String escape workbench
Escape or unescape JSON, JavaScript, SQL, shell, CSV, or regex strings locally.
Browser-only processing; use a trusted device when input may contain secrets.
Format boundaries
Limits: input up to 256 KiB. JSON/JavaScript unescape expects a quoted string literal; SQL and shell unescape expect one single-quoted literal or token; CSV unescape expects one field, not a full row. Regex mode escapes literal text for pattern use and does not execute the pattern.
