Splitting Query at null rows

[tchristy99]

I have excel files that are being dropped into a folder weekly. I am trying to use BI to pull them into a report, I don't have the ability to edit them before hand though. The stucture of these file are as follow:

Column1	Column2	Column3	Column4	Column5	Column6
rows of data
null	null	null	null	null	null
null	null	null	null	null	null
Column1	Column2	Column3
rows of data
null	null	null	null	null	null
null	null	null	null	null	null
Column1	Column2	Column3	Column4	Column5
rows of data

Is there anyway to split the query at the nulls? Or filter out everything below the nulls? I am interested in any full or partial ideas, because I am out of them.

Thanks

Hi @tchristy99 ,

I found this similar post you can refer to

Since you are working with a folder, I take it that at some point, you have a column of tables?  If so, let's say the table column name is "Data".  You can try:

FilteredNulls = Table.AddColumn(PriorStepName, "Filtered", each Table.SelectRows([Data], each [Column1] <> null))

Now the tables should each have been filtered to remove the nulls from each Column1 of your tables.

Hi @tchristy99 ,

You can try to convert them into tables in Excel first, so that three tables will appear when you import Power BI.

Select the table you want and press Ctrl+T to generate the table. .

Then you can directly get the two tables when importing Excel.

Hi,

Thanks for your response. I did consider that, but these files are being dropped in daily, so I need something on the BI side. It is very possible that its not possible.

@tchristy99 have you tried using remove rows and keep rows option. those option may help you in acheving the output that you are looking for. 

If above does not help you, can you share the screenshot of the final output basis the input data that you have shared above. thanks

Hi, 

Thanks for your quick response.

That won't work because the amount of rows changes from file to file. Above is a image of the data (with a lot of rows hidden). What i need is them in 3 different tables in Power BI.
