Comma-delimited and tab delimited CSV files can be opened directly with Excel, using the "Launch Excel" action and specifying the CSV file path.
However, this approach doesn't work for semicolon delimited CSV files, as Excel does not recognize semicolon as a valid delimiter.
A workaround would be to use the "Read from CSV File" action and select the semicolon as columns separator in the advanced tab.
Then, launch a blank Excel document and write the CSV table into cell A1.
Finally, save it in XLSX format.
