Data load with Excel file

[louise119]

Hi,
I'm trying to load data into QlikSense using an excel file.
So, I have a question about the behavior of data loading when there is a differential update.
If the file name is the same, it was overwritten.
I wanna get the data like incremental update data.

Thank you.

I am not sure you can really do differential reloads with Excel, in my experience i have never been in the position where it was even worth considering.

Thank you.
I'm facing a problem that if there is data that I want to add to the data that I originally loaded, the original data will disappear because the file will be overwritten.

I would like to add data so that the data once loaded is still memorized by qlik and added as a delta.
