Choose a formatter by the problem you need to review
Formatters make structure visible without changing the underlying values. They are useful when a compact payload, query, or document is hard to inspect, but the formatted result should still be checked with the parser and database that will consume it.
Before you copy the result
Keep the original input, choose the closest dialect, and compare important whitespace, comments, identifiers, and encoding declarations. Formatting is a review aid, not a correctness or security approval.
- Use JSON and XML formatters to inspect nesting and syntax errors.
- Use SQL formatting to review joins and filters without executing a query.
- Minify only after you have kept a readable copy for debugging.
