SQL Formatter FAQ
What does an SQL formatter do?
It rewrites a query with consistent indentation, line breaks, and keyword casing so the structure is easy to read — one clause per line, indented subqueries, and aligned joins. It only reshapes layout, not the query itself.
Does formatting change my query's results?
No. The formatter only changes whitespace, indentation, and keyword casing for readability. The database parses the formatted query the same way, so it returns exactly the same rows as the original.
Which SQL dialects are supported?
You can format Standard (ANSI) SQL, MySQL, PostgreSQL, MSSQL (T-SQL), and Oracle (PL/SQL). Pick the dialect that matches your database so dialect-specific syntax is handled correctly.
Can I keep or change my keyword casing?
Yes. Set Keywords to "Preserve" to leave casing untouched, or choose UPPER or lower to normalize every keyword to a single style across the query.
Are my queries sent to a server?
No. All formatting happens locally in your browser. Your SQL is never uploaded, logged, or stored, so it is safe even when queries reference sensitive schema or data.
Can it format multiple statements at once?
Yes. Paste a script containing several statements separated by semicolons and each one is formatted in place, keeping the overall structure of the file intact.
What happens if the SQL has a syntax error?
If the input cannot be parsed for the selected dialect, the tool shows an error message instead of producing broken output. Fix the reported issue, or try a different dialect, and the formatted result reappears.
