Formatting uses a client-side SQL formatter. Minification removes comments and collapses whitespace locally.

Formatting options

Best for quick readability improvements, query cleanup and SQL snippets copied from logs or apps.

Input characters

Output characters

0

Statements

Compression

0%

Paste SQL to reformat multi-line queries or compress them for transport.

Workflow notes

Use formatting to inspect logic. Use minification when you need a compact query string with comments removed.

Readable clauses

Break long `SELECT`, `JOIN`, `WHERE` and `ORDER BY` logic into cleaner lines.

Quick cleanup

Normalize keyword case and indentation before saving snippets to docs or code reviews.

Compact output

Remove comments and whitespace when you need a tighter one-line SQL statement.

What this tool does

SQL Formatter and Minifier gives you two common query-cleanup workflows on one page. Formatting makes long statements easier to review, while minification removes comments and collapses whitespace for compact transport or embedding in configuration.

This is useful when SQL snippets come from logs, dashboards, tickets or application settings and need to be cleaned up quickly without opening an editor or database tool.

  • Beautify SQL into a more readable multi-line structure.
  • Normalize keyword case for cleaner docs and reviews.
  • Minify SQL by removing comments and compressing extra whitespace.

When to use it

Use formatting when you need to inspect joins, predicates and clause order during debugging or review. Better spacing often reveals duplicated logic, suspicious filters and formatting mistakes that are hard to notice in one-line SQL.

Use minification when you need a tighter statement for config files, generated code or debugging environments where comments and line breaks add noise.

  • Clean pasted queries before code review or documentation.
  • Turn compressed SQL from logs into something easier to inspect.
  • Strip comments and whitespace before embedding SQL elsewhere.

Best practices and limitations

Formatting improves readability, but it does not validate database semantics. A query can look cleaner and still be logically wrong, inefficient or incompatible with your target database.

Minification removes comments and extra whitespace, which is useful for compact output but not ideal if you still need explanation text inside the query. Keep a readable version when comments matter.

  • Review formatted SQL before assuming the logic is correct.
  • Keep a readable copy if comments or explanation lines matter.
  • Use the tool for cleanup, not as a replacement for query execution or optimization analysis.

How to use

  • Paste SQL text or import a local `.sql` file.
  • Choose indentation and keyword case, then click Format SQL for readability or Minify SQL for compact output.
  • Copy or download the transformed SQL for docs, debugging or application configuration.

Example

Input

select id,email from users where status='active' order by created_at desc;

Output

SELECT
    id,
    email
FROM users
WHERE status = 'active'
ORDER BY created_at DESC;

Privacy note

SQL formatting and minification happen locally in the browser. If you import a `.sql` file, the contents stay on your device and are not uploaded.

FAQ

Does the SQL formatter run in the browser?

Yes. Query formatting and minification happen locally in your browser.

What does minify remove?

Minification strips SQL comments and collapses unnecessary whitespace to produce a tighter query string.

Can I choose uppercase or lowercase keywords?

Yes. The formatter includes a keyword case option so you can standardize the output for your preferred style.

Does formatting validate SQL for a specific database engine?

No. The formatter improves readability, but it does not guarantee that the query is valid for every SQL dialect or environment.

Should I format before sharing SQL in docs or tickets?

Yes. Clean formatting makes SQL easier for reviewers and teammates to understand quickly.
