Project Siena – Create apps with Excel and PowerPoint skills

Siena apps are as easy as editing a document. You place some visuals on a canvas. You hook them up to your data. You customize how your app looks and works. Then, if you need special logic and intelligence, you write some Excel-like expressions. You can use your app immediately, or share it with colleagues or the world.

With Siena, you can conceptualize, validate and build your app ideas almost as fast as you can come up with them. And if your apps needs change tomorrow, updating your app is no problem. Open it. Change it. Share it again, and you’re off to do business.

Siena works well with corporate and web data and media content: SharePoint lists, Excel and Azure tables, RSS feeds and the gamut of RESTful services.

Siena apps are just HTML5 and JavaScript and are deployed and managed like any other Windows 8.x app. In fact, developers can open them up, see what’s there and, if needed, extend them in their favorite programming tools.

Install Siena, watch one of the how-to videos at, and then build the app that you’ve been imagining... in under an hour.

    How would I go about updating an Excel spreadsheet OnSelect of a button.

    So for example, I've pointed a text gallery to a table that I have in an Excel DataSource. Then when I select any of the gallery entries, I have a text box that is updated to show the content of the cell from the spreadsheet. I want to be able to edit the textbox text and then click a button to update it in the excel spreadsheet. What command would I use?

    Also, is there a command to add a new entry (row) into the excel table, based on values of textboxes on a view?
