title: Power BI Desktop / data not loading
body: <p>I am trying to transforming and loading data from mongodb to power bi and currently facing an issue in loading the data. I have used mongosqld service to access the required collection and also defined a system dsn access point from the odbc driver. I am able to transform data and in my data in one of the column there are Tables as values in each row and it is been expanded while transforming the data before loading but due to some reasons after transforming when I'm loading the data it is not loading and taking a lot of time there are almost 70,000 documents in that collection but it is not able to load the data and gets stuck while loading. I think because of this transforming alot of columns are being added due to which it is not able to process all of it data based on my current system configuration.</p>
