How this tool handles the input

What you get
What the page gives back
Readable SQL text that can be copied or downloaded as .sql.
Keep in mind
Use the result responsibly
Formatting does not prove correctness, safety, authorization, index use, or query performance.

Verified data boundary
Source text stays on this page.
The published contract marks these tools as client-only processing. Nirmion uses the API only to confirm that this workspace is enabled in MySQL; source values and results are not sent to Flask.
