Data Source Order

Hey,

Can somone help me in understanding why when I upload data to Power Bi its not in the same order as the excel file I used to upload the data?

Thanks

Data order is only a concept us humans care about. Databases don't care, and don't order the data. It is much more efficient (eg for multi threaded data loading) to load in what ever order makes sense at the time. All formulas are written assuming the order is. It important. If it is (eg ordinal date calculations), then you need to write a calculation that will handle that.

I will not give you bad advice, even if you unknowingly ask for it.

Many thanks for the reply.

I was worried since the order was not the same as in excel the data was somehow incorrectly rearranged especially since I saw lots of columns not showing any values but once i went in to edit queries the data was there and in the correct order. May just be a bug im not sure.

Thanks for the clarification

@akewander

Agree with Matt, That is not a bug but by design.

The viewing order in your case doesn't make sense, if you do care, just sort the data ordering by a specific column(s).
