What is SQL Beautifier?

SQL Beautifier is a free, browser-based tool that helps you make messy data readable. Reformat SQL queries with proper line breaks. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.

3Copy the formatted output or download it for use in your project.

Examples

Example 1

Example input

select id,name from customers where plan='pro' order by name

Example output

SELECT
  id,
  name
FROM customers
WHERE plan = 'pro'
ORDER BY name

Example 2

Minified input

One-line content with no helpful spacing

Readable output

Indented output where nested structure is visible.

Example 3

Over-spaced input

Content with inconsistent line breaks and indentation

Normalized output

Consistent formatting that is easier to review and diff.

Example 4

Deeply nested input

A record with nested arrays, objects, clauses, or sections

Structured output

Nested levels are separated so each block is easier to inspect.

Example 5

Compact output request

Formatted content that needs to be pasted into a small field

Minified output

Whitespace is removed while the underlying value remains the same.

Common errors

Formatting is used before validating, so syntax errors remain hidden.
Minified output is pasted where humans still need to review it.
Tabs and spaces are mixed in a way that makes diffs noisy.
A formatter is expected to fix semantic data problems that require cleaning instead.

How it works

1Parses or tokenizes the SQL input.
2Applies consistent spacing, indentation, or compacting rules.
3Returns output without changing the meaning of the data.
