Dynamic Excel Dataset
Hello. Is there a good tool we can use to handle dynamic excel datasets (column name format might change, order of columns might change) before connecting it to Power BI? My client wants it that way, I have explained that we need to be specific and consistent in the format of excel sheets, so we will not encounter errors in our Power BI. But is there any solution for this dynamic dataset.
Thanks for the reply from rajendraongole1 , please allow me to provide another insight:
Hi LeonardBagos ,As far as I know, Power BI temporarily does not support direct synchronization of the data source after the change of the column name, if you change the name of the column in the data source, power bi or in accordance with the old column name to get the data in the data source, matching the new name of the column may appear an error message " The column 'columnname ' of the table wasn't found".
So when the data model changes, we can go to Power Query to manually refresh it.

Or go into the data source setting and clear all permissions - then recapture them.
