SQL formatter
Paste messy or minified SQL and get clean, consistently indented output in one click. Runs entirely in your browser — nothing is sent to a server.
What is SQL formatting?
SQL formatting — sometimes called SQL beautifying or SQL pretty-printing — transforms compressed or inconsistently styled queries into clean, readable code. It applies consistent indentation, line breaks, and keyword casing so the logical structure of a query is immediately visible.
This matters more than it sounds. Poorly formatted SQL hides bugs, makes code reviews slower, and creates friction every time a teammate opens a query they didn't write. A formatter removes that friction in seconds.
When to use a SQL formatter
- Cleaning up auto-generated or ORM-produced queries before committing them
- Standardizing query style across a team, codebase, or wiki
- Making complex joins, subqueries, and CTEs easier to scan
- Preparing SQL snippets for documentation, pull requests, or Slack messages
- Reformatting one-liner queries from application logs into something readable
How the formatter handles different dialects
Each SQL dialect has its own reserved words, quoting conventions, and syntax quirks. This tool parses your query using dialect-specific grammar rules — so PostgreSQL-specific syntax like ILIKE or BigQuery's backtick-quoted identifiers are handled correctly instead of being treated as generic tokens.
From formatted SQL to instant charts
If you're writing and formatting SQL for analytics and reporting, Basedash can skip that entire step. Describe the chart or metric you want in plain English, and Basedash writes the SQL, runs it against your actual data, and renders the visualization — all in seconds. It connects to PostgreSQL, MySQL, BigQuery, Snowflake, and 750+ other data sources.
FAQ
What SQL dialects are supported?
This tool supports Standard SQL, PostgreSQL, MySQL, MariaDB, BigQuery, SQLite, SQL Server (Transact-SQL), Amazon Redshift, Spark SQL, and PL/SQL. Each dialect uses its own grammar rules so reserved words and quoting conventions are handled correctly.
Is my SQL stored or sent to a server?
No. All formatting happens entirely in your browser using JavaScript. Your SQL is never transmitted, logged, or stored anywhere.
Does formatting change what my query does?
No. The formatter only changes whitespace, indentation, and optionally keyword casing. The logical meaning and execution behavior of your query stays exactly the same.
Can I format multiple statements at once?
Yes. If you paste multiple SQL statements separated by semicolons, the formatter will handle each one and separate them with blank lines in the output.
How does this compare to IDE or VS Code formatters?
This tool uses the same sql-formatter library that powers many popular IDE extensions. The advantage is that it works instantly in any browser — no install, no configuration, and easy to share with teammates who may use different editors.
What does the keyword casing option do?
The keywords setting controls whether SQL reserved words like SELECT, FROM, and WHERE are uppercased, lowercased, or left as-is. Uppercase is the most common convention and is selected by default.
