Json Data Objects
A fast, dual JSON parser for Delphi 2009+ with UTF8/UTF16 support, automatic object/array creation, and easy access modes.
What is Json Data Objects?
Json Data Objects is a JSON parser library for Delphi 2009 and newer. It enables Delphi developers to parse, create, and manipulate JSON data efficiently, with support for UTF8 and UTF16 encoding without conversion. It solves the need for a fast, native JSON handling solution in Delphi applications across Windows and Android platforms.
Delphi developers building applications that require JSON parsing or serialization, particularly those targeting Win32, Win64, or ARM Android environments.
Developers choose Json Data Objects for its dual parser performance, automatic object/array creation, and intuitive API that simplifies JSON handling in Delphi. Its support for multiple encodings and platforms makes it a versatile choice over basic or slower alternatives.
Overview
JSON parser for Delphi 2009 and newer
Use Cases
Best For
- Parsing JSON in Delphi Win32/Win64 applications
- Handling JSON data in Delphi Android projects
- Creating and serializing JSON objects with automatic structure management
- Working with large JSON files using progress callbacks
- Needing UTF8 and UTF16 JSON support without encoding conversion
- Integrating JSON with Delphi's Variant type system
Not Ideal For
- Projects primarily targeting iOS or macOS, where support is only 'may work' and not officially guaranteed.
- Applications requiring integrated support for multiple data formats like XML or YAML, as this library is JSON-specific.
- Teams using modern Delphi versions with built-in JSON libraries who prefer standard, vendor-supported solutions for simplicity and long-term maintenance.
Pros & Cons
Pros
Parses both UTF8 and UTF16 JSON without conversion, ensuring high-speed handling of different encodings as emphasized in the README's features list.
Automatically creates arrays and objects on access, reducing boilerplate code and simplifying JSON manipulation, as shown in the usage examples.
Offers easy access modes with implicit operators and typed properties (e.g., .S['key']), making it feel native to Delphi developers, as highlighted in the README.
Supports both compact and formatted JSON output modes, allowing developers to choose based on readability or size needs, demonstrated in the code snippets.
Cons
Officially supports only Win32, Win64, and ARM Android; MacOS and iOS are noted as 'may work', which introduces risk for projects targeting those platforms.
Lacks advanced JSON features like schema validation, streaming parsing, or deep integration with other data formats, which might be necessary for complex enterprise applications.
Automatic creation of objects and arrays on access can lead to increased memory usage in performance-critical scenarios, a trade-off for ease of use.
