2.118 FAQ-1066 How do I copy and paste date-time data from MS Excel?

Last Update: 10/13/2020

You can copy date-time data from MS Excel and paste it into Origin but there are some things to watch for. The most important thing to note is that data in the Origin worksheet registers as either text or numeric.

  • If data are left-aligned in the worksheet, the data register as text.
  • If data are right-aligned, the data register as numeric.
  • Since correctly-formatted date-time data are stored internally as numeric, seeing left-aligned date-time data will be your first clue that something isn't correctly formatted.

Origin 2021 or Later

Beginning with Origin 2021, code changes make it easier to copy and paste date-time data from MS Excel to Origin. As long as date-time data are properly formatted in Excel, you should be able to simply copy the data in Excel, paste it to Origin and Origin should automatically format the column properly as date-time (again, if pasting results in left-aligned data, something isn't properly formatted).

Note that despite slight differences in Excel and Origin date-time notation, the date-time data in the above example are properly pasted to Origin, without need for configuring column Properties.

  1. You can confirm this by selecting the worksheet column in Origin, right-clicking and choosing Properties.
  2. You should see that the Format is set to Date or Time, and that Display or Custom Display show the proper date-time format (see Origin's Date and Time Format Specifiers).

  • Before data can be treated as date-time and analyzed and plotted correctly, the column Format must set to Date or Time and the correct date-time Display string must be specified.
