    This can be accomplished by opening Constraint Manager and selecting File > Import > Worksheet File.
    There are three different file types acceptable to import; Text (tab delimited), Formatted Text (Space delimited) and CSV (Comma delimited).
    All three formats can be exported from an Excel spreadsheet.
    An example of a tab delimited Excel output for importing into the Net > Routing > Total Etch Length constraint is:

    Design:board_name                                                                
    Net:CLOCK    TEST_CSET    20            55                              

    For this example, the tab delimited fields consist of:
    Col A                 Col B         Col C        Col D    Col E    Col F
    Net:Netname    Ref Cset    Min value                            Max value

    Notes:
    - If a field is blank, a column must still be present in the Excel spreadsheet as a placeholder.
    - The design "board_name" must match the name of the .brd file

    Hope this helps.
    Tomo
