Developer Quick Tips
- Choose your indentation width (2 or 4 spaces) before formatting to match your team's SQL style guide.

- Paste SQL or upload.sql files directly; formatted output can be copied or downloaded as formatted.sql.
- Syntax errors are reported immediately, so you catch unparseable queries before they leave your browser.
- Format SQL as text only, no database connection, no query execution, all processing stays on your device.
Frequently asked questions
Does SQL Formatter upload my data to DevToolMate servers?
No. SQL Formatter runs entirely in your browser. Your input is never uploaded to our servers. All formatting happens locally on your device.
Is SQL Formatter free and do I need an account?
Yes, SQL Formatter is completely free with no account required. No login, no sign-up, no payment. Just paste or upload your SQL and format.
Does SQL Formatter execute my SQL queries?
No. SQL Formatter only transforms text for readability. It does not execute queries, connect to databases, or validate results. Formatting is a text-only operation.
Can I upload.sql files to format?
Yes. You can paste SQL directly or upload.sql files within browser size limits. The formatted output can be copied to clipboard or downloaded as a new.sql file.
How do I control indentation in the formatted output?
Before formatting, select your preferred indentation width (typically 2 or 4 spaces). The formatter will apply consistent indentation to nested blocks, joins, and subqueries.
What happens to my SQL after I close the browser tab?
Your input is cleared when you close the tab. DevToolMate does not store tool input on servers. Only your theme preference is saved locally in your browser.
