SQL Escape Unescape Tool for SQL String Literals Online
The SQL Escape Unescape tool converts SQL text between escaped and unescaped forms. By default, it doubles single quotes for ANSI, PostgreSQL, and SQL Server conventions; MySQL mode uses backslash escapes. Choose escape or unescape to apply or reverse the selected behavior. Use the result for display and learning, not as a defense against SQL injection.
SQL Escape Unescape is a browser-based tool for escaping and unescaping SQL string literals. It helps developers and DevOps engineers change how SQL text represents quote characters, whether they are preparing a readable example or inspecting an already escaped string. The tool supports a default quote-doubling behavior and a MySQL mode that uses backslash escapes.
By default, the tool doubles single quotes, following the conventions described for ANSI, PostgreSQL, and SQL Server. MySQL mode uses backslash escapes instead. Choose whether to escape or unescape the input to apply or reverse the selected behavior. PostgreSQL E'' is also identified among the SQL conventions supported by the tool. These behaviors change the representation of the text; they do not make a query safe to execute.
SQL string literals represent text within SQL statements, and different SQL dialects use different escaping conventions. Converting between escaped and unescaped text can make a literal easier to read, help when embedding a string inside another string, or support documentation and learning. The right representation depends on the SQL dialect and the task. Parameterized queries are the correct defense against SQL injection; this tool is for display and learning only.
The tool runs entirely in your browser. Your input is processed on your own device and is not uploaded, stored, or sent to a server. It works offline once the page has loaded, so you can continue using it without a connection. SQL Escape Unescape is useful for developers and DevOps engineers who need a quick way to inspect or transform SQL text while keeping dialect conventions in mind.
Step 1: Paste or drop your SQL text into the tool. The input can include a string you want to escape or an escaped string you want to read.
Step 2: Choose whether to escape or unescape the text. Escaping applies the selected convention, while unescaping reverses it.
Step 3: Use the default quote-doubling behavior or MySQL mode, which uses backslash escapes. The default is described for ANSI, PostgreSQL, and SQL Server.
Step 4: Review the result, then copy it for your intended display, learning, or development task.
Use case: Embed an SQL string inside another SQL string without breaking the quoting. Escaping helps make the quote characters visible in the intended representation.
Use case: Read a densely escaped string by turning its escapes back into characters. This can help when inspecting SQL text copied from another source.
Use case: Prepare a literal for pasting into source code or a development example. Check that the convention matches the SQL dialect you are working with.
Use case: Compare quote handling across ANSI, PostgreSQL, SQL Server, and MySQL conventions. Switching between the default behavior and MySQL mode helps you inspect the different escaping styles.
Use case: Create clearer SQL examples for documentation or learning materials. Escaping and unescaping lets you show how a string is represented without manually editing each quote.
Use case: Review an escaped SQL string while troubleshooting text handling in a development workflow. Unescaping can make the content easier to read, but it does not validate a query.
