Changes in data once an excel file is uploaded

[Anonymous]

When I uploaded an excel file I noticed that "null" appeared in some random cells that previously had number data in it. I am unsure why this is happening and how to trouble shoot it. Thank you

Hi @Anonymous 

Can you check transform data option for this and check what are the steps applied on data?

1. Click on 

2. Copy the applied steps

probably there is something by default getting applied and needs to be analyzed

Thanks,
