Escape For The Syntax You Actually Need

String Escape / Unescape handles JSON, JavaScript, URL components, regular expressions, and CSV fields. Each mode follows different rules, so choosing the target syntax is part of the workflow.

Malformed Input Gets A Clear Error

Unescape modes catch malformed Unicode, hex, URL, JSON, and CSV escape sequences instead of guessing. Edit the source and retry until the output matches your intended string.

Not A Sanitizer

Escaping is not a universal security control. Use the output as a syntax helper, then apply context-aware validation or sanitization in the application where the string will be used.

FAQ

Which escape formats are supported?

Phase 5 supports JSON, JavaScript, URL component, regular expression, and CSV field escaping.

How are malformed escapes handled?

Malformed JSON, JavaScript, URL, or CSV escape sequences produce a clear local error so you can fix the input and retry.

Is escaping the same as sanitizing?

No. Escaping is syntax-specific text conversion. It does not make arbitrary content safe in every context.

Can I use it for Unicode and newlines?

Yes. JSON and JavaScript modes handle common quotes, backslashes, newlines, tabs, and Unicode escapes.

Is my string uploaded?

No. The string remains in browser memory.
