How do I format and beautify SQL?

Paste a query into AnyTool's SQL Formatter and it reindents and beautifies it for your chosen dialect — Postgres, MySQL, T-SQL, BigQuery, Snowflake, and more. A real tokenizer runs in your browser, so your SQL is never uploaded.

  • 17 dialects with proper tokenizer-based formatting
  • Keyword/identifier case control and indentation options
  • Minify mode and comment-safe formatting
  • 100% in your browser — no upload, no signup, free

What is

SQL Formatting

SQL formatting reindents and beautifies a query — adding line breaks before clauses, aligning conditions, and standardizing keyword case — so it is readable and consistent. A dialect-aware formatter respects each database's syntax.

Frequently Asked Questions

No — formatting runs entirely in your browser, so your query is never uploaded.

AnyTool formats SQL locally with a bundled tokenizer-based engine (no runtime CDN), so your query never reaches a server — unlike server-side tools like Redgate, DPriver, or FreeFormatter.

It supports 17 dialects including Postgres, MySQL, SQL Server, Oracle, BigQuery, and Snowflake.

The formatter understands the full sql-formatter dialect set — Postgres, MySQL, MariaDB, SQL Server (T-SQL), PL/SQL, BigQuery, Snowflake, Redshift, SQLite, DuckDB, Spark, ClickHouse, Trino, DB2, N1QL, and standard SQL — so output matches your database.

Yes — a real tokenizer preserves comments and handles nested subqueries and CTEs.

Because it tokenizes the query rather than using fragile regex, it preserves -- and /* */ comments and correctly formats subqueries, CTEs, CASE expressions, and window functions.

Detailed Explanation

Methodology

How SQL Formatting Works

AnyTool formats SQL with the tokenizer-based sql-formatter library, which supports 17 dialects (Postgres, MySQL, MariaDB, SQL Server/T-SQL, PL/SQL, BigQuery, Snowflake, Redshift, SQLite, DuckDB, Spark, ClickHouse, Trino, DB2, N1QL, and standard SQL). Because it tokenizes rather than using regex, it correctly handles subqueries, CTEs, CASE expressions, and window functions, and preserves -- and /* */ comments and string literals. Options control keyword/identifier/data-type case and indentation, with a minify mode. The library is bundled (no runtime CDN) and runs in-browser, so queries are never uploaded.
