Today we are announcing general availability (GA) of a free Excel add-in that you can use with web services published from Azure Machine Learning. Excel has millions of users, and this add-in lets you combine the analytical and visualization powers of Excel with the predictive powers of an Azure ML web service.
You can use this add-in for request/response predictions or batch predictions, work in Windows or the browser, share workbooks with your co-workers, and call multiple web services all within a single Excel spreadsheet. I’ll highlight new features of the add-in in this post; meanwhile essential information about the add-in is available from this earlier post.
You can get started by clicking here and downloading the sample Excel workbook or downloading the add-in directly from the Office Store. You may use the add-in directly in the browser using Excel Online or open the file in Excel 2013 or later on Windows. Copy the file to your own OneDrive account if you want to edit it.
Alternatively, when you publish a web service in Azure ML Studio, you can download an Excel workbook from Studio that already has the add-in installed and connected to your web service, as shown below.
Get Real Sample Data
By downloading the Excel workbook containing the add-in from Studio, you also enable the sample data feature for web services which can be turned off in the web service configuration page. Enabling means a few rows from the dataset used to train the model are available, so others can easily know how to use the web service based on real data.
Click the “Use sample data” button to check it out.
Interact with Auto-Predict
To create a dashboard to showcase the web service, interactivity is key. By checking the “Auto-predict” box, any time an input value changes, the RRS call is made and the output is updated.
Jump Among Multiple Web Services
If your workbook contains multiple web services, the values you enter for output cells and parameters are saved. When you use another web service and come back to a previous one, you do not have to re-enter all that information.
Support Multiple Web Service Inputs with Header Options
We support one, multiple, or no inputs and outputs. Depending on your needs, you have the flexibility to decide whether you want to send your input with headers or your output should show headers.
This is important for those who only want to score a few rows in the middle of a data set. Inserting the results in the output data matrix should not include headers.
Many web services require input parameters such as connection strings to SQL DBs or storage accounts to make them as flexible as possible. By checking the “Mask this field?” box in the parameter list, the parameter value shows up as asterisks, so the connection string is not shown in clear text.
