How to Download and Use DBXJson.pas in Delphi
DBXJson.pas is a Delphi library that implements JSON (JavaScript Object Notation) data format and objects structure. JSON is a lightweight and easy-to-read alternative to XML for data interchange. It is widely used in web development and APIs.

In this article, we will show you how to download and use DBXJson.pas in Delphi 2010 or later versions. We will also provide some examples of parsing and generating JSON data using this library.
How to Download DBXJson.pas
DBXJson.pas is not included in the standard Delphi installation, so you need to download it from an external source. One of the most popular sources is GitHub, where you can find the latest version of the library maintained by fabriciocolombo [^1^]. You can either clone the repository or download the ZIP file containing the source code.
Another source is SourceForge, where you can find an older version of the library created by leon_kon [^2^]. This version may not be compatible with newer Delphi versions or JSON features, but it may work for some simple cases. You can download the ZIP file containing the source code from this site.
A third source is Microsoft Sway, where you can find a link to download DBXJson.pas [^3^]. However, this link may not be reliable or secure, so we do not recommend using it.
How to Use DBXJson.pas
After downloading DBXJson.pas, you need to add it to your Delphi project. You can do this by adding the file path to the Search Path option in Project Options. Alternatively, you can copy the file to your project folder or a common library folder.
To use DBXJson.pas in your code, you need to add DBXJSON to the uses clause of your unit. This will allow you to access the classes and functions defined in the library.
The main classes in DBXJson.pas are TJSONObject, TJSONArray, TJSONPair, TJSONString, TJSONNumber, TJSONTrue, TJSONFalse and TJSONNull. These classes represent different types of JSON values and objects. You can use them to create, manipulate and access JSON data in memory.
The main functions in DBXJson.pas are TJSONObject.ParseJSONValue and TJSONValue.ToString. These functions allow you to parse a JSON string into a TJSONValue object and vice versa. You can use them to read and write JSON data from files, streams or strings.
Examples of Using DBXJson.pas
Here are some examples of using DBXJson.pas in Delphi code:
Parsing a JSON String
uses
DBXJSON;
var
JsonStr: string;
JsonVal: TJSONValue;
begin
// A sample JSON string
JsonStr := '"name":"John","age":25,"pets":["dog","cat"]';
// Parse the JSON string into a TJSONValue object
JsonVal := TJSONObject.ParseJSONValue(JsonStr);
// Check if the parsing was successful
if JsonVal nil then
begin
// Do something with JsonVal
// ...
// Free JsonVal when done
JsonVal.Free;
end;
end;
Generating a JSON String
uses
DBXJSON;
var
JsonObj: TJSONObject;
JsonStr: string;
begin
// Create a new TJSONObject object
JsonObj := TJSONObject.Create;
// Add some pairs to the object
JsonObj.AddPair('name', 'John');
JsonObj.AddPair('age', TJSONNumber.Create(25));
JsonObj.AddPair('pets', TJSONArray.Create(TJSONString.Create('dog'), TJSONString.Create('cat')));
// Convert the object into a JSON string
JsonStr := JsonObj.ToString;
// Do something with JsonStr
// ...
// Free JsonObj when done
JsonObj.Free;
end;
