Continue your workflow

SQL Formatter applies text-based formatting to common SELECT, FROM, WHERE, JOIN, GROUP BY, and ORDER BY patterns for easier review and documentation.

Minify mode collapses whitespace when you need a compact single-line query for logs or embedded scripts.

Runs locally — avoid pasting production credentials even when processing stays on your device.

Common uses for SQL Formatter

Typical tasks this tool is built for.

Format long SQL queries for debugging and review.
Make joins, filters, and conditions easier to read.
Minify SQL into a compact single-line output.
Standardize SQL style for internal documentation or team sharing.

How to use SQL Formatter

Step 1. Paste your SQL into the input area.
Step 2. Select the keyword list that most closely matches the SQL dialect you are reviewing.
Step 3. Set 2 spaces, 4 spaces, or tabs, then choose keyword and identifier case options as needed.
Step 4. Decide whether to remove comments, compact formatted output, or append a semicolon before processing.
Step 5. Use Format SQL for the component’s line breaks and indentation, or Minify SQL for whitespace-compacted output.
Step 6. Review quoted content, comments, procedural statements, and vendor-specific syntax before copying or downloading the result.

Why use this tool?

Pretty-print common SQL patterns with custom text transformations and selected dialect keyword lists; it is not a complete SQL parser.
Choose Standard SQL, MySQL, PostgreSQL, SQLite, SQL Server, or Oracle keyword lists before formatting.
Use 2 spaces, 4 spaces, or tabs for formatted indentation.
Set keyword and identifier casing independently as uppercase, lowercase, or preserved where those options apply.
Copy the current output or download it as a .sql file after Format SQL or Minify SQL produces a result.

Privacy and formats

SQL formatting and minify run locally in your browser. Queries are not sent to a server.

Best results with SQL Formatter

Practical tips before you download or share the output.

This formatter improves readability for common SQL patterns, but it is not a full SQL parser. Very advanced procedural SQL may need custom handling.

Common problems this tool helps with

Situations where this workflow saves time.

Nothing happens - enter SQL containing non-whitespace text before choosing Format SQL or Minify SQL.

You expect syntax validation - the component applies custom text transformations and does not fully parse or execute SQL.

A dialect-specific construct looks wrong - the selected dialect changes keyword lists, not the parser coverage for every vendor extension.

A stored procedure or nested block needs review - procedural SQL can be formatted imperfectly by text-based rules.

Quoted strings or identifiers changed unexpectedly - inspect output carefully because the formatter protects quoted spans only within its implemented transformations.

A comment disappeared - Remove comments deletes -- line comments and /* ... */ comments when selected.

Compact output makes a line comment hard to interpret - whitespace compaction can change how surrounding text is presented, so review line comments before execution.

Adding a semicolon changes the ending - that option appends one only when the trimmed output does not already end with a semicolon.

Frequently asked questions

Which SQL dialect options are available?

The selector offers Standard SQL, MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It uses the chosen dialect’s keyword list during its text transformations.

What indentation choices are available?

Format SQL can use 2 spaces, 4 spaces, or tabs. Minify SQL instead collapses whitespace to create compact output.

Can I control keyword and identifier case?

Yes. The component has separate keyword-case and identifier-case selectors with uppercase, lowercase, and preserve choices.

What does Compact output do?

In Format SQL, Compact output collapses whitespace instead of applying the normal formatted line-break path. Minify SQL also collapses whitespace, using the selected casing and comment settings.

What does Remove comments remove?

When selected, it removes -- line comments and /* ... */ comment blocks before the output is built. Leave it off when those comments are needed for review or execution context.

What does Add semicolon change?

It appends a semicolon to trimmed output only if there is not already one at the end. It does not validate whether that terminator is appropriate for the SQL you entered.

Does the formatter validate or run SQL?

No. It does not execute SQL or provide complete syntax validation. Treat the result as text that still needs review and testing in its intended database environment.

Will formatting preserve query meaning?

No such guarantee is implemented. Comments, procedural SQL, quoted content, and vendor-specific syntax deserve manual review before the output is executed.

Can I copy or download the result?

Yes. Copy output uses the browser clipboard API, and Download creates a formatted.sql file with an application/sql content type when output is available.
