JSON tools
Format, validate, diff and convert JSON
JSON is the default wire format for almost every API, config file and log pipeline, which means engineers spend a surprising amount of time reading it. These tools make that faster: pretty-print, validate with precise error positions, minify for transport, diff two payloads and convert to and from YAML.
