JSON-Splora - GUI for editing, visualizing, and manipulating JSON data

•    Javascript

---

JSON-Splora is a GUI for editing, visualizing, and manipulating JSON data with jq or JavaScript. The editor is a JavaScript editor, and the input is parsed as json5. This allows for comments as well as a relaxed JSON input format. Once the editor has valid JSON, an input window will appear below, allowing you to manipulate the object with JavaScript or jq. A panel will appear to the right with the output, and updates live as the input or filter changes.

fast-json-stringify - 2x faster than JSON.stringify()

•    Javascript

---

fast-json-stringify is significantly faster than JSON.stringify() for small payloads. Its performance advantage shrinks as your payload grows. It pairs well with flatstr, which triggers a V8 optimization that improves performance when eventually converting the string to a Buffer. Build a stringify() function based on jsonschema.

json-schema - Ruby JSON Schema Validator

•    Ruby

---

This library is intended to provide Ruby with an interface for validating JSON objects against a JSON schema conforming to JSON Schema Draft 4. Legacy support for JSON Schema Draft 3, JSON Schema Draft 2, and JSON Schema Draft 1 is also included. Please be aware that the upgrade to version 2.0.0 will use Draft-04 by default, so schemas that do not declare a validator using the $schema keyword will use Draft-04 now instead of Draft-03. This is the reason for the major version upgrade.

Editor.js - A block-styled editor with clean JSON output

•    Typescript

---

Editor.js is a Block-Styled editor. Blocks are structural units, of which the Entry is composed. For example, Paragraph, Heading, Image, Video, List are Blocks. Each Block is represented by Plugin. We have many ready-to-use Plugins and a simple API for creating new ones. Classic WYSIWYG-editors produce raw HTML-markup with both content data and content appearance. On the contrary, Editor.js outputs JSON object with data of each Block.

JSV - A JavaScript implementation of an extendable, fully compliant JSON Schema validator.

•    Javascript

---

A JSON validator is a program that takes JSON data and, with a provided schema, will ensure that the provided JSON is structured in the way defined by the schema. This ensures that if validation has passed, the JSON instance is guaranteed to be in the expected format. It will also provide an explanation on why a particular instance failed validation. There is no one way to validate JSON, just like there is no one way to validate XML. Even the JSON Schema specification has gone through several revisions which are not 100% backwards compatible with each other. To solve the issue of using numerous schemas already written to older specifications, JSV provides customizable environments to validate your JSON within.
