If you are using Konstru for Excel you might wonder: Where should I put all my additional calculations to round Forces for example? You can keep them on the same spreadsheet if you want to but please make sure the header field remains empty. As soon as the header field is filled out it will be the title of a new attribute and the value for each element will be the rows cell value. So if you do not want to upload your rounded values as a new attribute, just keep the header cell empty. Or do you calculations on an entirely different spreadsheet and link across. This is always safer.
