csv import this table is empty

u4us1923 · ‎09-16-2024

Hello Everyone ..

I download csv files from a system every week. Sometimes there is no data for that week. Therefore, if there is no data in that csv, PowerBI will say “this table is empty” for that week's files. How can I change the table to “zero” if there is no data in the csv file of that week. If there data it does nothing.

Column -> Argument /Filters/Count

Thank you !

Hi @u4us1923 ,

As a workaround, you can create a date table with full dates and then merge with your source data to fill in the missing dates.

Here’s a step-by-step guide to achieve this:

1.Create a list of all dates within the range: Refer to Create Calendar Table Using Power Query M Language (mssqltips.com)
2.Merge the list of dates with your data: Merge this list with your existing data to ensure every date within the range is represented.
3.Fill missing dates with zero quantity: Replace any missing quantities with 0.

Thank you for the reply .. but .. I don't want to create a new table. I also loaded data from csv... my question is different. Some weeks there is data for all but some weeks there is no data for http400 or http500. for example; If there is no data for http500 that week I want to create a new row http500 -> Count --> 0 (zero)
