Does this tool support my specific database?

Yes, we support many popular dialects including MySQL, PostgreSQL, SQL Server (T-SQL), Snowflake, BigQuery, and SQLite.

Can I change the indentation style?

Yes, you can customize the indentation size and tab width to match your project's specific style guide.

Is my data stored on your servers?

No, this tool processes your queries locally in your browser to ensure your database code remains private.

Will formatting change the logic of my query?

No, the formatter only adjusts whitespace, line breaks, and keyword casing; the functional logic of your SQL remains identical.

Can I force keywords to be uppercase?

Yes, you can toggle the 'Uppercase Keywords' option to ensure all SQL commands like SELECT, FROM, and WHERE are standardized.

Examples

1. Standardizing Legacy Queries

Database Administrator

Background

A legacy database migration project involved hundreds of lines of unformatted, single-line SQL queries.

Problem

The lack of indentation made it impossible to identify join conditions and filter logic quickly.

How to use

Paste the minified SQL into the tool, select 'PostgreSQL' as the dialect, and apply a 4-space indent.

indentSize: 4, uppercase: true, language: 'postgresql'

Outcome

The query was instantly transformed into a readable, multi-line format, allowing the team to identify and fix a missing join condition in minutes.

2. Preparing Code for Documentation

Software Developer

Background

A developer needed to include a complex analytical query in the project's internal API documentation.

Problem

The raw query was messy and did not meet the company's internal code style requirements.

How to use

Input the query, enable 'Uppercase Keywords', and set the tab width to 2.

indentSize: 2, uppercase: true, language: 'mysql'
