SQL Escape / SQL Unescape Tool

SQL Escape & Unescape – Escape SQL String Online

Use this free SQL escape/unescape tool to safely escape SQL string values and reverse them when needed. Paste your input text, click a button, and the tool adds or removes the SQL special characters escape sequences so your queries stay valid and secure.

Whether you’re building ad-hoc queries, preparing sample code, or cleaning up logs, this page gives you a quick way to handle special characters in SQL strings without guessing where to put quotes and backslashes.

What the SQL Escape/Unescape Tool Does

The CodersTool SQL escape utility focuses on two operations:

• Escape SQL string – Add the proper backslashes or doubled quotes so your text can be safely inserted into an SQL string literal.
• Unescape SQL string – Take an already escaped value and turn it back into normal, human-readable text.

This is especially useful when dealing with strings that contain quotes, backslashes, or control characters that would otherwise break your SQL syntax.

Common SQL Special Characters to Escape

Depending on the database engine, typical characters that require sql special characters escape handling include:

• Single quotes in text, for example O'Reilly
• Backslashes in file paths or patterns
• Line breaks, tabs, and other control characters

Instead of manually doubling quotes or inserting escape sequences, you can let this tool handle the transformation for you.

How to Use the SQL Escape String Tool

1. Escape text for SQL

1. Paste your raw text into the input box.
2. Click the “Escape” option to run the sql special characters escape logic.
3. Copy the result and use it inside your SQL string literal or script.

2. Unescape SQL text

1. Paste an escaped SQL string (with doubled quotes or escape sequences) into the tool.
2. Select “Unescape” to convert it back into normal text.
3. Use the plain result in your UI, logs, or documentation.

Best Practices

• Use parameterized queries in production – While this tool helps with formatting, real applications should use parameterized queries or ORM frameworks to guard against SQL injection.
• Use this tool for demos and diagnostics – It’s ideal for snippets, debugging, and documentation where you quickly need to show a correctly escaped SQL string.
• Know your database flavor – Different databases have different escaping rules; always confirm which style your engine expects.

SQL Escape Example

Plain SQL Before:

SELECT column_name1,    column_name2 FROM table_name WHERE column_name1 = 'express'

Escape SQL After:

SELECT column_name1,\n   column_name2\nFROM table_name\nWHERE column_name1 = \'express\'\n
