The article, authored by 'Rajeev Pentyala', explains the process of utilising the ParseJson function to parse JSON data and bind it to a Gallery control within a Microsoft Canvas app. This process is illustrated through a scenario where a JSON string has been created containing a collection of 'Student' objects. Each object has properties such as Name, Mobile, Email, and City.
- The JSON string is read and parsed into a collection.
- This collection is then bound to the Gallery control.
- The author provides an example involving a JSON string of students generated by ChatGpt, with an alternative suggestion to use ObjGen website for the JSON generation.
- The ParseJson function is then used to parse this JSON string into a collection. A Text control is added to a new Canvas App and the JSON string is pasted into it.
- The TotalStudents variable captures the count of student records in the JSON string using the CountRows and UpdateContext functions.
- Finally, the JSON collection data are loaded into a PowerFx collection, which is then mapped to a Gallery control in the Canvas App.
