TypeScript's 1:1 validator, optimized from editor to runtime.
ArkType is a runtime validation library that parses optimized validators from familiar, type-safe syntax.
It can be used to check external data like JSON payloads or form submissions at the boundaries of your code (similar to Zod or Yup).

JSON is everywhere on the Internet. Servers spend a lot of time parsing it. The simdjson library uses commonly available SIMD instructions and microparallel algorithms to break speed records.
The agents.json Specification is an open specification that formally describes contracts for API and agent interactions, built on top of the OpenAPI standard.

A super fast CLI tool to decode and encode JWTs built in Rust.
jwt-cli is a command line tool to help you work with JSON Web Tokens (JWTs). Like most JWT command line tools out there, you can decode almost any JWT header and claims body. Unlike any that I've found, however, jwt-cli allows you to encode a new JWT with nearly any piece of data you can think of. Custom header values (some), custom claim bodies (as long as it's JSON, it's game), and using any secret you need.
This page describes the JSON Lines text format, also called newline-delimited JSON. JSON Lines is a convenient format for storing structured data that may be processed one record at a time. It works well with unix-style text processing tools and shell pipelines. It's a great format for log files. It's also a flexible format for passing messages between cooperating processes.

Online JSON Toolkit is a powerful, all-in-one tool that streamlines your JSON workflows. Whether you're developing or testing APIs, Online JSON Toolkit makes handling JSON data faster, more efficient, and user-friendly.
Giving types to jq. JQ is a successful tool for json manipulation.
JQ has a problem though, it's errors are kind of hard to decipher. When you start creating some internal data as part of some larger transformation, it might be hard to pinpoint the source of an error. That is because JQ doesn't keep track of the input data flow, it merely interprets it. So, when jq has an error, it is local.
BSON, short for Binary JSON, is a binary-encoded serialization of JSON-like documents. Like JSON, BSON supports the embedding of documents and arrays within other documents and arrays. BSON also contains extensions that allow representation of data types that are not part of the JSON spec. For example, BSON has a Date type and a BinData type.
MinerU is a tool that converts PDFs into machine-readable formats (e.g., markdown, JSON), allowing for easy extraction into any format. MinerU was born during the pre-training process of InternLM. We focus on solving symbol conversion issues in scientific literature and hope to contribute to technological development in the era of large models. Compared to well-known commercial products, MinerU is still young. If you encounter any issues or if the results are not as expected, please submit an issue on issue and attach the relevant PDF.
