The details that make debugging and cleaning up SQL faster, without ever leaving your browser.
Runs on your device
Parsing, formatting and minifying all happen locally in JavaScript. Your data never leaves your device.
Precise error detection
Invalid SQL gets pinpointed to the exact line and column, so you're not guessing where the syntax broke.
Advanced formatting

Questions people actually ask.
The short answers — with the long ones one tap away.
How do I format SQL with this tool?+
Paste your SQL into the box, or drop in a .sql file. Pick your indent size and any options, then tap Format SQL. The pretty-printed, color-coded result appears on the right, ready to copy or download.
Is my SQL uploaded to a server?+
No. Formatting, validating and minifying all happen locally in your browser using JavaScript. Your data never leaves your device, so it's safe to use with private or sensitive SQL.
Can this tool find errors in invalid SQL?+
Yes. If your SQL can't be parsed, the tool reports what went wrong along with the exact line and column where the problem starts, so you can jump straight to the fix.
Can I minify SQL instead of formatting it?+
Yes. Tap Minify to collapse your SQL into a single compact line with no extra whitespace — useful for shrinking query strings before embedding them in code.
Which SQL dialects are supported?+
The formatter supports standard SQL, MySQL, PostgreSQL, SQLite, and T-SQL (Microsoft SQL Server). It handles common DDL, DML, and DCL statements including SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and more.
Can I control the case of SQL keywords?+
Yes. You can choose to uppercase all keywords (e.g. SELECT, FROM), lowercase them (select, from), or preserve the original casing as written.
What indentation options are available?+
You can choose 2 spaces, 4 spaces, or a tab character for indentation. Minified output ignores this setting since it removes all whitespace.
Is this SQL formatter free to use?+
Yes, it's completely free with no account, no sign-up, and no limit on how many times you use it.
