String Escaper & Unescaper

Instantly format raw text blocks by escaping special coding sequences, or revert escaped strings back to original plaintext structures. Optimized for developers working with HTML, JavaScript, JSON, SQL, or CSV cells.

When and Why to Escape Strings

String escaping is a foundational web security measure. Inserting raw unescaped inputs into data sinks leaves applications highly vulnerable to structural breakdowns or malicious script injections:

  • Cross-Site Scripting (XSS): Unescaped HTML tag inputs parsed by browsers can execute hostile scripts directly within user web sandboxes.
  • SQL Injections: Injecting unescaped quotes inside query syntax strings can rewrite database transaction commands entirely.
  • JSON Schema Errors: Forgetting to escape quote marks in string values breaks JSON serialization parser syntax trees completely.

Escape Format Standards

  • HTML Standard: Replaces tag delimiters (<, >, &) with safe entity references so markup displays visually without executing.
  • JS/JSON Standard: Interposes backslashes before control triggers (like \n or \") to preserve literal definitions within script constants.
  • SQL Standard: Doubles single quote delimiters (' to '') to neutralize data fields and safeguard database parameters.
  • CSV Standard: Encapsulates raw table rows containing commas or double quotes in bounding quotes to maintain structural integrity.

Frequently Asked Questions

What is string escaping?

String escaping is the process of converting special characters (like quotes, backslashes, or angled brackets) into safe representations (like HTML entities or backslash-escaped characters). This ensures characters are interpreted literally rather than triggering code execution or structure issues.

What formats does this tool support?

We support four core formats: HTML Entities (escapes tag characters for visual markup display), JavaScript/JSON String literals (escapes newlines, quotes, and backslashes), SQL parameters (escapes quotes for queries), and CSV cell values (formats cells with commas or quotes).

How does CSV escaping work?

If your text contains commas, double quotes, or newlines, CSV rules dictate wrapping the entire cell inside double quotes. Any pre-existing double quotes inside the string are escaped by doubling them (e.g. " becomes "").

Is my data secure?

Absolutely! Like all FlowStack Tools, the String Escaper runs 100% locally in your web browser. No text or string payload is ever transmitted over the internet or uploaded to any server.
