Frequently Asked Questions

Does this formatter change the execution logic of my query?

No. The formatter only adjusts whitespace, newlines, and indentation. The semantic logic, column references, and expressions remain identical.

Is my database query kept private?

Yes. All parsing is done locally in your browser session. Queries containing table names, column structures, or proprietary schemas are never sent to external servers.

Client-Side Security Guarantee: All operations are processed locally in your browser sandbox using web standards. We never record, send, or store your code, data payloads, or tokens on any server.
