Quick answer

To format SQL, paste your query into the box and it beautifies live, putting each clause (SELECT, FROM, WHERE, JOIN) on its own line with clean indentation. YaliKit's SQL formatter lets you force keywords to UPPERCASE, pick 2, 4, or 8-space indent, and choose from 12 dialects like MySQL and PostgreSQL, plus a minify mode. It runs entirely in your browser, so your query stays private, and it never rewrites text inside string literals or comments.

Why Use SQL Formatter & Beautifier?

Beautify Live As You Type

Paste a messy query and it reformats instantly with clause-per-line layout, aligned conditions, and clean indentation. No button to hunt for.

12 SQL Dialects

Choose Standard SQL, MySQL, PostgreSQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle (PL/SQL), BigQuery, Snowflake, Redshift, Spark, or Db2.

Keyword Casing & Indent

Force keywords to UPPERCASE (the common style guide default), lowercase, or keep them as-is. Pick 2, 4, or 8-space indentation.

Never Corrupts Your Query

Built on the sql-formatter engine, so string literals, quoted identifiers, and comments are preserved exactly. Only whitespace changes.

Minify To One Line

Switch to Minify to collapse a query onto a single compact line, safely, without touching text inside strings or comments.

100% Client-Side

Every query is formatted in your browser with JavaScript. Nothing is uploaded, so it works offline and keeps your SQL private.

Common Uses for the SQL Formatter

Code Reviews

Format SQL before opening a pull request so reviewers can read the query at a glance instead of parsing one giant line.

Query Debugging

Beautify a tangled query to spot a missing join condition, a stray AND/OR, or a mis-scoped WHERE clause quickly.

Clean Version Control Diffs

Standardize formatting before committing so diffs show real logic changes, not whitespace noise.

Docs & Tutorials

Format SQL examples for documentation, blog posts, and knowledge base articles so they read cleanly.

How It Works

1

Paste Your SQL Query

Drop in SQL from your editor, database client, ORM log, or anywhere. Or click Load sample to try it instantly.

2

Pick Dialect, Casing & Indent

Choose your database dialect, set keywords to UPPERCASE, lowercase, or keep, and select 2, 4, or 8-space indent. It reformats live as you change options.

3

Copy or Download the Result

Copy the formatted SQL to your clipboard with one click, or download it as a .sql file. Switch to Minify for a compact one-line version.

Tips for Formatting SQL

Use UPPERCASE for Keywords

Most SQL style guides uppercase keywords (SELECT, FROM, WHERE) so they stand out from table and column names. It is the default here.

Format Before You Commit

Run SQL through the formatter before committing so diffs stay clean and reviews focus on logic, not whitespace.

Pick the Right Dialect

Selecting your actual database (MySQL, PostgreSQL, T-SQL, and so on) formats dialect-specific syntax like backtick identifiers or casts correctly.

Frequently Asked Questions

Paste your SQL into the input box and it beautifies live as you type, adding a line break for each clause (SELECT, FROM, WHERE, JOIN) and consistent indentation. Pick your dialect, set keyword casing to UPPERCASE, and choose 2, 4, or 8-space indent. Then click Copy or Download. It all runs in your browser.
Beautifying SQL adds consistent line breaks, indentation, and spacing so a long query is easy to read, without changing what it does. Only whitespace and keyword casing change, so the query returns the exact same results. The reverse is minifying, which collapses the query to one compact line.
Twelve dialects: Standard SQL, MySQL, PostgreSQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle (PL/SQL), BigQuery, Snowflake, Redshift, Spark SQL, and Db2. Picking the right dialect means dialect-specific syntax like backtick identifiers or double-colon casts is formatted correctly.
No. Formatting only changes whitespace, line breaks, and (optionally) keyword casing. The tables, columns, conditions, and logic are untouched, so the query executes identically. String literals, quoted identifiers, and comments are preserved exactly as you wrote them.
Most SQL style guides recommend UPPERCASE for keywords (SELECT, FROM, WHERE, JOIN) so they stand out from table and column names, which is the default here. Some teams prefer lowercase for readability. Use the Keywords option to force UPPERCASE, lowercase, or keep your original casing.
Yes. Nested subqueries are indented at each level, every JOIN and ON clause gets its own line, and WITH (common table expression) blocks are laid out clearly. Complex queries with multiple joins and conditions become far easier to read and debug.
Click the Minify tab. It collapses your query onto a single line by removing extra whitespace and line breaks, which is handy for logs or config values. Text inside string literals and comments is protected, and a mid-query line comment is rewritten to a block comment so the one-liner stays valid.
Yes to both. All formatting happens in your browser with client-side JavaScript, so your queries never touch a server or any third party, and it works offline. The tool is completely free with no signup, no limits, and no watermark.
