Important

Support for Machine Learning Studio (classic) will end on 31 August 2024. We recommend you transition to Azure Machine Learning by that date.

Beginning 1 December 2021, you will not be able to create new Machine Learning Studio (classic) resources. Through 31 August 2024, you can continue to use the existing Machine Learning Studio (classic) resources.

ML Studio (classic) documentation is being retired and may not be updated in the future.

Excel makes it easy to call web services directly without the need to write any code.

Steps to Use an Existing web service in the Workbook

  1. Open the sample Excel file, which contains the Excel add-in and data about passengers on the Titanic.

    Note

    • You will see the list of the Web Services related to the file and at the bottom a checkbox for "Auto-predict". If you enable auto-predict the predictions of all your services will be updated every time there is a change on the inputs. If unchecked you will have to click on "Predict All" for refresh. For enabling auto-predict at a service level go to step 6.
    • The Machine Learning Excel add-in will call Office add-ins store to load. If your organization ban access to Office add-ins store, you will see error when loading the add-in. For this case, please deploy the Machine Learning Excel add-in from Microsoft 365 admin center. Then invoke the add-in and add the web service manually by paste the URL and API key.

  2. Choose the web service by clicking it - "Titanic Survivor Predictor (Excel Add-in Sample) [Score]" in this example.

    Select Web service

  3. This takes you to the Predict section. This workbook already contains sample data, but for a blank workbook you can select a cell in Excel and click Use sample data.

  4. Select the data with headers and click the input data range icon. Make sure the "My data has headers" box is checked.

  5. Under Output, enter the cell number where you want the output to be, for example "H1" here.

  6. Click Predict. If you select the "auto-predict" checkbox any change on the selected areas (the ones specified as input) will trigger a request and an update of the output cells without the need for you to press the predict button.
