Importing Fixed Price Items from CSV/Excel
You can import multiple fixed-price items to an invoice or invoice template from CSV/Excel or any other spreadsheet app. To do this, just copy-paste required lines from a spreadsheet application into an empty fixed price item in the invoice editor. The last column will be used as the amount.
Amount column should not contain any formatting, like spaces or commas as the thousands separator. And amount should have a dot as a separator for the fractional part.
