HI @Zahid ,
Welcome to Microsoft Q&A forum and thanks for reaching out
Unfortunately there is no SANDBOX kind of application. But you should be able to use Azure Free trial subscription of $200 credit to create a data factory and use with few activities to explore. I just created a free trial account and I was able to create a Data factory and use it.
Other option is if you are a Visual Studio subscriber, you can use Microsoft Azure at no extra charge. With your monthly Azure DevTest individual credit, Azure is your personal sandbox for dev/test. You can provision virtual machines, cloud services, and other Azure resources. Credit amounts vary by subscription level. For more info please refer to this doc: Use Microsoft Azure in Visual Studio subscriptions
Hope this info helps. Let us know if you have further query.
