What does the SQL formatter do?
Reformats minified or poorly indented SQL with consistent clause breaks, indentation, and keyword casing. Runs locally — queries are never uploaded.
Turn compressed queries into readable SQL for review, docs, and slow-query analysis.

A SQL formatter beautifies compressed or poorly indented SQL queries by adding consistent indentation, line breaks at clause boundaries, and keyword casing — making queries readable for review, documentation, and debugging.
SQL queries are often written or auto-generated in a single line or with inconsistent spacing, making them difficult to read and debug. A SQL formatter applies a set of style rules to produce clean, consistently indented SQL.
**What formatting does:**
• Breaks each SQL clause onto its own line (SELECT, FROM, WHERE, JOIN, GROUP BY, etc.)
• Indents nested subqueries
• Applies consistent keyword casing (UPPERCASE SQL keywords, lowercase identifiers — or custom)
• Aligns column lists and JOIN conditions
• Preserves string literals and comments
**Why it matters:**
• **Code review**: Readable SQL makes logic errors and missing conditions obvious
• **Documentation**: Formatted SQL in wikis and runbooks is maintainable
• **Debugging**: Aligned WHERE conditions and JOIN clauses make it easy to spot a wrong operator or missing join key
• **Collaboration**: Consistent style reduces noise in version control diffs
**Important**: Formatting is purely cosmetic — it never changes what a query does. The execution plan is identical for formatted and minified SQL.
Concise answers for common searches — definitions, steps, and comparisons.
Reformats minified or poorly indented SQL with consistent clause breaks, indentation, and keyword casing. Runs locally — queries are never uploaded.
Yes — formatting runs in your browser. Your SQL is never sent to any server.
Paste your raw, minified, or poorly formatted SQL into the input panel. Any valid SQL works — SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, stored procedures.
Choose your SQL dialect: Standard SQL, PostgreSQL, MySQL, or T-SQL (SQL Server). This affects how dialect-specific keywords and syntax are handled.
Select keyword casing (UPPERCASE/lowercase), indentation size (2 or 4 spaces), and whether to wrap long IN lists or CASE statements.
Click 'Copy' to copy the formatted query to your clipboard, ready to paste into your IDE, documentation, or code review tool.
Common real-world scenarios where this tool saves time.
ORMs (Django ORM, ActiveRecord, Hibernate) generate single-line queries logged to console. Paste the raw query, format it, and immediately see all JOIN conditions and WHERE filters clearly.
Include formatted SQL in wiki pages, runbooks, and README files. Formatted SQL is significantly more readable and maintainable in documentation.
Format before committing SQL migrations or query files. Consistent formatting reduces noise in pull request diffs — only logic changes are visible, not whitespace.
Paste slow queries from database logs (pg_stat_statements, MySQL slow query log) and format to understand structure before analyzing the execution plan.
Common SQL style standards.
| Style | Keywords | Identifiers | Used by |
|---|---|---|---|
| Traditional | UPPERCASE | lowercase | Most DBAs, Google style guide |
| All lowercase | lowercase | lowercase | Some developer teams |
| Mixed | UPPERCASE | snake_case | PostgreSQL community convention |
Consistency within a codebase is more important than which style you choose.

No. SQL formatting is purely cosmetic — whitespace, indentation, and keyword casing are ignored by the database engine. The query execution plan is identical for `SELECT id FROM users WHERE active=1` and the same query formatted across multiple lines.
The formatter handles Standard SQL and common constructs from PostgreSQL, MySQL, SQLite, and T-SQL (SQL Server). Complex dialect-specific features (PL/pgSQL procedural blocks, MySQL DELIMITER statements, T-SQL DECLARE/BEGIN/END blocks) may not indent perfectly — always review output.
Convention: SQL keywords UPPERCASE (SELECT, FROM, WHERE, JOIN), table and column names lowercase or quoted. This is the most widely used style (PostgreSQL, Google style, and most SQL linters default to it). Some teams prefer all-lowercase — consistency within a codebase matters more than which you choose.
Yes — there is no practical length limit. For extremely large queries (thousands of lines), formatting may take a moment, but all processing runs locally in your browser without uploading data.
No — both single-line comments (--) and block comments (/* */) are preserved in their original position. The formatter recognizes comment syntax and does not alter comment content.
Most SQL clients (pgAdmin, DBeaver, Azure Data Studio, DataGrip) have built-in formatters (usually Ctrl+Shift+F or Cmd+Shift+F). In VS Code, install the SQL Formatter extension. Use this web tool when you need quick formatting outside an IDE — for log snippets, wiki documentation, or sharing queries in chat.
Yes — the formatter includes a minify option that removes all unnecessary whitespace to produce a compact single-line query. Useful for embedding SQL in configuration files, environment variables, or connection strings.
Yes — all formatting runs in your browser using a JavaScript SQL parser. Your queries are never sent to EverydayTools servers. This makes it safe to format queries containing schema names, table structures, or sensitive filter conditions.
SQL queries you paste are formatted locally in your browser—they are not uploaded to EverydayTools servers.
Review formatted SQL before production use. Complex dialect-specific syntax may not format perfectly.
