A useful example should help you decide what to preserve and what can safely change. These guides show reproducible input and output rather than a list of feature promises.
JSON / DATA INTEGRITY
JSON number precision: format and minify without rounding
Follow a large ID, a long decimal, 4.0, 1e+30, and -0 from source to formatted and minified output. Learn why preserving text tokens differs from preserving a JavaScript number value, and what syntax validation cannot prove.
Includes actual formatter output, an invalid example, duplicate-key warnings, and a repeatable check in the JSON tool.
