Frequently Asked Questions

Standard SQL, MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, Snowflake, Spark SQL, SQL Server (T-SQL), and Oracle PL/SQL. Selecting the right dialect ensures dialect-specific keywords and syntax are handled correctly.
No. Formatting only reflows whitespace, line breaks, indentation, and keyword casing. The query itself — tables, columns, conditions, and order — is unchanged. It does not connect to any database or execute anything.
No. The query is formatted entirely in your browser with the open-source sql-formatter engine. Nothing is uploaded, so it is safe for production queries that reveal schema names or business logic.
Consistently formatted SQL is far easier to read, review, and debug. Putting each clause on its own line with proper indentation makes joins, filters, and grouping obvious, and standardized casing keeps a team codebase tidy.
Yes. The formatter re-indents the text it is given without validating that the query is runnable, so you can tidy work-in-progress snippets and fragments.

Format Messy SQL in One Click

Paste a one-line query or a wall of un-indented SQL and get clean, consistently-formatted output with each major clause (SELECT, FROM, JOIN, WHERE, GROUP BY) on its own line, proper indentation, and standardized keyword casing. It makes queries easier to read in code review, easier to debug, and consistent across your team.

Ten SQL Dialects Supported

Different databases have different keywords and syntax quirks. This formatter understands Standard SQL, MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, Snowflake, Spark SQL, SQL Server (T-SQL), and Oracle PL/SQL. Pick your dialect so identifiers and functions are handled correctly.

Your Query Never Leaves Your Browser

Production SQL often embeds table names, schema details, and sometimes literal values that reveal business logic. This tool formats everything locally with the open-source sql-formatter engine loaded into your browser — nothing is sent to a server, so it is safe for proprietary and sensitive queries that you should never paste into an online chatbot.

Formatting Is Not Validation

This tool re-indents and standardizes the text of your query; it does not connect to a database or check that the query runs. It will happily format syntactically incomplete SQL so you can tidy work-in-progress snippets.
