Which library powers this SQL formatter?

This tool uses a custom JavaScript regular expression tokenizer and keyword replacer built directly into the application source code. It does not import external libraries like sql-formatter.

Which SQL syntax does this tool support?

The formatter formats standard ANSI SQL keywords (such as SELECT, FROM, WHERE, JOIN, ORDER BY) and applies consistent indentation and clause line breaks. It does not parse or validate vendor-specific syntax or proprietary extensions.

Does this tool validate or execute SQL queries?

No. The tool is strictly a text formatting and minification utility. It does not validate SQL syntax against a grammar engine, check database schemas, or execute commands against a database server.

Are my database queries or schema names uploaded to remote servers?

No. All text parsing, keyword replacement, and formatting logic execute entirely inside your local browser memory.

SQL Query Formatter & Beautifier

Format, beautify, and minify SQL database statements directly in your browser. This tool uses a custom JavaScript regular expression tokenizer and keyword normalization engine implemented directly in the application source code rather than external npm packages. It standardizes common SQL keywords to uppercase, breaks main clauses onto distinct lines, indents sub-clauses and selected column lists with customizable two-space or four-space indentation, and collapses redundant whitespace. In minification mode, it strips block comments, inline comments, and extraneous spacing to produce compact single-line query strings. The tool formats and minifies query strings only: it does not validate syntactic correctness against specific database grammar rules, does not isolate SQL keywords inside quoted string literals or comments from uppercasing, and does not execute queries against a database. All processing runs client-side with zero network transmission.

How to use

Step 1: Paste SQL Statement

Input your raw, minified, or unformatted SQL query into the input editor pane or load the sample query.
Step 2: Configure Formatting Preferences

Toggle uppercase keyword normalization, set indentation to two or four spaces, or enable minification mode.
Step 3: Copy Beautified SQL

Click to copy the clean, formatted SQL query directly to your clipboard for database management tools.

Options explained

Keyword Uppercasing

Capitalizes standard ANSI SQL keywords (such as SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY). Note that keywords inside string literals or comments are also matched.

When to use: Use to ensure consistent styling conventions across simple engineering queries and scripts.

Indentation Spacing (2 Spaces vs 4 Spaces)

Controls whitespace tab width applied to projected columns and nested clause statements.

When to use: Use two spaces for compact code in web applications or four spaces for terminal console readability.

Minification Mode

Removes multi-line comments, single-line dashes, and collapses whitespace around punctuation.

When to use: Use when embedding compact SQL query strings inside application code or configuration files.

Worked example

Input: select id, name from users where status = 'active' order by id desc;

Output: SELECT id, name FROM users WHERE status = 'active' ORDER BY id DESC;

Example formatting; output arrangement reflects selected indentation and uppercase settings.

Tips & limits

Formatting runs client-side in browser RAM; database schemas and queries are never sent to external servers.
The minification mode strips comments; preserve documentation in source control before minifying queries.
This tool focuses on formatting structure and does not verify whether tables or column names exist.

Common problems

Query formatting looks unchanged: Ensure the input query contains recognizable ANSI SQL keywords matching standard capitalization patterns.
Comments disappear when minified: Minification mode intentionally removes comment blocks and single-line remarks to produce minimal payloads.
