What is SQL formatting?

SQL formatting is the process of converting messy SQL code into a well-structured, easy-to-read format. By adding proper indentation, line breaks, and spacing, the code becomes easier to understand and maintain. This improves code readability and helps teams maintain consistent coding standards.

Which database dialects are supported?

We support multiple mainstream database dialects including: MySQL, PostgreSQL, Oracle PL/SQL, SQL Server (T-SQL), SQLite, MariaDB, TiDB, BigQuery, and standard SQL. Each dialect has specific syntax recognition for optimal formatting results.

Will my SQL code be uploaded to a server?

No. All SQL formatting is processed locally in your browser using JavaScript. Your code never leaves your device, ensuring complete data privacy and security. This makes our tool safe for formatting sensitive database queries.

How do I customize formatting options?

You can customize formatting options in the settings panel: choose indent size (2 or 4 spaces, or tab), select keyword case (uppercase, lowercase, or preserve original), set lines between queries, and select your target database dialect for optimal results.

What is SQL minification used for?

SQL minification converts formatted SQL code into a single line by removing extra spaces and line breaks. This reduces code size for transmission and storage, making it useful for embedded systems, API calls, and scenarios where minimal size is required.

Will formatted SQL change execution results?

No. SQL formatting only changes the display format of the code (indentation, spacing, line breaks). It does not affect the SQL semantics or execution results. Your queries will produce identical results before and after formatting.

Can it handle large SQL files?

Yes. Our tool is built on a high-performance parsing engine that can handle large stored procedures, complex queries, and multi-statement scripts. The processing happens locally in your browser, so performance depends on your device capabilities.

Is this tool free to use?

Yes, SQL Formatter is completely free to use with no registration required, no ads, and no usage limits. You can format unlimited SQL code without any restrictions or hidden fees.
