In Nintex 2010, 2013 and 2016 for SharePoint (Standard version even) on-premise of course, there was a possibility to use Excel Services to query and work with the xlsx and xls files’ data. However, in Sharepoint Online there is no such powerful mechanism (well, there are Excel Services available via REST API, but it doesn’t provide that much functionality). Moreover Nintex products for SharePoint Online (neither Nintex Workflow Cloud nor Nintex for Office 365) don’t have any “OOTB” actions that would fill that gap. So in the end, there is no straightforward way to achieve it. So how can I import (and preferably automate it) data from XLSX file into SharePoint?

The most common workaround is to convert the xlsx file into a plain, csv file and then to work with the data from the file using collections (I will write about it in second post).

Recently I have realized, that there is a set of Excel actions in Microsoft Flow! All of us, who has SharePoint Online, has also a free version of Flow available.
