How can I format SQL online for free?

Paste your query into the "SQL query" box above, choose your dialect, and run the tool — formatting happens instantly in your browser with nothing uploaded. It is free and needs no signup.

What does a SQL beautifier do?

A SQL beautifier rewrites a flat or minified query with consistent line breaks, indentation, and clause layout so it is easy to read and debug. This tool does exactly that and never changes your table or column names.

How do I pretty print SQL with proper indentation?

Paste the query, select your dialect, and run the tool — it breaks each clause onto its own line with two-space indentation. Keyword case is preserved as you typed it.

Does this work as a MySQL formatter?

Yes — choose "MySQL" from the Dialect list and the query is formatted with the engine's MySQL grammar, which understands MySQL-specific syntax like LIMIT and backtick identifiers.

Can it format PostgreSQL queries?

Yes — select "PostgreSQL" as the dialect. The engine's PostgreSQL grammar handles Postgres syntax such as double-quoted identifiers and its join/cast forms.

Will the formatter change my query logic?

No. It only adjusts whitespace and line breaks — keywords keep their case and identifiers keep their spelling. It cannot fix broken SQL: invalid queries return a parse error instead of output.

What is Sql formatter?

SQL Formatter — Paste messy SQL and get clean, readable formatting in seconds. Free SQL formatter for PostgreSQL, MySQL, SQLite, BigQuery, T-SQL and Standard SQL.

Formatting is done entirely by the vendored sql-formatter OSS engine (its format() function with the selected dialect grammar); the wrapper only validates the input and maps the six UI dialect names to engine language names. Keyword case is preserved as typed and indentation uses two spaces. The engine parses with a nearley grammar, so syntactically invalid SQL returns a friendly parse error instead of output — it cannot repair broken queries.
