SQL Formatter is a free online tool to beautify and format SQL queries. It runs entirely in your browser, so your files never leave your device — nothing is uploaded. There's no sign-up, no watermark, and it works on any modern browser on desktop or mobile.
How to use SQL Formatter
This free SQL formatter beautifies messy queries into clean, readable SQL with proper indentation and consistent keyword casing. It supports standard SQL and popular dialects, making it easy to tidy queries copied from logs, ORMs or code. Formatting happens entirely in your browser, so your queries are never uploaded or stored.

Readable output
Consistent indentation and line breaks make long queries far easier to scan and review.
Dialect aware
Handles standard SQL plus popular dialects so your specific syntax is formatted correctly.
Private formatting
Queries are processed in the browser, so confidential schema and table names never leave your machine.
Format an ORM-generated query from logs
When Hibernate, Sequelize, or Django logs a single-line query with cryptic aliases and no line breaks, it is hard to debug. Paste that raw statement here and choose your dialect (MySQL, PostgreSQL, SQL Server, SQLite, or BigQuery). The formatter reflows joins, WHERE clauses, and subqueries onto indented lines so you can finally read what your ORM actually sent to the database.
Beautify minified SQL without leaking schema
Production queries expose real table names, column names, and sometimes literal values, so pasting them into a random web service is a quiet data leak. This tool runs entirely in your browser using the sql-formatter engine, so nothing is uploaded. Drop in a compressed one-line query, hit Format, and get clean two-space indentation back while your confidential schema never touches the network.
Standardize keyword casing for a pull request
Reviewers hate inconsistent SQL where SELECT, select, and Where all appear in one query. Use Format to uppercase every keyword for a uniform house style, or click Keep casing to preserve your existing capitalization while only fixing the indentation and line breaks. Either way the logic and result set stay identical, giving you tidy, review-ready SQL to commit alongside your code.
SQL Formatter — frequently asked questions
Does formatting change what my query does?
No. The formatter only adjusts whitespace, line breaks and keyword casing. The logic and results of your query stay exactly the same.
Which SQL dialects are supported?
It handles standard SQL along with common dialects, so queries written for popular databases are reformatted cleanly. Dialect-specific keywords are preserved.
Is my query data safe?
Yes. Everything runs client-side in your browser. Your SQL, including any table or column names, is never sent to or stored on a server.
