@Petar Novakovic Thanks for reaching out. You can leverage logic app workflow for the automation as per your business needs. Please review the limitations of the excel connector and verify if it fits as per your business needs. Once you have verified then you can leverage the List rows present in table to get the rows of your excel and then leverage the tokenized value as the column name to get the actual cell value. Now you can leverage the date and time function to get the hour part of your value and as per your business logic calculate the value using different function expression, control statement such as condition, loops etc in your workflow. To add a row, you can leverage Add a row into table action
Feel free to get back to me if you need any assistance.
