How to choose the right json tools

Use these tools to inspect API payloads, validate configuration files, and move safely between readable JSON and compact transport formats.

Before you use a tool

  • Validate syntax before changing production configuration.
  • Format data before reviewing nested objects or arrays.
  • Minify only when a compact payload is more important than readability.

A practical workflow

Format or inspect a payload first, make the required change, validate it again, then use a minifier only for a final compact copy.
