More about this tool

Frequently Asked Questions

What does the SQL formatter do?

It adds line breaks and indentation to SQL so queries are easier to read, check, and discuss.

Does the service validate SQL syntax?

No. The formatter is not a strict SQL validator and does not check dialect-specific syntax. It only formats query text.

Does the tool execute SQL queries?

No. The tool does not connect to a database or execute SQL. It works with text in the browser.

Which SQL dialects are supported?

You can choose Generic SQL, PostgreSQL, MySQL, SQLite, or MSSQL for formatting hints. This is not full dialect validation.

Can keywords be uppercased?

Yes. Settings can use UPPERCASE, lowercase, or leave keyword case unchanged.

Are SQL comments preserved?

Yes, if comment preservation is enabled. Line comments -- and block comments /* */ are supported.

What happens to quoted strings?

String literals should stay unchanged so formatting does not break values, SQL patterns, or text inside the query.

Does the service warn about dangerous commands?

The tool may warn if it sees DROP, DELETE, TRUNCATE, ALTER, or UPDATE/DELETE without WHERE. This is not full security analysis.

Is my data sent to the server?

No. Processing runs locally in your browser and data is not sent to the server.

Do I need to register?

No. The tool works without registration.
