Why SQL formatting matters
Unformatted SQL is notoriously hard to read — a complex query crammed onto one line can be nearly impossible to debug. Consistent formatting makes queries easier to understand, review, and maintain. It is especially important in team environments where multiple people read the same queries.
SQL dialect differences
While core SQL is standardized, each database has extensions and syntax quirks. MySQL uses backticks for identifiers, PostgreSQL uses double quotes, SQL Server uses square brackets. Selecting the correct dialect ensures the formatter handles these correctly.
Common SQL formatting conventions
Keywords in uppercase (SELECT, FROM, WHERE), table and column names in lowercase or snake_case, each major clause on its own line, subqueries indented, JOIN conditions clearly aligned.
Frequently Asked Questions
Does the formatter validate my SQL for errors?
It formats based on syntax rules but does not execute the query, so it cannot catch runtime errors like wrong table names or type mismatches.
Can I format very long queries with many JOINs?
Yes. The formatter handles arbitrarily complex queries including multiple CTEs, nested subqueries, window functions, and many JOIN clauses.
Is my SQL saved or sent to a server?
All formatting runs in your browser using the sql-formatter library. Your queries are never sent to any server. History is saved locally in localStorage.
