other supported flavors. The flavor selector accounts for JavaScript's handling of /.
