JMP 18 Import Multiple File, imports duplicate columns appends with 1, 2, etc. with no defined order.
May 12, 2025 04:36 PM

Issue

Importing a file with multiple columns with the same name will have no clear defined order. In earlier JMP versions, the columns would import as Column 1, Column 2, Column 3, etc. Now, they import as column 3, column 2, and column 1 without any clear ordering. 

Workaround

Import the files using JSL or File > Open and concatenate the tables.
