• JSON String - The string containing the JSON to be deserialized. The JSON should be written without indents, and between double quotes. Strings inside the JSON should be written with single quotes. For example, the following JSON is valid: "{'TenancyName': 'Documentation', 'UsernameOrEmail': 'Documentation', 'Password': 'Documentation'}".
• JSON Sample - The JSON sample for the output structure. The activitiy converts this sample into a similar object which you can use during design time.

Exemple d’utilisation de l’activité Deserialize Json

The Deserialize Json activity is used for extracting data from JSON files and strings.

To exemplify how to use this activity, we have created an example that uses the Deserialize Json activity for extracting the age of a person from a JSON file.

Voici comment le processus d'automatisation peut être créé :

1. Ouvrez Studio et démarrez un nouveau Processus.
2. Drag a Sequence to the Workflow Designer.

   • Créez les variables suivantes :

     Nom de variable	Types de variables	Valeur par défaut
     JsonText	Chaîne de caractères (string)
     JsonObj	ObjetJ
     Age	ValeurGénérique

3. Drag a Read Text File activity inside the sequence container.
   • In the Properties panel, add the value "JsonString.txt" in the FileName field.
   • Add the variable JsonText in the Content field.
4. Add a Deserialize JSON activity after the Read Text File activity.
   • In the Properties panel, add the variable JsonText in the JsonString field and the variable JsonObj in the JsonObject field.
   • Select the value Newtonsoft.Json.Linq.JObject from the TypeArgument drop-down list.
5. Place an Assign activity under the Deserialize JSON activity.
   • Add the variable Age in the To field and the expression JsonObj.SelectToken("age").ToString in the Value field.
6. Drag a Write Line activity after the Assign activity.
   • Ajoutez la variable Age dans le champ Texte.
7. Run the process. The robot extracts the age value from the .json file and displays it in the Output panel.
