We have found one software suitable in our database for this conversion.
xls to wdb conversion has been done in the past by users that needed to transfer spreadsheets between Microsoft Excel and Microsoft Works. Since the latter has been discontinued years ago, this conversion is not that common and to be perfectly honest, the only way how to do it nowadays, is with the original MS Works. You might still find it on abandonware websites, if you really need it.
