Remove duplicates in Excel Table or Delete all rows in Excel table.

[Alan-Hossack]

Hi,

I have a flow set up to combine the data from tables in 6 separate excel workbooks into one 'master' table in another workbook.

I have no issues getting the data in or adding it to the table, but I need to do one of the following to the 'master' table:

1. Remove all rows/data from table (at the start of Flow); or
2. Remove all duplicates from table (at the end of Flow)

Has anyone done something similar or have some pointers on what & how I could accomplish this?

Thanks!

Hi @Alan-Hossack ,

Remove all rows/data from table at the start of Flow could be easily achieved using the following configuration.

Please check the image for a reference.

Note: If you have more than 256 rows, you need to set Top Count to its maximum value.

Best regards,

One problem Iran into was that the Flow would error if the table had a filter applied to it. Clearing the filter fixed the issue though.

"statusCode": 404,

"message": "Resource not found"

I found this to be SUPER confusing, but here is the pain I went through, hopefully it will help someone else.  I noticed in the "Apply to Each" step, there is a field where you select the output from the previous operation.  There are 2 options (I have no idea why):  List of Items (List of Items), and value (List of Items).  When I pick the first one, it fails with the error:  The execution of template action 'Apply_to_each_2' failed: the result of the evaluation of 'foreach' expression '@body('List_rows_present_in_a_table')' is of type 'Object'. The result must be a valid array.

However, when I pick value (List of Items), it works.  OK Microsoft, why do you put something in there that doesn't work?
