Can Flow be used to update a few specific columns in an Excel file that is stored in SharePoint?

I am new to flow and trying to figure it out.   I have 2 excel files stored in a SP library.  I want to grab rows from one file and update those that don't exist in the other file.   I did create named tables in each excel file but they are not SP lists.   Having a hard time with this... any help will be greatly appreciated.

Have a look under the excel actions you should find what you need there.


You are going to have to get all rows from the first file and then check the second file and if it does not exist use the create row action

Hi @MelGen ,


You need to create a key column (not null and have a unique value) in the two Excel tables to correspond to the rows in the two tables, in order to update the table.

  • Use Filter Query to filter out whether there are rows in the current File1 in File2, according to the ID field.
  • If the result of the length() function is 0, a new row is inserted in File2.

Hi, I got the flow to run successfully. However, I do not see the new rows in the table2 that I was trying to update.   Any ideas on how to I can determine where they went?  I tried to paste in the screen shot of the flow but its not letting me copy it in here.

I apologize for not responding. I was away and there wasn't any internet.   The following are the screen shots of the flow I built based on your suggestions.  As it indicates it was successfully but the excel file (file2) was not updated with the rows from file 1 that didn't exist in file 2.   I'm not sure how to troubleshoot this.   Any help with be appreciated....
