With the help of Zapier's automated workflows, users can connect two Microsoft Excel spreadsheets and set up an automatic workflow that copies new rows from one spreadsheet to another, keeping data accurate and up-to-date instantly. To start, a header row with labeled columns is required in both spreadsheets, and Zapier will need to know which columns to map for the data transfer. Users can create their own Zaps or use pre-made templates without coding knowledge, setting up triggers that start the workflow and actions that perform the desired task. Once set up, the Zap performs automatically whenever a new row is added to the first spreadsheet, sending it over to the second spreadsheet with minimal user intervention.
