JSON Tools
JSON is the default format for APIs, configuration files and logs, and most day-to-day JSON work comes down to a few jobs: making a payload readable, finding out why it does not parse, comparing two versions, and producing realistic test data.
These tools cover those jobs. Start with the JSON Formatter to validate and pretty-print a document, use JSON Compare to see what changed between two responses, and the JSON Explainer to understand an unfamiliar structure key by key. To move JSON into other formats, see the data converters.
