I’ve just downloaded LabPlot and can get it to run but can’t open anything into a spreadsheet.
Any suggestions?
What do you mean with “can’t open anything into a spreadsheet”? You cannot import any data into the spreadsheet?
Helping out in the comments is not so comfortable. Would any other option listed on https://labplot.kde.org/support/ be feasible for you?
