Data showing up as "NULL"

[Anonymous]

Hi, I have 26 separate Excel files all with the same column headings and tab name. 

I loaded all of them into PowerBI via "Combine and Transform"

However, some of the columns that had data in the original Excel column is not showing up in PowerBI, (not all the rows in the certain column is showing nulls, only certain rows are nulls while some rows are showing its value).

Thanks.

Hi @Anonymous,

Based on my test, I cannot repdoruce your issue here. Could you please share your M code and a sample file to me to have a test if you don't have any Confidential Information?  Kindly upload your files to One Drive and share the link here.

BTW, please make sure you have expanded  the column by clicking the highlighted button as shown in the following similar screenshot, then check if all the columns appear.
