JSON tools

JSON tools for formatting, validating, minifying, comparing, querying, and generating starter schemas.

Format, validate, query, compare, and inspect JSON from API responses, logs, configs, and webhook events.

Best workflow

Start with format or validate, then use JSONPath to extract a field or JSON Diff to compare a changed payload.
