I am reading Excel file with JSL, first 2000 rows of column are numeric, followed by rows with characters. How do I make sure the column is read as character?
Hi @gfirmstone , another option would be to directly specify character datatype for that column, see https://community.jmp.com/t5/Discussions/Force-Excel-Import-Wizard-to-Use-Character-for-All-Columns/m-p/460732.
One of the Excel input options that can be specified is
Scan Whole File
Specifies how long JMP scans the file to determine data types for the columns. This is a Boolean value. The default value is true; the entire file is scanned until the data type is determined. To import large files, consider setting the value to false, which scans the file for five seconds.
Scan Whole File is the default.
Thank you so much, that worked perfectly! Really appreciate it.
