This sample shows how to read and write into an Excel document stored in your OneDrive for Business account by using the Excel REST APIs.
This sample requires the following:
-
Determine your ASP.NET app's URL. In Visual Studio's Solution Explorer, select the Microsoft-Graph-ExcelRest-ToDo project. In the Properties window, find the value of SSL URL. Copy this value.
-
Navigate to the the Azure portal - App registrations to register your app. Login using a Work or School Account.
-
Select New registration. On the Register an application page, set the values as follows.
- Set Name to Microsoft-Graph-ExcelRest-ToDo.
- Set Supported account types to Accounts in any organizational directory.
- Leave Redirect URI empty.
- Choose Register.
-
On the Microsoft-Graph-ExcelRest-ToDo page, copy and save the values for the Application (client) ID.
-
Select Certificates & secrets under Manage. Select the New client secret button. Enter a value in Description, select any option for Expires and choose Add.
-
Copy the client secret value before leaving the page. You will need it in the next step.
- Open Microsoft-Graph-ExcelRest-ToDo.sln file.
- In Solution Explorer, open the Web.config file.
- Replace ENTER_YOUR_CLIENT_ID with the client ID of your registered Azure application.
- Replace ENTER_YOUR_SECRET with the key of your registered Azure application.
- Press F5 to build and debug. Run the solution and sign in with your organizational account. The application launches on your local host and shows the starter page.
Note: Copy and paste the start page URL address http://localhost:21942/home/index to a different browser if you get the following error during sign in: AADSTS70001: Application with identifier ad533dcf-ccad-469a-abed-acd1c8cc0d7d was not found in the directory.
- Choose the
Click here to sign inbutton in the middle of the page or theSign inlink at the top right of the page and authenticate with your Office 365 account. - Select the
ToDoListlink from the top menu bar. - The application checks to see if a file named
ToDoList.xlsxexists in the root OneDrive folder of your O365 account. If it doesn't find this file, it uploads a blankToDoList.xlsxworkbook and adds all of the necessary tables, columns, and rows, along with a chart. After finding or uploading and configuring the workbook, the application then displays the task list page. If the workbook contains no tasks, you'll see an empty list. - If you're running the application for the first time, you can verify that the application uploaded and configured the
ToDoList.xlsxfile by navigating to https://yourtenant.sharepoint.com, clicking on the App Launcher "Waffle" at the top left of the page, and then choosing the OneDrive application. You'll see a file named ToDoList.xlsx in the root directory, and when you click on the file, you'll see worksheets named ToDoList and Summary. The ToDoList worksheet contains a table that lists each "to-do" item, and the Summary worksheet contains a summary table and a chart. - Select the `Add New' link to add a new task. Fill in the form with the task details.
- After you add a task, the app shows the updated task listing. If the newly added task isn't updated, choose the
Refreshlink after a few moments.
- Choose the `Charts' link to see the breakdown of tasks in a pie chart that was created and downloaded by using the Excel REST API.
