In my first post about Excel Services and REST, I showed how to construct a simple REST URL pointing directly to a PNG in a workbook. This post was supposed to be about the discovery built into the Excel Services REST API. However, I got a couple of questions about what my previous post actually looks like visually when used inside SharePoint 2010 and so I decided to post about that today instead. People like shiny screenshots.. :)

In the previous post, I gave the following example of a REST URL:

http://server/_vti_bin/ExcelRest.aspx/Shared Documents/Bugs.xlsx/Model/Charts(‘PersonalBugChart’)

In this post, I will show how a similar URL is used to post a chart about my alleged bug status into a SharePoint blog and have the chart be tied directly to the Excel file in which it resides.

First off – here’s what the chart looks like in Excel:

If you click the image you will see that the chart is called “PersonalBugs”. The actual location of the file is at “http://tssrva/sites/sp2009/shared documents/bugs.xlsx”. That means that the link to the chart inside Excel would be:

http://tssrva/_vti_bin/ExcelRest.aspx/sites/sp2009/shared documents/Bugs.xlsx/Model/Charts(‘PersonalBugs’)

The next step would be to create a blog post in SharePoint – when creating the blog entry, you can choose the “Insert” tab from the ribbon and then choose “From Address”:

Once you click address, all you need to do is put in the URL to the chart:

Once you hit OK, you will immediately see the chart appear within the blog post editor:

Hitting the Submit button will post the blog entry:

The real neat part then becomes that as the workbook changes (due to external data being refreshed, the spreadsheet itself being modified and saved etc), everybody will see the changes directly on the blog the next time they come in!

I hope the shiny screenshots made everything clearer.

Next up: Discovery!!
