Question 1

Is this SQL formatter free and private?

Accepted Answer

Yes. It is completely free, and all formatting happens locally in your browser — your SQL is never uploaded or stored on any server.

Question 2

Which SQL dialects are supported?

Accepted Answer

It targets standard SQL and works well with common dialects such as MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It is a best-effort beautifier, not a full SQL parser, so unusual or vendor-specific syntax may format imperfectly.

Question 3

Can I control keyword casing and indentation?

Accepted Answer

Yes. You can render keywords in UPPERCASE, lowercase, or keep them as typed, choose 2-space, 4-space, or tab indentation, and place commas at the end or the start of each line.

Question 4

Does it change my query's meaning?

Accepted Answer

No. The formatter only adjusts whitespace, line breaks, and keyword casing for readability. It does not rewrite, optimize, or execute your query.

Question 5

Will it format invalid SQL?

Accepted Answer

It applies best-effort formatting even to incomplete fragments, since it does not validate syntax. Always review the output, especially for complex queries with subqueries or vendor extensions.
