How do I paste date/time data from Excel
In SigmaPlot 7.1 and higher, you can simply copy and paste Excel date/time cells into SigmaPlot and they will correctly convert to SigmaPlot calendar dates and times.
However, in earlier versions of SigmaPlot, you must first change your Excel cell display to the standard date and time delimiters recognized by SigmaPlot during date and time data entry (typically month/date/year).

The delimiter used for date separations can be determined by your Windows regional settings.
