Frequently Asked Questions
Is my data sent to a server when using the SQL Prettifier?
No. The SQL Prettifier is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
Which SQL dialects are supported for formatting?
The formatter supports standard SQL syntax along with specific Dialects like PostgreSQL, MySQL, SQLite, and T-SQL to format keywords, nested queries, and indentation.
Does the SQL formatter check for syntax errors?
It formats the query structure based on token layouts, but it does not execute validation checks against an active database schema.
Is it safe to format proprietary SQL queries here?
Yes. Since formatting occurs locally in browser memory, your tables, column definitions, and proprietary schema metadata are never leaked.
Does the SQL Prettifier store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the SQL Prettifier compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the SQL Prettifier work offline?
Yes. Once loaded, all code and assets required to run the SQL Prettifier reside in your browser cache, enabling offline use without an active network connection.
