SQL Formatter FAQ
Quick answers about formatting SQL, minifying SQL, and using this tool safely.
What does a SQL formatter do?
A SQL formatter makes a query easier to read by adding line breaks, indentation, spacing, and consistent keyword styling.
What is a SQL minifier?
A SQL minifier removes extra whitespace and line breaks so a query can fit into a compact one-line format. This can be useful when embedding SQL in code or configuration files.
Does this tool run SQL queries?
No. This tool formats text. It does not connect to a database, run SQL, validate permissions, or execute queries.
Is my SQL uploaded to a server?
This version runs in your browser. Still, avoid pasting passwords, credentials, private customer data, proprietary production queries, or sensitive information into any online tool.
Is this formatter fully dialect-aware?
This first version includes dialect selection and dialect-related keyword support, but it is still a lightweight browser-based formatter. More advanced dialect handling can be added later.
Format, study, and practice SQL
