About the JavaScript Escape / Unescape
Embedding raw text, multi-line strings, or HTML into JavaScript variables requires escaping quotes, backslashes, and control characters to prevent syntax errors. Conversely, extracting raw text from escaped string literals requires unescaping. This JavaScript Escape / Unescape tool handles two-way conversions instantly.
This tool is useful for developers generating dynamic JavaScript code, passing string payloads into JSON templates, escaping user input for inline scripts, or decoding escaped logs. It supports Double Quotes ("), Single Quotes ('), Template Literals (` `), and JSON string escaping.
To use it, paste your text into the input box, choose your conversion mode ('Escape' or 'Unescape'), select the target quote format, and click 'Process Text'. The processed string appears immediately with one-click copy support.
For example, escaping a string containing quotes and line breaks converts it to safe escaped characters, making it safe to assign directly to a JS variable.
A common error when escaping strings manually is forgetting to escape the backslash ('\') character itself before other characters, which leads to corrupted escape sequences.
Tip: When working with ES6 template literals, select the 'Template Literal' mode to escape backticks and dollar-sign variable expressions ('${...}').
