Adding Rows from One Excel File to Another

[SamDixey]

Hi all,

I'm looking to build a flow that saves a monthly excel file from Outlook to SharePoint, and then adds the rows from the excel file into a 'master' file.

So far I've managed to create a flow that saves the excel to sharepoint and converts the data within it to a table format (the master file is already in a table format).

The final step I'm struggling with is setting the flow up correctly to copy the data in each row across from the monthly excel to the master file. There is approximately 70,000 rows each month therefore it would need to add all of these across. Each of the columns in the monthly excel and the master file are identical (26 in total).

Any help would be greatly appreciated!

My current flow is below.
