JSON Toolbox puts a whole JSON workbench in the browser

Field notes

The toolkit groups its operations by workflow rather than presenting one isolated converter: users can edit, inspect, reshape, compare, and generate outputs from JSON. The visible feature list includes record-level actions such as filtering, adding, selecting, renaming, and removing fields, alongside exports to XLSX and CSV and two-way YAML and XML conversion. It also claims local browser processing, while the interface advertises nine languages for generated type definitions and SQL statements containing CREATE TABLE and INSERT output.
