Serialize JSON to a file. Serialize with JsonConverters. Serialize a DataSet. Serialize Raw JSON value. Serialize Unindented JSON. Serialize Conditional Property. Deserialize an Object. // read file into a string and deserialize JSON to a type Movie movie1 = JsonConvert.DeserializeObject. This sample deserializes JSON retrieved from a file. Mar 30, 2017  JSON (JavaScript Object Notation) is an efficient data encoding format that enables fast exchanges of small amounts of data between client browsers and AJAX-enabled Web services. This article demonstrates how to serialize.NET type objects into JSON-encoded data and then deserialize data in the JSON format back into instances of.NET types. Similarly, to include null values in serialization, we can call serializeNulls. The available options are listed here. In this quick article, we got an understanding of how to serialize various Java data types into a JSON file. To explore various articles on JSON, have a look at our other tutorials on this topic.

JSON is the standard data format that be used to save and transfer text data between programs. It is independent from programming language. Python provide built-in json module to process JSON string and Python object conversion. This article will give you some example.

PM Install-Package Newtonsoft.Json As an aside, I'm using JSON data for the first time with a recent prioject, and it's remarkably easy with the Newtonsoft stuff: serialize and deserialize a whole list of a custom class in one line of code each! What is Serialization? Serialization is the process of converting an object into a stream of bytes. In this article, I will show you how to serialize object to XML in C#. XML serialization converts the public fields and properties of an object into an XML stream. Open Visual Studio. Go to File-New-Project, Choose Console Application. Reading and writing BSON is also faster than JSON which makes it a superset of JSON. More information can be found in this link. JSON.NET supports reading and writing binary JSON (BSON). In this article we will use Netwonsoft.Json package to work with JSON Serialization and Deserialization operations.

1. JSON String And Python Object Conversion Overview.

Before you can use json module, you should import it first.

1.1 Convert Dict Object To JSON String.

  1. Create a dict object.
  2. Call json.dumps() method to get JSON string from dict object.

    Below is the output.

1.2 Convert JSON String To Dict Object.

  1. Create a JSON string.
  2. Call json.loads() method to return the python dict object.

    Below is the output.

2. Dump Python Dict To JSON File Or Load Dict From JSON File.

2.1 Dump Dict To JSON File.

  1. Call open method to get a file object.
  2. Call json.dump(dict_object, file_object) to save dict data to JSON file.

    When you execute above code, you can find the teacher_data.json file in current execution folder.

2.2 Load JSON File Data To Python Dict.

  1. Create a python file object by open method.
  2. Call json.load method to retrieve the JSON file content to a python dict object.

3. Python Class Instance Serialize And Deserialize.

Besides serialize/deserialize Python dict object between JSON string or file. We can also dump / load any Python class instance between JSON string or file.

3.1 Dump Python Class Instance To JSON String.

  1. Create a python class.
  2. Add a method which can return a python dict object based on the class instance.
  3. Call json.dumps(class_instance, default=self.teacher_to_dict) method and set the convert method name in step 2 to parameter default. If do not set the default parameter value, it will throw TypeError: Object of type ‘Teacher’ is not JSON serializable error.

3.2 Load JSON String To Python Class Instance.

  1. Create a python class.
  2. Add a method which can return a class instance from loaded python dict object.
  3. Call json.loads(json_string, object_hook=self.dict_to_teacher) method and pass the method name in step 2 to the object_hook parameter.

3.3 Dump Python Class Instance To JSON File.

It is similar with steps in 3.1. The difference is you should call json.dump(class_instance, file_object, default=self.teacher_to_dict) method.

3.4 Load JSON File String To Python Class Instance.

It is similar with steps in 3.2. The difference is you should call json.load(file_object, object_hook=self.dict_to_teacher) method.

Syntax

Description

The ConvertTo-Json cmdlet converts any object to a string in JavaScript Object Notation (JSON)format. The properties are converted to field names, the field values are converted to propertyvalues, and the methods are removed.

You can then use the ConvertFrom-Json cmdlet to convert a JSON-formatted string to a JSONobject, which is easily managed in PowerShell.

Many web sites use JSON instead of XML to serialize data for communication between servers andweb-based apps.

This cmdlet was introduced in Windows PowerShell 3.0.

Examples

Example 1

This command uses the ConvertTo-Json cmdlet to convert a GregorianCalendar object to aJSON-formatted string.

Example 2

This example shows the output from ConvertTo-Json cmdlet with and without the -AsArray switchparameter. You can see the second portion of the output is wrapped in array brackets.

Example 3

This command shows the effect of using the -Compress parameter of ConvertTo-Json. Thecompression affects only the appearance of the string, not its validity.

Example 4

This example uses the ConvertTo-Json cmdlet to convert a System.DateTime object from theGet-Date cmdlet to a JSON-formatted string. The command uses the Select-Object cmdlet to getall (*) of the properties of the DateTime object. The output shows the JSON string thatConvertTo-Json returned.

Example 5

This example shows how to use the ConvertTo-Json and ConvertFrom-Json cmdlets to convert anobject to a JSON string and a JSON object.

Parameters

-AsArray

Outputs the object in array brackets, even if the input is a single object.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Omits white space and indented formatting in the output string.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Specifies how many levels of contained objects are included in the JSON representation. The defaultvalue is 2.

Type:Int32
Position:Named
Default value:2
Accept pipeline input:False
Accept wildcard characters:False

Provides an alternative serialization option that converts all enumerations to their string representation.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Controls how certain characters are escaped in the resulting JSON output. By default, only controlcharacters (e.g. newline) are escaped.

Type:NewtonSoft.Json.StringEscapeHandling
Position:Named
Default value:Default
Accept pipeline input:False
Accept wildcard characters:False

Specifies the objects to convert to JSON format. Enter a variable that contains the objects, or typea command or expression that gets the objects. You can also pipe an object to ConvertTo-Json.
