N8n With google sheet

i want help guys with my workflow
i want my workflow to get rows from many tabs in google sheet and perform some data cleaning and then create new sheet with the new tabs

Wouldn’t it be cleaner to do the cleaning per tab? My experience is that if you keep the complexity low, the number of errors stay low. You can duplicate the clean data flow for each tab.
Alternatively, you can create a table with all the tab names, and loop through that list while cleaning per tab.
