Frequently Asked Questions

FAQs about SQL Minifier

Are SQL comments removed?

Yes. Both single-line comments (-- comment) and multi-line block comments (/* ... */) are stripped during minification.

Will the minified SQL still execute correctly?

Yes. Minified SQL is functionally identical to formatted SQL — databases parse both the same way.

Is this useful for embedding SQL in code?

Yes. A single-line SQL string is easier to embed in string literals in JavaScript, Python, or other languages without multiline string concerns.

Does it affect string literals inside the query?

Whitespace inside quoted string values (e.g. WHERE name = "John Doe") is preserved. Only whitespace outside string literals is collapsed.

Is my data safe?

All processing runs in your browser. No SQL is ever sent to a server.
