Applies to: Excel 2016

This task pane add-in shows how to load data from an external service such as by using the GitHub Search APIs in Excel 2016. It comes in two flavors: code editor and Visual Studio.

The simplest way to deploy and test your add-in is to copy the files to a network share.

1. Host the files from the Code Editor Proj by using a server of your choice.

2. Edit the <SourceLocation> and <URL> elements of the manifest file so that it points to the hosted location from step 1. (for example, https://localhost/ExternalDataGitHub/Home.html)

3. Copy the manifest (ExternalDataGitHubManifest.xml) to a network share (for example, \\MyShare\MyManifests).

4. Add the share location that contains the manifest as a trusted app catalog in Excel.

   a. Launch Excel and open a blank spreadsheet.

   b. Choose the File tab, and then choose Options.

   c. Choose Trust Center, and then choose the Trust Center Settings button.

   d. Choose Trusted Add-in Catalogs.

   e. In the Catalog Url box, enter the path to the network share you created in step 3, and then choose Add Catalog.

f. Select the Show in Menu check box, and then choose OK. A message appears to inform you that your settings will be applied the next time you start Office.

5. Test and run the add-in.

   a. In the Insert tab in Excel 2016, choose My Add-ins.

   b. In the Office Add-ins dialog box, choose Shared Folder.

   c. Choose External Data GitHub Sample>Insert. The add-in opens in a task pane as shown in this diagram.
