About This Tool
Documentation
What does this tool do?
A JavaScript string sanitizer that escapes quotation marks (`"`, `'`), backslashes (`\`), newlines (`\n`), tabs (`\t`), template literal variables (`\${...}`), and non-ASCII unicode characters (`\uXXXX` / `\xXX`) for safe embedding into JS code or script evaluation tags.
When should you use it?
Use this tool when embedding dynamic strings into JavaScript variables, building code generators, avoiding syntax errors caused by unescaped quotes, or sanitizing JSON strings for eval contexts.
