A fast, private way to escape string online
When writing code or formatting data, special characters can easily break your syntax. A stray quote mark in a JSON payload, an unescaped newline in a JavaScript variable, or an unhandled comma in a CSV file can cause parsing errors or even security vulnerabilities.
This tool provides a quick way to safely encode and decode text for various programming contexts. Whether you need a reliable json escape utility, or a way to prepare literal strings for database queries, everything updates instantly as you type. Because the conversion runs entirely in your web browser, your data remains strictly private. No text is ever sent to a server, making it safe for proprietary code, database contents, and sensitive API payloads.
Supported formats and rules
Different languages and data formats have different rules for what constitutes a special character and how it should be neutralized. This tool supports five common formats:
JSON: JSON requires strict double quotes for strings, and special characters like newlines, tabs, and internal quotes must be preceded by a backslash. The tool uses standard JSON stringification to ensure 100% compliant output. If you have an API response containing a stringified payload, you can easily unescape json string data back into readable text. For formatting the resulting JSON, you can use the JSON Formatter.
JavaScript: While similar to JSON, javascript string escape rules are slightly broader. This tool prepares strings to be safely embedded inside single quotes, double quotes, or template literals (backticks). It escapes single quotes ('), backticks (`), and template literal expressions (${). When unescaping, it resolves standard escapes (\n, \t), hex codes (\x20), octal sequences, and unicode code points (\u00A9 or \u{1F600}).
SQL: Database queries frequently fail due to unhandled quotes in user input. The sql escape single quote feature uses the standard SQL convention of doubling single quotes (turning ' into ''). This allows you to safely insert names like "O'Connor" or text containing apostrophes without breaking the INSERT or UPDATE statement syntax.
CSV: Comma-Separated Values rely on commas to separate columns and newlines to separate rows. If your actual data contains commas, newlines, or leading/trailing spaces, the tool wraps the entire string in double quotes. If the text itself contains double quotes, they are escaped by doubling them (""), adhering strictly to RFC 4180 standards.
Regex: Regular expressions use characters like *, +, ?, [, and $ as operators. If you need to match a literal string that contains these characters (like a URL, a file path, or a mathematical equation), you must escape them. The Regex option automatically prefixes all regex meta-characters with a backslash so they are treated as literal text.
Common use cases
Embedding JSON in JSON: Sometimes APIs require a JSON object to be passed as a string value within another JSON object. You can write your inner JSON normally, paste it here, and copy the escaped version to paste into your main payload.
Generating SQL scripts: If you are manually writing a script to migrate data or insert a list of names and descriptions into a database, you can paste the raw text here to ensure all apostrophes and quotes are properly escaped before pasting them into your SQL editor.
Building dynamic Regex patterns: When building a search feature that allows users to search for exact phrases using regular expressions, you must escape their input first. You can use this tool to quickly check how a complex string should look when properly escaped for a regex engine.
Fixing broken data: If you receive a CSV file where a specific cell is breaking the layout because it contains unescaped line breaks or commas, you can paste the raw cell data here, escape it, and paste it back into your raw file.
Why escaping matters
Syntax collisions happen when the data you are trying to process contains the same characters used by the programming language to structure the code. If a parser expects a double quote to mark the end of a string, and it encounters a double quote inside your text, it will assume the string has ended. The text that follows will cause a syntax error.
Escaping acts as a signal to the parser. By adding an escape character (usually a backslash \), you tell the parser, "treat the next character as normal text, not as a command." Unescaping simply reverses this process, stripping away the backslashes and restoring the text to its original, readable form.
For other types of data encoding, you might also find the HTML Encode/Decode or URL Encode/Decode tools useful.
