If your worksheet is set up properly, but you still can not import, you may have a structural problem. We recommend that you try to save it again using the standard Excel format. See how.

Some settings cannot be modified in the data file or import file during the data import so the dashboards can work properly. For instance:

  • You cannot add new columns between already imported columns:
    • New columns must be added at the end of the file;
  • Columns titles cannot be modified after the first import:
    • The columns nicknames can be modified in Input Data Format, but the dashboard's objects created previously will keep the previous nickname;
    • You must remove and add the column to update the dashboard's object nickname;
  • The columns cannot be removed from the file after the first import;
  • The columns position cannot be modified after the first import;
  • The columns data type (text, value, date) cannot be modified after the first import;
