Questions fréquentes
›Which SQL dialects are supported?
Standard ANSI SQL works across PostgreSQL, MySQL, SQLite, MS SQL and most others. Vendor-specific extensions may format imperfectly.
›Does it modify the query?
Only whitespace and case — keywords are uppercased by convention but the logic is identical to your input.
›Is my SQL sent to a server?
No — formatting happens entirely in your browser. Useful when working with sensitive queries.
›Can it format very long queries?
Yes — anything your browser can hold in memory. Multi-thousand-line queries work fine.
›Is the formatter free?
Yes — fully free, no signup.
