Frequently Asked Questions

Common questions about using this free online sql formatter.

Why is uppercase keyword formatting standard in SQL? ▾
Uppercasing keywords (e.g. `SELECT`, `INNER JOIN`) visually separates database commands from user table and column identifiers, dramatically speeding up query comprehension and troubleshooting.
Does this formatter handle complex nested subqueries and CTEs? ▾
Yes. Common Table Expressions (`WITH ... AS`) and nested subqueries are indented into clean, readable hierarchical blocks.
Does formatting change the execution plan of my query? ▾
No. SQL database query optimizers ignore whitespace and formatting; formatted queries execute with the identical query plan and performance.
Is my database query sent to a server? ▾
No. Formatting runs entirely in your browser via client-side JavaScript. Private database schemas, table names, and query values remain completely confidential.
