Splitting columns

[#1]

Hi,

i have a column full of dates with different time points in the date. Eg:

2020-01-31T11
2020-01-31T12
2020-01-31T13
2020-01-31T14
2020-01-31T15
2020-01-31T16
2020-01-31T17
2020-01-31T18
2020-01-31T19
2020-01-31T20
2020-01-31T21
2020-01-31T22
2020-01-31T23
2020-02-01T00
2020-02-01T01

but I want to split them into two separate columns: date and time. I'm a beginner so I'm still getting use to the software.

thanks!

You can use the Left, Substring, and or Right functions (found in the Character group in the formula window) to create 2 new columns, one with the date and the other with the hour (I am assuming the last two digits are the hour and the T just stands for time).  Then, make sure the date column yyyy-mo-day is formatted as a date.  So, to get the date you could use Left(current column, 10) and for the hour you could use Right(current column, 2).

I have attached you sample data table and have added 2 columns.  The formula I used for the first column is:

Informat( Substr( :Column 1, 1, 10 ), "Y/m/d" )

It was a pretty straight forward conversion, because the substringed data matched an existing Informat().

The second column formula is:

Informat( Substr( :Column 1, 12, 2 ) || ":0", "hr:m" )

The format required needs to have minutes along with the hour, so I just had to add it to the string returned from the Substr() function

I hope this helps you with your journey into using JMP
