A free online tool for merging, comparing, and validating JSON that runs in the browser so data remains client-side and no login is required. It helps developers, data engineers, and API integrators work with nested structures, arrays, and complex objects using a visual interface and selectable conflict-resolution algorithms to reduce manual errors when merging or cleaning JSON.
