Tips & best practices
- Keep a small sample of your formatting handy — testing the options on a short input is faster than reworking a large one.
- Use the copy and download actions instead of selecting text manually; they preserve formatting exactly.
- Bookmark SQL Formatter so the workspace is one keystroke away during your next session.
- Format formatting before diffing or committing it — consistent formatting keeps reviews focused on real changes.
- Use SQL Formatter alongside your editor: paste, transform, copy back, and skip writing a throwaway script.
Common mistakes to avoid
- Pasting partial formatting and assuming the result is wrong — always include the full input.
- Ignoring the status messages in the workspace; they explain exactly what went wrong and where.
- Uploading sensitive formatting to random online services — SQL Formatter never needs to, because it runs on your device.
- Copying formatting out of a terminal with wrapped lines, which silently corrupts the input.
- Trusting a transformed result without re-validating it once more before shipping.
