Loading data and creating visualizations directly from a web app on the fly

Fri, 01 Sep 2017 06:56:52 GMT

Hi,

Is it possible to directly load an excel file and plot visualizations directly from a web app using the Sense API? I would like to load the data and create visualizations on the fly without having to create a qvf file.

I have looked at the documentation regarding the Qlik Sense API but I believe it would require a qvf file with existing objects. There are a few documents to help create a new session app on the fly -

http://help.qlik.com/en-US/sense-developer/June2017/Subsystems/Mashups/Content/Howtos/create-session-app.htm

but it does not explain how to load an external data file directly into the new app.

Any help regarding this is appreciated.

So you basically just need to do Step 2 (define and set load script) and Step 3 (reload data and create chart) from the link you provided.

How to create the load script and load the external data is really up to you. I think that halyard.js‌ would be really handy here. It can read .csv files and create a load script.
