FAQ
What does the SQL Formatter do?
It formats and indents SQL queries for readability. Supports SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and more.
What SQL dialects are supported?
Standard SQL, PostgreSQL, MySQL, SQLite, MS SQL Server, and Oracle syntax.
Does it validate SQL syntax?
It formats the structure but does not validate against a database. Syntax errors may still be present in the formatted output.
Can it minify SQL?
Yes. Toggle between formatted (readable) and minified (compact) output.
Is my SQL uploaded?
No. All formatting happens in your browser using JavaScript.
Does it handle subqueries?
Yes. Nested subqueries are properly indented at each level.
Can I change the indentation?
Default is 2 spaces. Also supports 4 spaces and tabs.
Does it uppercase keywords?
Yes. SQL keywords (SELECT, FROM, WHERE, etc.) are uppercased. Identifiers keep their original case.
What is the character limit?
No practical limit. The formatter handles queries of any length.
Does it work on mobile?
Yes. Paste or type SQL on any device.
Can I upload a .sql file?
Yes. Click Upload to load a .sql file.
Is there a download option?
Yes. Download the formatted SQL as a .sql file.
