Learn the shortcuts for the tool you choose. It speeds up debugging significantly. 2.Validate Before Formatting:Sometimes a minified JSON string is hard to read. But if it’s invalid, beautifying it won’t help. Run the validation check first. Fix the errors, then format. 3.Keep Raw Data Local:If you’re dealing with sensitive production logs, ensure the tool you select has a "Clear Input on Exit" feature. Some basic tools keep data in memory longer than necessary.Also, consider integration.
