FAQ
Is my SQL data secure? Yes. This tool processes everything locally in your browser. Your queries are never sent to a server, making it safe for sensitive production code.
Does it validate syntax? No. This is a beautifier, not a validator. While it can handle most scripts, it won't debug broken SQL or identify missing commas.
Can it handle large queries? It is optimized for standard development and debugging. For extremely large files (thousands of lines), performance will depend on your browser's processing power.
Why We Use Uppercase
SQL keywords are traditionally written in uppercase—a practice dating back to the era of monochrome monitors. Before modern IDEs offered syntax highlighting, all-caps was the only way to distinguish language commands from table and column names.
Pro Tip: SQL was originally titled "SEQUEL" (Structured English Query Language) at IBM in the 1970s. While the name was shortened for trademark reasons, the original pronunciation remains the industry standard today.
