In short
SQL Formatter is a free online tool on inputtesthub.com that formats SQL queries with proper keyword casing, indentation and line breaks for MySQL, PostgreSQL, SQL Server and SQLite. It needs no account, no download and no payment, and there is no daily usage limit. Everything is processed inside your own browser, so the data you paste is never uploaded to a server.
How to use the SQL Formatter
- Paste your code into the input area.
- Choose the indentation and output options you want.
- Read the formatted result, then copy or download it.
About the SQL Formatter
The SQL Formatter formats SQL queries with proper keyword casing, indentation and line breaks for MySQL, PostgreSQL, SQL Server and SQLite. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Making a 300-character one-line query readable.
- Standardising queries before a code review.
- Reading a query pulled from application logs.
Frequently asked questions
Does the SQL Formatter cost anything?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Can you see what I put into this tool?
No. The SQL Formatter runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What do people use the SQL Formatter for most?
In practice it gets used for three things: making a 300-character one-line query readable. Standardising queries before a code review. Reading a query pulled from application logs. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the tool works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
