Known Issues In Current Version

  • #1: Spreadsheet export in regions where a decimal point is a separator
    makes Excel put each line into the first column and not separate columns.
    Workaround: Use SynthInvent's View/CSV and save the file to the desktop, then Open in Excel and select .csv then select Commas as Separators in the option box. This mostly works but will require formatting of columns to get totals and alignments to appear correctly.
