Read web config file values in office addins office.js

Hi kishorimestry...

Generally this is not something that is Office Add-in specific. You would use the same approach as with a regular website.

For example, see ASP.Net: Read (Get) AppSettings Key Value from Web.Config file in JavaScript.

In terms of the manifest start URL, you can point it at any web-browsable page, it doesn't have to end with html.

So you can use an aspx or MVC view page. Alternatively, you can have an html/js/css page that makes an AJAX web service call to your own web API that returns you the setting.

Hi @dharmendr

I created the web excel Add-in project in visual studio this is not ASP.net project and there is the auto-generated web. config file so how can we access the value all you provided solution i used it not worked for me 

Can you guid me how can i used.

Hi dharmendr

What you provided is not safe because if I call API then secured data is also accessible.

Use JavaScript to read the value.

<appSettings>
    <add key="name" value="ASPSnippets"/>
</appSettings>
var appValue = '<%=ConfigurationManager.AppSettings["name"] %>';
