SQL Formatter

Format and beautify SQL queries online free

What is the SQL Formatter?

The sql formatter works like this: it pretty-prints SQL queries with keyword casing, clause indentation and JOIN alignment for MySQL, Postgres and generic dialects. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

How to use the SQL Formatter

1. Paste the input (code, data or query).
2. Run the operation - formatting and validation are instant.
3. Read any validation message before trusting the output.
4. Copy the result into your project.

Features

• Instant client-side formatting and validation
• No telemetry on your data
• Copy-ready output with proper escaping

Common mistakes to avoid

• Using the wrong input dialect (JSON vs JSON5, cron 5 vs 6 fields)
• Copying output without checking escaping

Examples

Input	Result
SELECT a,b FROM t WHERE x=1	SELECT a, b FROM t WHERE x = 1

Best used for

• Getting a reliable answer for sql formatter without installing an app
• One-off tasks done in under a minute from any device
• Checking results before committing them to something important
• Working on a phone where desktop software is unavailable

Privacy

All parsing and transformation happens locally in this tab - your code and data are not sent anywhere.

Frequently asked questions

Does it understand my database's dialect?

It formats standard SQL well; vendor-specific syntax (PL/SQL blocks, MSSQL hints) is preserved but not specially indented.

Which SQL dialect is assumed?

Generic ANSI SQL with sensible keyword casing, plus MySQL and Postgres modes for their specific literal and function quirks - the formatting never rewrites your logic.

Does formatting touch the query's semantics?

No - only whitespace, casing and clause indentation change. Identifiers, values and functions come out byte-identical to what you pasted.
