What is a SQL Formatter?

During database development and operations, we often encounter complex SQL query statements. These statements can become difficult to read due to missing indentation, inconsistent casing, or lack of comments. SQL Formatter automatically converts messy SQL code into a clear, standardized format. It helps developers quickly locate logical errors and improves code readability during team collaboration.

Frequently Asked Questions (FAQ)

Is this tool safe?

Absolutely safe. This tool runs entirely in your browser locally (pure client-side processing). Your data will not be uploaded to any server.

Which database SQL syntax does it support?

It currently supports standard SQL and common variants. If you have specific database syntax needs (like MySQL, PostgreSQL, Oracle), the tool aims to maintain general compatibility.

Why does the formatted code look different now?

The purpose of the formatter is to standardize code style. It adjusts spaces, line breaks, and casing (usually keywords become uppercase or lowercase depending on configuration), but it does not alter the logical meaning of the SQL.
