Microsoft Excel files open in the Excel Import Wizard by default. This option is helpful when the structure of data in the worksheet is irregular. For example, you might want to exclude hidden columns or convert text in the third row to column headings.
Instead of opening spreadsheets in the Excel Import Wizard, you can select File > Open to open the file. By default, JMP detects whether the first row contains labels and converts them to column headings. You can change this setting in the General preferences. The Excel Open Method preferences are in File > Preferences > General (Windows) and JMP > Preferences > General (macOS). From the Use Excel Labels for Headings list, select Always or Never.
