Which language should I select?

Choose the intended JSON, JavaScript or Java string rules. Their supported escapes differ; an escape accepted for JavaScript may be invalid for Java or JSON.

Should quotes be included?

Use include for a complete quoted string literal. Use content-only for escaped text without its surrounding quotes. The setting applies when escaping and unescaping.

Does this execute code?

No. The tool reads and transforms supported string literals without evaluating source code or running a program.

Common errors and limitations

Check for incomplete quoted literals, unsupported escapes and unescaped line breaks inside a literal. Match the selected language and quote setting to the input.
