Handle escape sequences for any context: JSON strings, JS literals, regex patterns, URL percent-encoding and HTML entities. Escape or unescape instantly in both directions.
Escape newlines, quotes, and backslashes before inserting dynamic text into JSON bodies or REST API request payloads. Prevents malformed JSON and hard-to-debug parse errors.

Building regex patterns safely
Escape special regex metacharacters like dots, parentheses, and dollar signs when constructing dynamic regular expressions from user input. Essential for search-and-replace and input validation logic.

Preparing SQL string literals
Sanitize strings before embedding them into SQL queries or stored procedures where dynamic values contain quotes or special characters. Reduces the risk of syntax errors in hand-crafted queries.
🌐
Escaping HTML content in JavaScript
Convert angle brackets, ampersands, and quotes to HTML entities when injecting text into innerHTML or template strings. Prevents XSS vulnerabilities and malformed markup.

Encoding control characters in log entries
Escape tab characters, carriage returns, and null bytes in log messages before writing to structured log pipelines. Makes log entries parseable by tools like Splunk, Elasticsearch, and Datadog.

Sanitizing user input for safe display
HTML-escape form submissions and user-generated content before rendering it on a page or passing it to a downstream service. A quick way to verify output encoding during code review or QA.
Select the JSON context, paste your raw string, and quotes, backslashes, and newlines are escaped into valid JSON string syntax immediately. Switch to unescape to reverse the process.
Does this tool support escaping for regex and URLs too?
Yes. Besides JSON, it handles JavaScript string literals, regex metacharacters, URL percent-encoding, and HTML entities, each selectable as its own context.
Is there a character limit for the string escape tool?
No practical limit for typical strings, log lines, or code snippets. The escaping and unescaping happen instantly regardless of input length.
What is the difference between escaping for JSON and for regex?
JSON escaping handles characters like quotes, backslashes, and newlines so a string is valid inside a JSON document, while regex escaping targets metacharacters like . and * so they are treated as literal text in a pattern instead of as pattern syntax.
