Online SQL Formatter & Beautifier

What is a SQL Formatter & Beautifier?

I built this tool to take raw or compressed SQL queries and transform them into clear, well-indented statements. It splits major clauses onto their own lines, aligns joins and conditions, and indents subclauses so you can read and debug your SQL with ease.

What Does Our SQL Formatter & Beautifier Do?

When you click Prettify SQL the script normalizes whitespace, then inserts line breaks before key clauses like SELECT, FROM, WHERE, JOIN, GROUP BY, and ORDER BY. It trims each line and indents lines that follow a clause header to highlight nested conditions and join expressions.

What to Expect When Using This Tool

You will see two text areas labeled SQL Input and Formatted Output. On desktop they sit side by side, on mobile they stack vertically. Paste your SQL into the left box, click Prettify SQL, and inspect the organized result on the right. Clear All resets both fields so you can start over.

Common Use Cases

• Cleaning up ad-hoc queries for review
• Preparing SQL examples for documentation or blog posts
• Auditing long queries to identify join or filter logic
• Standardizing query style across a team
• Debugging nested subqueries or complex conditions

Input and Output Examples

Example 1

Input:

SELECT id,name,age FROM users WHERE active=1 ORDER BY name;

Output:

SELECT
  id,
  name,
  age
FROM
  users
WHERE
  active = 1
ORDER BY
  name;

Example 2

Input:

SELECT u.id,u.name,o.total FROM users u INNER JOIN orders o ON u.id=o.user_id WHERE o.total>100 GROUP BY u.id ORDER BY o.total DESC;

Output:

SELECT
  u.id,
  u.name,
  o.total
FROM
  users u
  INNER JOIN orders o ON u.id = o.user_id
WHERE
  o.total > 100
GROUP BY
  u.id
ORDER BY
  o.total DESC;

Frequently Asked Questions

What if my SQL uses uncommon clauses?

The tool targets common clauses. Unrecognized clauses remain on the same line but follow general whitespace trimming.

Will it uppercase my keywords?

It converts recognized keywords to uppercase. Other parts of your query remain unchanged.

Can it handle multiple statements?

It processes the entire input as one block. Separate statements with semicolons and run them one at a time.

Does it validate SQL syntax?

No. It formats based on patterns. You should validate or execute your SQL separately.

Can I use it on mobile?

Yes. The responsive design stacks panels for easy use on small screens.

Does my data leave my browser?

No. Formatting happens locally in JavaScript so your queries stay private.

How do I copy the formatted SQL?

Select the Formatted Output area and use your device’s copy command.

Can I adjust indentation?

Not in this version. It uses two spaces per indent level.

Will it reformat string literals?

It preserves everything inside quotes. Only whitespace outside strings is normalized.
