I have .csv file which holds close to 1million records.How to identify it has loaded all data

Hi All,

I have Tableau Dashboard which I am working on which has close to 1 Million records when I open file independently as .csv file it wont load fully. I am building Tableau dashboard as source text file(.csv). I wonder it's completely loading the data in Tableau environment. I have tried both Live and Extract option. Is there a way we can identify to know it's loaded fully. This file has fully loaded. Is there a way we can check all data is loaded in Tableau environment. Any inputs highly appreciated

Thanks

S
