Field notes
The homepage combines a paste-or-drop workspace with separate landing pages for individual jobs such as validation, repair, comparison, and conversion. Its query panel documents a constrained JSONPath-like syntax, including recursive keys, wildcards, and numeric comparisons, while the tree view reportedly virtualizes large inputs. The site also states that local history uses browser localStorage and that synthetic samples contain no real personal information.
