SQL Minifier

Collapses a SQL query onto one line and removes comments, so it can be embedded in a config file, a log line, or a shell command. Text inside string literals and quoted identifiers is preserved exactly, and spacing is only kept where removing it would change the query. Runs entirely in your browser — nothing is sent to a server.

FAQ

Is my query sent to a server?

No — this tool runs entirely in your browser.

Are comments removed?

Yes. A line comment would otherwise swallow the rest of the query once it is on a single line.

Is anything inside my strings changed?

No. String literals and quoted identifiers are copied verbatim.
