  You can use several Read Excel operators to get your spreadsheets in, then Append, and Write Excel.

  Hi @sara20 you could use a Loop Files operator  with a Read Excel inside and and an Append and a Write Excel angt the end.
  You could copy this basic setup
  Inside the Loop Files you could do any type of data cleansing and filtering that you could need.
