You Have Questions? We’ve Got Answers

A Q&A with Eric Pearl

Eric Pearl is the Director of Platform Marketplace and Consulting at Imagine. We sat down to ask him a few questions about the Excel Add-in.

Hey Eric, first, can you give some background on what Imagine Apps are?

An Imagine App is our name for a small JavaScript program that provides access to the rich universe of Imagine data and analytics. These Imagine Apps are made with standard JavaScript that access modules allowing you to access your positions, query current and historical data related to those positions, utilize Imagine’s curves, create analytic functions, run risk tools, and more. We do not run the JavaScript inside a browser – it runs in a process on our servers, and has API access to our business logic and persistent store. You can learn more about our JavaScript API here.

So is the Excel Add-in an App?

No, our add-in is built incorporating two separate pieces of technology; Imagine Apps and Imagine’s REST API.  Imagine’s REST web services provides a standard web service interface to Imagine Apps. And, remember, the apps are just JavaScript. You can learn more about Web Services here, and Imagine’s REST web service here.  Our web service uses the language-independent data format JSON for passing and returning data. So what happens is that our add-in does a translation of inputs to JSON for the REST call, and translates the JSON results back out to a cell (or range of cells).  The bottom line is this—the IFP Excel Add-in seamlessly integrates Imagine with Excel.

Can you give us an example of how it works?

Sure! Our add-in provides an Excel UDF (User Defined Functions) named IMAGINE() which can be used like other Excel functions like AVERAGE() or SUM(). Below is a screenshot showing how to use IMAGINE() in a formula to invoke an Imagine App named myApp. (We also demonstrate this in our demo located here).

The IMAGINE() formula passes the user’s input (the contents of A1 and B1) to the function with the exported name getVolSurface in the Imagine App myApp. Naturally, inputs and outputs can include Excel cell ranges as well.

In addition to the IMAGINE() UDF, we also provide IMAGINE.VBA(), which is easier when you are writing macros or VBA. See our demo for an example of how this works.

Where can I get the App? What if I want to write my own App?

Want to write your own App? Great, more details on the process are included for you  here.  Rather have Imagine Consulting write the App for you? The Imagine Consulting team can do that—contact us at consulting@imagine-sw.com.
