Jsonparser

Features

JSON Parsers - Parses JSON without requiring a schema, offering fast field extraction and modification by key path.
Schema-Free Parsers - Parses JSON directly from byte slices using a deterministic state machine without requiring predefined structs or type schemas.
Typed JSON Coercers - Coerces a JSON value into a Go string, integer, float, or boolean and reports an error on type mismatch.
JSON Value Access Interfaces - Inserts, updates, or removes values at specific key paths within an existing JSON byte slice without full deserialization.
JSON Value Modifiers - Provides in-place insertion, update, and deletion of values at specified key paths within JSON byte slices.
JSON Key Path Lookups - Navigate a JSON structure by a sequence of keys and return the raw bytes and type of the matched value.
Single-Pass Multi-Key Extractors - Extracting several distinct fields from a JSON payload in a single scan to minimize parsing overhead.
Lazy Extraction - Defers type coercion and value conversion until the caller explicitly requests a typed result.
Runtime Structure Inferrers - Infers JSON structure and value types at runtime without requiring a predefined Go struct or schema.
Zero-Copy Parsing - Parses JSON directly from the input byte slice without allocating intermediate strings or objects.
JSON Byte Range Modifiers - Modifies JSON by locating a value's byte range and overwriting it directly in the source slice.
JSON Path Navigation - Navigates nested JSON objects and arrays by a dot-separated key path to retrieve raw values or typed data.
JSON Key Path Extractors - Retrieves values from JSON by dot-separated key paths, returning raw bytes and type information.
Path-Based Value Inserters - Inserts or updates a value at a given key path inside an existing JSON byte slice.
JSON Token Scanners - Provides a deterministic state machine that walks JSON tokens to track nesting depth and structural boundaries.
Path-Based Tree Traversers - Navigates nested JSON by following a dot-separated key path through the parsed token stream.
Spatial Key-Value Extraction - Extracts several key paths from a JSON payload in a single scan, calling a callback for each found value.
JSON Array Iteration - Walks each element of a JSON array sequentially, invoking a callback with the element's raw value and detected type.
JSON Object Iteration - Walks each key-value pair of a JSON object and calls a function with the key, value, and type.
Callback-Driven Iterators - Walks through JSON arrays or objects element by element, processing each value or key-value pair with a callback function.
JSON Key Removals - Delete a value at a specified key path from an existing JSON byte slice.
Multi-Key Extractors - Ships a single-pass multi-key extraction feature that scans a JSON payload once to collect values at several specified paths.
JSON Processing - Fast JSON parser.

gjson is a Go JSON parser designed for schema-less reading and value extraction. It allows for the retrieval of specific data from JSON documents using dot-notation paths without requiring the definition of predefined Go structs. The library provides tools for path-based querying, including the use of wildcards and index-based queries to locate data within objects and arrays. It also functions as a JSON lines processor, treating multi-line documents as arrays to iterate and query individual entries. Additional capabilities include converting JSON values into native Go types such as strings,

VBA-JSON is a library designed for parsing and serializing JSON data within Visual Basic for Applications environments. It functions as an office automation data library, enabling legacy Microsoft Office applications to process structured data and interact with modern web services. The tool converts raw JSON text into native objects and collections, allowing developers to access and manipulate data using standard indexing and iteration methods. It also performs the reverse operation, transforming native language structures into JSON-compliant strings for exchange with external systems. By ha

simdjson is a high-performance, header-only C++ library designed for parsing, querying, and serializing JSON data with minimal memory overhead. It functions as a hardware-aware data processing engine that leverages vector instructions to achieve gigabyte-per-second parsing speeds. By detecting host processor capabilities at runtime, the library automatically selects the most efficient instruction sets to accelerate structural analysis and validation. The library distinguishes itself through a focus on extreme efficiency and resource management. It utilizes memory mapping and padded buffer ali

This is a Rust serialization library for converting data structures to and from JSON strings and byte streams. It is built as a framework within the Serde ecosystem, providing both a strongly typed parser for compile-time safety and a recursive value tree for manipulating JSON data without a predefined schema. The project supports both typed and untyped processing. It can map JSON data into specific Rust types for schema conformity or parse input into a flexible, schemaless representation. It also includes macro-based utilities for the dynamic construction of JSON objects.
