How to use it

What this SQL Formatter is for

Use this SQL Formatter when you need to clean up a query before debugging, reviewing a pull request, pasting SQL into documentation, or sharing an example with another backend developer.

The formatter runs in your browser. It does not upload queries, table names, comments, or example data to a server.

How to use it

Paste a SQL query, choose a keyword style, then click Format SQL. Use Minify SQL when you need a compact one-line version for logs, scripts, or small examples.

This is a lightweight formatter, not a full SQL parser. It handles common query shapes and protects quoted strings, but you should still run database-specific validation before shipping a query.

SQL Formatter questions

Does this SQL Formatter upload my query?

No. Formatting and minifying run locally in your browser, and the tool does not send SQL input to a server.

Can this formatter validate every SQL dialect?

No. It is a lightweight formatter for common SQL readability. It does not fully parse every database dialect or replace database-specific validation.

Will this tool change string values inside my SQL?

No. The formatter protects quoted strings and comments before applying whitespace and keyword formatting.

What SQL dialects does this work with?

It is designed for common SELECT, INSERT, UPDATE, DELETE, JOIN, GROUP BY, ORDER BY, and WHERE clauses across mainstream SQL dialects.
