SQL Formatter
SQL Formatter beautifies queries with uppercase keywords, one clause per line and indented columns — or minifies them to a single line. String literals and comments are preserved exactly as written.
Last updated: July 2026
A SQL formatter rewrites messy queries into readable form: keywords are uppercased, each clause (SELECT, FROM, WHERE, JOIN) starts on its own line, and select-list columns are indented one per line. It can also minify a query to a single line. Everything runs in your browser; your SQL is never uploaded.
🔒 Formatting happens in your browser — your SQL is never uploaded.
How to use SQL Formatter
- Paste your SQL query or script.
- Click “Format” to beautify or “Minify” to compact.
- Copy the formatted result with one click.
Frequently asked questions
Which SQL dialects does it support?
It formats standard SQL (SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, JOINs) and works fine with MySQL, PostgreSQL, SQLite and SQL Server queries.
Will it change my string literals or comments?
No. Quoted strings, quoted identifiers and comments are tokenized first and passed through untouched — only whitespace and keyword casing change.
Is my SQL uploaded?
No — formatting happens entirely in your browser. Queries never leave your device.
