Import of Excel file

A standard excel file can be imported into Timeplan, however the first line of the excel file must be a description of the different columns. The column headings must have uniquely named names, in addition, a column must contain a date. The column must be named "Date".
It is also important that the cells to be loaded into Timeplan are not formulas or references to other places in the excel document, but real values. For example, it must not read "=D5+E5" in cell B2 in the example below, but the cell must contain the correct number "76".

Example of what the file might look like:
