Escape strings for JSON, JavaScript, CSS, XML, and regular expressions without hand-counting backslashes. The output is deterministic and the conversion runs in your browser.
Choose the syntax context before escaping. A string safe inside JSON is not automatically safe inside HTML, JavaScript source, a SQL query, or a regular expression.
Why String Escaping Is Critical
Quotes, backslashes, control characters, and newlines have syntax meaning. Leaving them raw can break a parser, terminate a string early, or turn data into executable syntax.
Escaping prevents syntax collisions. It does not validate business input or replace context-aware output encoding and parameterized database queries.
The 5 Developer Escape Tools You Need
- JSON Escape & Unescape ToolEscape raw text for JSON strings and unescape JSON string content without hand-counting backslashes.
- JavaScript String Escape & FormatterCreate JavaScript string literals with single quotes, double quotes, or template literals.
- SQL String Escape & Injection Prevention ToolInspect SQL string escaping while learning why prepared statements are the correct production defense.
- Regex Escape Tool - Match Literal StringsEscape regular-expression metacharacters so user input is matched literally.
- CSV Escape & Formatter ToolPrepare CSV fields with RFC 4180-compatible quotes, commas, newlines, and escaped internal quotes.
Escaping vs. Encoding vs. Hashing
Escaping makes literal data safe inside a particular syntax context.
Encoding changes representation for transport, such as Base64 or percent encoding.
Hashing creates a one-way digest. It is useful for integrity and password verification workflows, not for recovering the original string.
FAQ
Does escaping prevent all injection attacks?
No. Escaping is context-specific and easy to misuse. Use prepared statements for SQL and context-aware output encoding for HTML and JavaScript.
How do I unescape a string in Python or JavaScript?
Use the language parser or a context-specific decoder rather than chained replacements. This site can help inspect and convert the string before you place it in code.
