Excel to CSV will let you submit an Excel file to a Switch flow were it will be converted to CSV. It will accept Excel files with multiple sheets.
You have different options of delimiter for the columns.
A fast and useful plugin. We use it in conjunction with personalisation software and thus save ourselves the tedious and error-prone work via Excel. It is excellent that the workstation does not require Excel to be installed. The addon is worth the money and we recommend it.
Excel to CSV works exactly as advertised. It removes the need to save XLSX files to CSV prior to injection into a Switch flow. Well worth the subscription. I use it in several flows. No issues.
