Filter array

Hello Community,


I created a flow to update an Excel table depending on an ID (name DocID). The ID is a numeric.

I retrieve and transfer the data using a webhook, which contain a simple JSON body. In the next step I choose the action "List rows present in a table". Afterwards I try to compare and filter the ID getting from the webhook with the excisting IDs in the table. If the result ist empty, Excel should create a new row otherwise the excisting row should be updated. I also know that the returned IDs from Excel are in string format.

My filter array looks like that:


The expression of "value" is


And the comparison is

string(triggerBody()?['DocID']) is equal to  triggerBody(outputs('List rows present in a table')?['body'])
I submitted an excisting ID, so the flow should updated the Excel but instead a new row was created. The reason is that the returned array body is empty:

Thanks a lot.

This will return the whole list rows. If your excel Id column is called ID then you should try the below

Thanks a lot.

Unfortunately the problem still exist. And I found a second curiosity.

In the first picture you can see the data received by the webhook:


Afterwards the flow didn't find the ID, which is not correct due to the "filter array" condition and create a new row, which is logical correct. But this row is empty. All entries are "null":


But the should correspond to the data of the first picture.

This is the corresponding data assignment:
