JSON Editor, developed by VDT Labs, is an application designed to facilitate the creation, visualization, modification, validation, formatting, and saving of JSON documents. It includes a built-in HTTP client, supporting HTTP verbs such as GET, POST, PUT, DELETE, and HEAD, to facilitate the fetching and uploading of content, including binary data. Additional functionalities encompass multiple sibling selection, sorting capabilities, finding and replacing with regular expression support, and customization options for font and appearance. Notably, JSON Editor operates entirely locally on the user's computer, ensuring 100% privacy, as no data is sent outside the device. Provides a structured, error-proof interface for manipulating JSON data, allowing users to add, reorder, delete, copy, and paste items with ease. Enables direct interaction with raw JSON text, featuring syntax coloring, auto-indentation, and line numbers.
