SQL Query Formatter

This page provides the SQL Query Formatter tool. Utilize it for your tasks.

Why Use an Online SQL Query Formatter?

An SQL Query Formatter—sometimes called a SQL beautifier or pretty-printer—automatically restructures messy statements into clean, readable code. Formatting your SQL before you push to Git or hand off to teammates offers several SEO-friendly benefits:

  • Improved readability: consistent indentation, keyword case, and line breaks make even 300-line reports easy to scan.

  • Faster debugging: aligned JOIN clauses and nested subqueries highlight logic errors at a glance.

  • Team standards compliance: enforce style guides across MySQL, PostgreSQL, SQL Server, Oracle, BigQuery, and more.

  • Cleaner diffs in pull requests: whitespace noise disappears, leaving only true logic changes.

How the SQL Query Formatter Works

  1. Choose Your Dialect
    Select Standard SQL, T-SQL, PL/pgSQL, Snowflake, Redshift, etc. The formatter applies dialect-specific rules for functions, quotes, and system keywords.

  2. Set Preferences

    • Tab size (2 or 4 spaces)

    • Uppercase or lowercase keywords

    • Align SELECT columns and JOIN conditions

    • Collapse or expand subqueries

  3. Paste Your Query & Click “Format Code”
    In milliseconds, your SQL is re-indented, keywords are cased correctly, trailing commas are fixed, and redundant whitespace is removed.

  4. Copy or Download
    Grab the formatted output for documentation, dashboards, or commit history.

Pro Tips for Consistently Beautiful SQL

  • Break up long SELECT lists by aligning each column on its own line, ending with a comma.

  • Keep JOIN logic visible by placing the join condition on a new indented line.

  • Nest subqueries with an extra two spaces to distinguish levels clearly.

  • Use CTEs (WITH clauses) instead of deeply nested subqueries—the formatter keeps each CTE block tidy.

Frequently Asked Questions

Does formatting change query performance?
No. The formatter adjusts whitespace and casing only; execution plans stay identical.

Can I auto-uppercase functions like COUNT()?
Yes—toggle “Uppercase Functions” in advanced settings.

Will it work with stored procedures and triggers?
Absolutely. Paste any DDL/DML block and receive fully formatted code.

Is my SQL stored or logged?
Never. All formatting runs in-memory over an encrypted connection and is discarded once you close the page.
